DESCRIPTION
The transmitter module provides +20 dBm of output power, ideal for use in radios using 2 and 4 level FSK modulation. The module features an ultra low noise silicon bipolar VCO operating in the S/C band. A portion of the oscillator output is coupled off and is applied to a frequency divider network. The low frequency output (less than 1 GHz) from the frequency divider can be easily used to phase lock the source. The main oscillator output is applied to a frequency multiplier network to produce the desired output frequency in the 23 GHz range. The output of this network is filtered then amplified by a GaAs MMIC device to produce the required output power. A detected sample of the output signal is provided to facilitate built in test of key radio components.
