An improvement of IM and power of high power amplifiers using RC-paralleled circuits with frequency selectivity

摘要

This paper describes the design method to improve IM and power of high power amplifiers by employing a RC-paralleled circuit with frequency selectivity in the design of input matching circuits. The RC-paralleled circuit decreases gain at low frequencies where the power level of inter-modulated signals becomes high, leading to a significant improvement of IM and power.
