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
