摘要

The harmonic spur characteristics of a hybrid integrated S-band power amplifier (PA), consisting of both stages of LDMOSFET and AlGaN/GaN HEMT, are studied at different temperatures. The PA offers a peak output power of 50 dBm (100 W) with power added efficiency higher than 50%, and adjacent channel power ratio performance is less than −30 dBc. A temperature test chamber is employed for measuring the harmonic spur of PA from 233 to 393 K, and its linear response to temperature is captured at high output power level.
