Abstract
In an amplifier apparatus of the type including an RF power transistor output stage, the control circuitry of the invention provides an automatic gain control mode of operation for its power transistor of a first response time and a power limiting mode of operation for its transistor of a second, faster response time, and with the power limiting mode of operation being switched into effect in response to the sensing of the collector current flow of the power transistor beyond a prescribed value.
