Abstract

In this paper, a high efficiency, low voltage, class-F power amplifier (PA) is described. The effect of different output harmonic terminations on the power-added efficiency (PAE) of the PA has also been analysed. A medium power PHEMT PA, operating at 900 MHz, is designed and measured. A peak PAE of 71.4% with 22 dBm output power (P/sub out/) and 14 dB power gain (G/sub p/) is achieved at a very low drain voltage (V/sub ds/) of 3 V. A PAE above 60% has been achieved over a bandwidth of 13%.

高效率的f类功率放大器设计

介绍了一种高效率、低电压的f类功率放大器。分析了不同输出谐波端对放大器功率附加效率的影响。设计并测量了工作频率为900 MHz的中功率PHEMT放大器。在极低的漏极电压(V/sub - ds/)为3 V的情况下，输出功率(P/sub - out/)为22 dBm，功率增益(G/sub - P/)为14 dB，峰值PAE为71.4%。在13%的带宽下，PAE达到了60%以上。
