Abstract :
Summary form only given, as follows. The ruggedness of HBT Class-C power amplifiers was improved by adding an anti-parallel diode to the amplifier input to limit the negative swing of the base-emitter voltage. The improved amplifier could withstand 3∶1 instead of 2∶1 mismatch in CW operation, and 2.5∶1 instead of 1.5:1 mismatch in pulse operation. The present approach is simple to implement and has negligible impact on overall amplifier output power, gain or efficiency.
