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.

Applications

This digital radio module supplies the transmitter function in radios operating in the 21.2 to 23.6␣ GHz band. The source provides close to 100 mW output power over the temperature range of -30°C to +70°C. Included within the transmitter module is a muting function to reduce output power by 50 dB for “hot standby” appli- cations. An internal voltage controlled attenuator function is optional allowing for 30 dB dynamic range adjustment. 5965-5090E

Operation in excess of any one of these parameters may result in permanent damage. 2. A thermal interface medium must be used between the bottom of the package and its mating surface to ensure optimum heat transfer.
