Abstract
An optical controlled switch circuit for controlling a two-way voltage drn microwave switch. The optical controlled switch circuit includes, a light source, a control connected to the light source, an optic fiber having an end coupled to the light source, a field effect transistor coupled to a second end of the optic fiber, an inverting dc amplifier means coupled to the field effect transistor, a non-inverting dc amplifier means coupled to the field effect transistor, and a two-way voltage driven microwave switch having signal inputs respectively coupled to the inverting dc amplifier means and to the non-inverting dc amplifier means and having a microwave input and having first and second microwave outputs.
