摘要

本文介绍了一种工作频率为1.2GHz的DC-DC变换器的设计和特性，在输出功率为4.6W时，最大效率为75%，在效率为58%时，最大输出功率为13W。微波变换器由一个氮化镓e类功率放大器和一个氮化镓e类整流器组成。该电路是平面的，在75%效率点的功率密度约为0.65W/cm3。整流器可以与输入门驱动或与单个射频输入自同步操作。

A planar 75% efficient GaN 1.2-GHz DC-DC converter with self-synchronous rectifier

This paper presents the design and characterization of a DC-DC converter operating at 1.2GHz with a maximum efficiency of 75% at 4.6W output power, and with a maximum output power of 13W at 58% efficiency. The microwave converter consists of a GaN class-E power amplifier coupled to a GaN class-E rectifier. The circuit is planar and exhibits a power density of approximately 0.65W/cm3 at the 75% efficiency point. The rectifier can be operated with input gate drive or selfsynchronously with a single RF input.
