Modeling of bonding wires array and its application in the design of a 120 W X-band internally matched AlGaN/GaN power amplifier

Abstract

This paper proposed a novel modeling method of bonding wires array for internally matched network for high power and high efficiency power amplifier design. Based on this modeling method, a 120 W X-band internally-matched AlGaN/GaN PA under continues wave (CW) condition is presented. The proposed power amplifier can provide a relatively stable output power above 50.6 dBm (115 W) and power added efficiency above 42% from 7.7 GHz to 8.7 GHz, while maintain a stable gain above 10.1 dB. This work is relatively competitive comparing with other state-of-the-art works.
