Abstract

In this paper, a new power amplifier is proposed for reduction of amplified RX band noise signals as well as TX band intermodulation distortion signals using feedforward technique. This proposed power amplifier, contains two loops-TX band intermodulation distortion signals cancellation loop and RX band noise signals cancellation loop, can provide duplexer with low TX path insertion loss for various wireless communication systems due to choice of loose RX attenuation characteristic. The proposed amplifier is implemented for IMT-2000 base station frequency band. Experimental results represent that the cancellation performance of intermodulation distortion signals and RX band noise signals are more than 31dB and 21dB, respectively.
