Abstract
A push-pull monolithic active isloator having a pair of MESFETs in common-gate and common-drain (source follower), parallel configuration. These two FETs are the same size and a diode is inserted between the gate of the source follower and the source of the common-gate FET. A D.C. blocking capacitor is included at the output. Another FET is coupled between the input and ground and responsive to a control signal to vary the current in a biasing resistor between the drain and gate of the source follower.
