Abstract

This paper describes the design of a 30W GaAs pHEMT PA (power amplifier) for WiMAX applications. The PA is realized on a CuW carrier with various ceramic matching components. The PA attained 10dB small signal gain and 30W CW output power with a drain efficiency of around 60% at a supply voltage of 12V. Under WiMAX 802.16-2004 OFDM modulation (3.5MHz BW, 64QAM sub carrier modulation and peak to average ratio of 10dB) the PA achieves better than 2% EVM (error vector magnitude), -45dBc ACPR (adjacent channel power ratio) at 34dBm (2.5W) Pavg (average output power) with 16% average drain efficiency in a frequency band of 3.3-3.7GHz

用于3.5GHz WiMAX基站的30瓦功率放大器

本文介绍了一种用于WiMAX应用的30W GaAs pHEMT功率放大器的设计。PA是在带有各种陶瓷匹配元件的CuW载体上实现的。该放大器在12V电源电压下获得10dB小信号增益和30W连续输出功率，漏极效率约为60%。在WiMAX 802.16-2004 OFDM调制(3.5MHz BW, 64QAM子载波调制，峰均比为10dB)下，PA在34dBm (2.5W) Pavg(平均输出功率)下实现了优于2%的EVM(误差矢量幅度)，-45dBc的ACPR(相邻信道功率比)，在3.3-3.7GHz频段内平均漏极效率为16%
