High Efficiency L-Band GaN Power Amplifier

This article illustrates the design and development of a 60 W pulsed Class F power amplifier over the frequency range of 1.25 GHz ┬▒ 50 MHz. The power amplifier has been designed and fabricated using a GaN HEMT transistor. This amplifier shows a competi...
The rapid growth of wireless communications, as well as space-borne systems, leads to the increasing demand of low power, high efficiency systems. High efficiency is the prime requirement for any space-qualified transmitter or wireless communication systems. Higher efficiency means greater output power with reduced power dissipation. Achieving higher efficiency...
