| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MRFIC1807/D The MRFIC Line 1.8 GHz Power Amp/Switch Designed primarily for use in DECT, Japan Personal Handy System (PHS) and other wireless Personal Communication Systems (PCS) applications. The MRFIC1807 includes a single-stage power amplifier and transmit/receive switch in a low-cost SOIC-16 package. The amplifier portion employs a depletion mode power GaAs MESFET and produces up to +27 dBm output with +19 dBm input. On-chip power control circuitry allows bias adjustment for optimum performance. The T/R switch is capable of handling up to +28 dBm through the transmit path without significant increase in insertion loss. The switch is controlled by CMOS logic level signals -- no negative control voltage required. The MRFIC1807 is sized to be driven by the MRFIC1806 Driver/ Ramp IC. Together with the rest of the MRFIC1800 GaAs ICs, this family offers the complete transmit and receive functions, less LO and filters, needed for a typical 1.8 GHz cordless telephone. * Usable 1500 - 2200 MHz * 8.0 dB Gain Including Switch * +26 dBm Minimum Output Power at Antenna Port * 1.0 dB Typ RX Path Insertion Loss * Simple Off-Chip Matching for Maximum Flexibility * 3.0 to 5.0 V Supply * No Spurious Outputs for Load VSWR up to 8:1 * CMOS Level Switching Signal for T/R Switch * Order MRFIC1807R2 for Tape and Reel.

Output Power and Adjacent Channel Power Ratio versus Input Power MRFIC1807 6 MOTOROLA RF DEVICE DATA DESIGN AND APPLICATIONS INFORMATION DESIGN PHILOSOPHY The MRFIC1807 is designed to operate with the MRFIC1806 Driver/Ramp IC in 1.9 GHz Personal Communication System (PCS) applications such as Europe's DECT and Japan's PHS. The design incorporates a depletion mode GaAs power MESFET with a high-power transmit/receive switch and associated bias circuitry in one low-cost SOIC-16 package. The power MESFET is sized to produce at least 27 dBm saturated output power, including switch loss, from a 3.5 V supply, but the output power can be controlled using the PCNTRL input. This control voltage also allows setting of the quiescent current of the FET. PCNTRL can be set to give best efficiency or linearity for the particular system application. The TX/RX control pin allows fast switching of the T/R switch for TDMA applications. When switching from transmit to receive, the battery supply voltage should be removed from the PA (Pin 4), to avoid excessive current drain. This is usually accomplished using an external pass transistor controlled by the TX/RX signal. Alternatively, if PCNTRL is reduced to 0 V during RX mode, the bias current is reduced to nearly zero. The Transmit/Receive switch is a reflective MESFET design which is optimized for low loss and power handling in transmit mode. The design can handle 28 dBm of transmit power without significant increase in insertion loss. A regulated 3.0 Volt supply is required at pin 16 for the T/R switch and the bias and control circuitry. DECT APPLICATIONS Figure 2 shows the component values for a DECT implementation of the MRFIC1807. For use in equipment designed for DECT, the power amplifier is operated close to saturation to improve device efficiency. Maximum power output at the antenna connector is 24 dBm during a burst. The constant envelope characteristics of the GMSK modulation allow non-linear amplification without spectral regrowth. The transmit signal must be shaped or "ramped" to meet system transmit turn on time requirements of 10 msec minimum while not splattering into adjacent channels. A turn on time on greater than 2.0 msec has been shown to give adequate adjacent channel power performance. Most DECT realizations have the modulation applied to the transmit VCO so the most straight forward way of implementing this ramping function is at the power amplifier. The MRFIC1806 Driver/Ramp IC has an on-chip ramping circuit specifically designed for DECT. When ramped in this manner, the MRFIC1806 will supply the appropriately ramped RF signal to the MRFIC1807 which only has to be turned on and off with TX/RX. Alternate off- chip ramping can be implemented either with external components or at baseband. Consult the MRFIC1806 datasheet for more information. PHS APPLICATIONS For Japan's Personal Handy System applications, the modulation is p/4 DQPSK. When amplified with a non-linear amplifier, the signal will regrow the sidebands which have been carefully filtered at baseband, resulting in adjacent channel interference. To avoid this spectral regrowth, the amplifier must be operated "backed off" from saturation. The amount of backoff required has been shown to be a function of amplifier saturated output capability and may be as high as 5.0 dB. The PHS specification calls for a maximum average power during a burst to be 19 dBm. This is consistent with 5.0 dB backoff from the DECT operating point so the same DECT operating condition could be used. Alternatively, PCNTRL can be adjusted for a lower bias point to improve efficiency or higher bias for better linearity. With p/4 DQPSK modulation, ramping can be accomplished in the encoder so no external ramp circuit is needed. See the MRFIC1806 data sheet for further details.
