Abstract :
The authors report on the optical phase and gain control of GaAs microwave monolithic integrated-circuit (MMIC) transmit-receive modules with applications for active phased-array antennas. Phase shifts of 45 degrees were obtained with 50 μW of optical power, and amplifier gain was controlled 15 dB with 250 μW of light intensity. It is concluded that this approach can be extended to the millimeter wave range, is compatible with GaAs MMICs, has potential for fast response, is cost effective, and is compatible with parallel optical processing
