Abstract

A high power broadband switch-mode core MMIC has been developed for an application in digital switch-mode power amplifiers, e.g., class S, for mobile communications. The three-stage design can be flexibly used at any frequency operating in UHF band up to a maximum digital bit rate of 3 Gbps, equal to a square wave frequency of 1.5 GHz. At 0.9 Gbps a maximum broadband output power of 20.5 W was measured at a drain efficiency of 76% and a power added efficiency of 70%. Controlled by a digital signal with a peak-to-peak amplitude of 3.5 V, a large signal gain of 25.3 dB was achieved.

基于宽带gan的开关模式核心mmic，输出功率为20w，工作在UHF

已经开发了一种高功率宽带开关模式核心MMIC，用于用于移动通信的数字开关模式功率放大器，例如S类。三级设计可以灵活地用于UHF频段的任何频率，最高数字比特率为3gbps，相当于1.5 GHz的方波频率。在0.9 Gbps下，最大宽带输出功率为20.5 W，漏极效率为76%，附加功率效率为70%。由峰间幅值为3.5 V的数字信号控制，可获得25.3 dB的大信号增益。
