POWER AMPLIFIER FOR IMPROVING PASSIVE INTER-MODULATION DISTORTION

摘要

PURPOSE: A power amplifier for improving passive intermodulation distortion is provided to minimize the effect of adjacent channel by improving the nonlinear characteristic of a power amplifier by using a specific power amplifier structure. CONSTITUTION: A driver(202) receives input modulated or non-modulated signal input from an input port(201). The driver generates output power for driving main amplifiers(203,204). The driver distributes generated output power. The main amplifier amplifies the input modulated or non-modulated signal to predetermined amplification level by receiving distributed output power from the driver. Isolators(205,206) minimize passive intermodulation by defining directional isolation level.
