june 1995 digital radio transceiver (supersedes ds3506-6.3, september 1994) DE6003 the DE6003 is a high performance frequency hopping microwave radio, designed for spread spectrum operation. it oper- ates in the 24 to 25ghz band. portions of this band are available for data transmission on an unlicensed basis in most countries on a shared basis with existing users (that include microwave ovens, intruder alarms etc). the radio is highly resistant to interference and has many other design features that ensure the most reliable data transfer possible (when used in conjunction with an advanced protocol). co-location with other simultaneous users (as well as interfer- ers) is possible, giving an unsurpassed data density in a given area. the radio has been designed specifically for portable computer applications (including use on the move). it is also suit- able for a wide variety of other applications including inventory control, point of sale terminals (including handheld) and data logging. ds3506-7.3 features n rapid frequency hopping with 1mhz channels 24 to 25ghz n designed to meet world wide standards n 625 kb/s data rate n highly selective receiver, wide dynamic range n high simultaneous user density n diversity for mobile applications n fast switching for support of advanced, interference resistant protocols n miniature size with low power consumption for handheld use fig.1 DE6003 functional block diagram ordering information DE6003-001 max. transmit power: 1 20dbm DE6003-002 max. transmit power: 1 22dbm 4 5 4 2 4 40/41 140mhz 700mhz 312mhz rxd rssi 350mhz saw 1 38mhz saw 2 90 channel select loadb 7 txd lo2 pll hopping pll s1 s2a rx/tx antsel power control tx pll 205-215 ghz s2b s2c antennas 2 switching regulator v cc ( 1 5v) v cc 2 5 ( 1 3v to 1 6v) v ee ( 2 5v) gnd related documents gps outline drawing number: m50633-a2 fcc rule 15.247 etsi ets 300-328 japanese specification number rcr std-33 iso9000 quality manuals gps application notes an142,143,144,145, 154 and 203 for further design information DE6003 digital radio transceiver
DE6003 2 external interface the DE6003 transceiver has a simple external interface, with all but three interface connections having cmos compatible switching levels: some inputs have pull-down or pull-up resistors. the DE6003 connection list, table 2, is followed by a description of each of the external connections in pin number order. on power up, the DE6003 transceiver should have its control inputs set to receive with the power amplifier off. on power switch-on, a channel within the 101 channels is selected by the value that is on the select data inputs sd(6:0); the correct channel should be loaded by placing the channel number on the select data inputs and strobing the channel data in with loadb. the antenna select input (antsel) is used to switch between the two antenna ports; this input should be set to antenna 1 for transmit and only switched when the transceiver is in receive mode for antenna diversity selection. the data input (txd) has data applied in simple non-return to zero (nrz) format with the maximum consecutive 1s or 0s limited to 16. receive data (rxd) is demodulated and output in nrz format with no clock extracted. the rxd output is designed to drive a high impedance cmos input with a maximum load capacitance of 6pf. loads in excess of 6pf will extend the negative edge time of the output data resulting in pulse stretching. all inputs input voltage low input voltage high paoff, pwrlo, antsel input current low input current high rx/tx input current low input current high loadb input current low input current high stdby input current low input current high sd (6:0), txd input current low input current high synlok output voltage low output voltage high rxd output voltage low output voltage high rise/fall time clk output current low output current high rssi output voltage low output voltage high ant1, ant2 isolation between ports negative supply, v ee output current output voltage ripple and noise characteristic value min. conditions/comments symbol v il v ih i il i ih i il i ih i il i ih i il i ih i il i ih v ol v oh v ol v oh i ol i oh v ol v oh i ee v ee electrical characteristics the electrical characteristics are guaranteed over the following range of operating conditions, unless otherwise stated: t amb = 0c to 1 55c, v cc = 5v 5%, v cc 2 5 = 1 3v to 1 6v. max. units v v m a m a m a m a m a m a m a m a m a m a v v v v ns ma ma v v db ma v mvp-p 15 v cc 2 10 10 2 600 150 2 400 10 2 10 200 2 10 200 05 v cc 12 v cc 150 2 16 16 33 30 2 15 2 525 50 0 35 2 400 50 2 250 0 v cc 2 05 0 38 75 2 025 025 0 10 0 2 475 v in = 0v v in = v cc =525v v in = 0v v in = v cc =525v v in = 0v v in = v cc =525v v in = 0v v in = v cc =525v note: not cmos compatible switching levels. at 1ma sink at 1ma source v cc = 1 5v at 100 m a v cc = 1 5v at 100 m a load = 6pf note: not cmos compatible switching levels. for load impedance < 300 w see an142 for interface circuit note: analog output, source impedance 10k w C not cmos compatible. see fig 9. nominal 50 w load on each port test at v cc 2 5 = + 5v at 2 15ma table 1

DE6003 5 running at lower temperatures. the thermal time constant of the radio is 1 minute and this derating curve can only be applied to transmitter for continuous transmit times of less than 20 seconds; above this time the duty cycle should be considered 100%. for continuous operation the case temperature should not exceed 40c. environmental limiting conditions of use l operational temperature: 0c to 1 55c. l storage temperature 2 20c to 1 70c. l humidity: 95% non-condensing. l esd: human body model, 4000v. l vibration testing: 10 t0 2000hz, displacement 6 1mm, acceleration 2g. operating temperature when in operation the transmitter power amplifier (pa) dissipates the highest amount of power and creates the highest temperature. in order to keep the temperatures to a safe level the environment in which the radio is operated must be kept within the values specified in environmental limiting conditions of use, above. the radio dissipates this heat from the whole of its surface, in particular from the metallic screen; steps must be taken to prevent overheating as early failure of the radio may occur. depending on the air temperature surrounding the radio, the pa duty cycle must be set to keep the dissipation to a safe value. the transmitter power amplifier derating curve of fig.2 shows the derating factors that should be applied in order not to exceed the maximum working temperature. running at the maximum permitted temperature on the pa will (as with all semiconductor devices) result in shorter operational life than air temperature ( c) 60 55 50 40 30 20 10 0 safe working area 0 20 40 60 80 93 100 pa duty factor (%) fig. 2 pa duty cycle state standby receive, ant 1, low power, pa off, setting channel 0 receive, ant 2, low power, pa off, setting channel 8 receive, ant 1, high power, pa off, setting channel 16 receive, ant 2, high power, pa off tx ready, ant 1, low power, pa off transmit, ant 1, low power, pa on transmit, ant 1, high power, pa on sd (6:0) x 0000000 0001000 0010000 x x x x antsel x l h l h l l l pwrlo x l l h h l l h paoff x l l l l l h h rx/tx x h h h h l l l stdby l h h h h h h h loadb x h h h h table 6 control signals truth table timing specifications and conditions of use the timing diagrams, figs. 3 to 8, show some of the normal sequences used in the control of the DE6003 and are used to illustrate timing relationships. table 6 is the truth table for these signals values for which are given in table 7. each entry in table 7 is described on pages 9 and 10.

DE6003 9 dynamic characteristics C notes to table 7 1. transmitter power output selectable by control line, to high or low output power setting. power levels are for any channel into 50 w and measured at ant1. output ripple is measured over 5 channels. 2. transmitter power amplifier control, paoff (t 1 ,t 2 and t 6 C see fig. 3) this control is used in conjunction with the rx/tx. paoff is included to allow the power amplifier to be turned on after rx/tx has been set low to transmit ( t 6 , rising to 90% in t 1 ) and off before being set high to receive ( t 2 ). the power am- plifier has been designed to switch on and off in this control- led way to avoid generating unwanted emissions which would be caused by simply turning the transmit power on and off. 3. transmit times when in transmit mode, the transmit (700 mhz) pll is opened, preventing the pll tracking the low frequency components of the transmitted data. this puts a limit on the maximum length of the data block which can be transmitted and places a requirement of a delay between switching to receive mode and transmit mode, in order for the pll to gain lock. 4. transmit delay this is the time to convert the txd data to the specified frequency (fsk) for transmission. it is specified as the delay from the 50% point of txd to the output frequency reaching 50% of its deviation. 5. receive mode to valid transmit data (t 7 C see fig. 3) this is the cumulative minimum time taken to: a. switch from receive to transmit mode, b. transmit to pa on delay (rx/tx to pa switch-on delay that must be allowed between switching from receive to transmit and turning on the pa in order for sufficient energy to be built up in the transmit chain before the pa is switched on), c. switch on pa and d. transmit delay 6. transmitter modulation (data onto carrier) spectrally shaped continuous phase frequency shift keying, spectrum-compliant with fcc 15.247. the DE6003 uses spread spectrum communication employing frequency hopping with spectrally shaped cpfsk as the modulation format. spectral shaping is achieved with a gaussian approximation pre-modulation filter. 90% of the power is within 1mhz bandwidth. 7. power on to transmit time this is the time from v cc being applied to the start of transmission of valid data at the antenna port. this value is very dependent on the power supply used, as all the decoupling capacitors on the DE6003 have to be charged and this energy must be supplied by the power supply. 8. standby to transmit (t 9 ) this is the time from standby to the start of transmission of valid data at the antenna port. 9. transmitter/receiver frequency agility (t 10 C see figs. 4,5,6 and 7) the DE6003 is designed to be used in a frequency hopping spread spectrum radio system. this requires fast channel switching, which is defined as the time taken from the rising edge of loadb to the required channel being within 40khz of the frequency required.the operating channel should not be switched until the output power has fallen to less than 10% after the power amplifier has been switched off when in transmit mode. 10.transmit/receive frequency select (t 13 , t 14 and t 15 C see fig. 4) the DE6003 transceiver will operate over 101 channels spaced at 1mhz intervals within the frequency band 2400 to 2500ghz. this is selected by setting sd (6:0) to the desired channel number and strobing in the data by pulsing loadb low. when loadb is low data ripples through a transparent latch, and is loaded into synthesiser data hold register on the rising edge of loadb. 11.receiver sensitivity a modulated signal of amplitude greater than or equal to the value specified in table 7 injected at either antenna port will exhibit a bit error rate of no more than 10 - 5 at 625 kb/s. gps measure this by applying a signal modulated with a pseudo random data stream (2 15 - 1)and modulated with an anritsu md6420a transmission analyser , together with a marconi instruments 2031 signal source for txd and a signal shaping filter with the characteristics of the DE6003 transmitter filter. the receive data clock used is the transmit data clock delayed by 400ns to enable centre-bit sampling (optimum sampling). 12.receiver max. input signal this is defined for all channels as the maximum receiver input signal level for a 10 - 5 bit error rate. 13. receiver data bit period (t 16 C see fig. 8) data bit period ( t 16 ) is the nominal time between each successive data bit.this period is subject to jitter on receive and will be continually changing within the bit period specification. the DE6003 is configured for 625 kb/s and data run length of contiguous 0s or 1s limited to 16 or less; any deviation from this may result in a lowering of sensitivity. the received rxd data stream will meet the bit width restrictions for 1s and 0s as defined in table 7. this is referenced to the nominal centre of a bit period. two bit width measurements are used to determine the correct operation of the demodulation circuitry, the first for pseudo- random data and the second to measure the effects of continuous patterns of 16 1s followed by a single 0 and of 16 0s followed by a single 1. note: received data (rxd) is considered valid when these specifications have been met.
DE6003 10 14.receive delay (t 18 ) as measured for 50% of the change of input frequency de- viation at either antenna port to the output on the rxd pin (9) of the 40 way connector. 15.frequency hop time to valid received data (t 19 C see figs. 6 and 7) this is specified as the time from the rising edge of loadb to data being within the bit period specification. (see note 13). 16.transmit to valid received data (t 20 C see fig. 3) transmit to valid received data (t 20 ) is specified as the time from the rising edge of rx/tx (this assumes that the pa has been instructed to turn off (paoff low) and pa fall time allowed to elapse before the rising edge of rx/tx) to data being within the edge jitter requirements. 17.rf burst to valid data (t 21 ) rf burst to valid data (t 21 ) is specified as the time from the start of a valid rf burst of data to valid data at rxd being within the bit period specification. 18.time to valid data after antenna selection (t 22 ) time to valid data after antenna selection (t 22 ) is speci- fied as the time from the change of antsel line to data being within the bit period specification. 19.channel rejection (modulated) the receiver selectivity is the ratio of the interfering signal to wanted signal power levels at which the bit error rate on the wanted signal is degraded to 10 2 5 . the wanted signal is applied at 10db above the measured sensitivity level using a prbs data pattern. the interferer is modu- lated by a different prbs data pattern with the same de- viation as the wanted signal.the interferer is then in- creased in level until the ber as measured on the wanted channel degrades to 10 2 5 . this is the rejection to unwanted signals and is measured at 6 2, 6 3 and 6 10 mhz from the selected channel. 20.channel selectivity (unmodulated) minimum rejection of signals at a frequency offset of 6 15mhz from the wanted signal, as defined in table 7. 21.receiver spurious rejection minimum rejection of signals in the bands below 18ghz and above 33ghz. all spurious responses better than the value defined in table 7. 22. receive signal strength indicator (rssi) the rssi output should be used for relative measure- ment purposes only. the output, which is a measure of the second if energy level, is neither calibrated for a given input signal strength nor to take account of production tol- erance variation of the receivers gain and losses. typical rssi response is shown in fig. 9. 23.rssi delay this is measured for 50% changed input amplitude at either antenna port to the time at which the rssi output (pin 31 on the 40-way connector) is within 10% of its final value. 24.frequency hop time to valid rssi (t 23 C see fig. 6) this is specified as the delay from the rising edge of fig. 9 typical rssi response 30 25 20 15 10 05 0 input signal (dbm) rssi (v) 2 120 2 100 2 80 2 60 2 40 2 20 0 loadb to valid rssi, when the rssi output is within 10% of its final value. 25.transmit mode to receive valid rssi (t 24 C see fig. 3) this is specified as the delay from the rising edge of rx/tx to valid rssi, when the rssi output is within 10% of its final value. 26.time to valid rssi after antenna selection (t 26 ) time to valid rssi after antenna selection (t 26 ) is specified as the time from the change of antsel line to the time at which the rssi output is within 10% of its final value. 27.receiver conducted emissions these are specified as the emissions measured, at either antenna port (terminated with 50 w ), with the transceiver in receive mode. 28.power off to receive valid data/rssi (t 27 ) this is the time from v cc being applied to the reception of valid data being within the edge jitter requirements and when rssi output is within 10% of its final value. these timing values are very dependent on the power supply used, as all the decoupling capacitors on the DE6003 have to be charged and this energy must be supplied by the power supply. 29.standby to receive valid data/rssi (t 28 ) this is the time from standby going high to the reception of valid data being within the edge jitter require- ments to the time at which the rssi output is within 10% of its final value. 30.frequency stability in order to be able to demodulate data in all specified environmental conditions the 10mhz reference oscillator frequency stability is as specified in table 7. 31.transmitter in band spurious emissions these are emissions in the transmitter output which are in the frequency range of 24 to 25ghz.
