Abstract
A limiter for a solid state power amplifier (SSPA) protects the amplifier against large peak, short duration noise signals while controlling drive level related phase shifts. The limiter limits noise signals to a safe input level for the power output section of the SSPA. It also uses a pair of resistor networks at its input and output to dampen reflected energy and thus control drive level related phase shifts.
