This paper reports on experimental results of an optical gain control of a GaAs microwave monolithic integrated circuit (MMIC) distributed amplifier. The amplifier gain was varied by 15 dB and was controlled by a LED (250 μW) over the frequency range of 5‐8 GHz. The key to this investigation is the development of a simple inexpensive optical control mechanism that is compatible with MMIC fabrication methods.
