Power Amplifier Tackles WiMAX

摘要

Digital modulation formats place great demands on a communications system's transmit power amplifier. Systems such as WiMAX and LTE employ signals with high peak-to-average (PAR) power ratios, requiring power amplifiers with low error-vector magnitude (EVM) and good linearity. Fortunately, Micro-Precision Technologies, Inc. has leveraged gallium nitride (GaN) device technology into a line of high-performance power amplifiers for such demanding applications. The first model in the firm's new line is the MPT2527PA30, with 30-W output power from 2500 to 2700 MHz.
