Abstract

One of the most important parts of communication systems are matching networks. If the matching networks are not broadband, no matter how good the rest of the communication system is, the system’s bandwidth is bounded by matching network. In this project, we explain the real frequency technique and use it to design and simulate a broadband matching network for use in a broadband power amplifier. The designed prototype operates from 0.1 up to 4 GHz with around 12 dB power gain and delivers approximately 40 dBm or 10 Watts of power. The power added efficiency of the device more than 47% in the wide operation bandwidth. CGH40010F GaN HEMT device of Wolfspeed-Cree Company is used in the design.
