This paper describes a microstrip optically controlled matching technique between microwave active devices with low impedance (less than 10 ohms) and a conventional 50 or 70 ohm communication system in the upper microwave and mm-wave frequencies. The bandwidth is 20 GHz. the maximum insertion loss is less than 1.5 dB and the reflection coefficient is less than-7 dB. The laser controlled terminal impedance's can be changed and adjusted by choosing the carriers lifetime of the semiconductor substrate and by changing the power and wavelength of the optical source.
