A Temperature-compensated Closed Loop Overdrive Level Controller for Microwave Solid-state Power Amplifiers

The reliability of GaAs power FETs used in solid-state power amplifiers (SSPA) is adversely affected when operated in an overdrive (excess input power) condition for a long time due to excess gate current. Manufacturers of SSPAs use different schemes to protect the FET power devices from overdrive conditions. One...
