digital radio receiver down converter modules for 21.2 to 23.6 ghz technical data description this digital radio receiver module provides the rf receive and down conversion function for 23 ghz digital radios. these modules offer excellent phase noise perfor- mance and can be easily phase locked to a frequency reference. the receiver module provides an output power of 3 dbm at the if frequency and is ideal for use in radios using 2 and 4 level fsk modulation. the excellent low noise figure is achieved by using the hewlett-packard phemt mmic technology coupled with an image reject mixer. the receiver module features an integrated ultra low noise silicon bipolar features low noise phemt mmic front end amplifier image reject mixer integrated silicon bipolar vco local oscillator low phase noise operated over -30 c to +70 c excellent tuning linearity sample output for phase locking DRR1-23XX vco operating in the s/c band as the local oscillator. a portion of the oscillator output is coupled off and is applied to a frequency divider network. the low fre- quency output from the frequency divider can then be easily used to phase lock the source. the local oscillator output is applied to a frequency multiplier network to produce the desired lo frequency to the mixer. applications this digital radio receiver module provides the total rf receive and down conversion function in radios operating in the 21.2 to 23.6 ghz band. block diagram mmic mmic msa-1100 mmic mixer mmic mmic bpf bpf rf input if output signal sample output tuning voltage receiver module 21.2 to 23.6 ghz lo x3 +4 amp amp lna amp x2a
