Abstract :
A C-band transmit/receive (T/R) module using gallium arsenide (GaAs) monolithic chips has been designed for an active aperture radar. Three C-band T/R modules were built and successfully tested. It is demonstrated that, with interior open-loop calibration and power conditioning, excellent phase and amplitude tracking can be obtained over frequency, temperature, and power supply variations. A peak module output power of 12 W was achieved at an overall module efficiency of 20%
