Abstract

In this paper, a high linearity, high efficiency 1.9 GHz power amplifier sub-system using a 50 mm AlGaAs/InGaAs/GaAs PHEMT for PHS 500 mW base station is demonstrated. Under 10 V and 3.8 A bias condition, the output stage amplifier has achieved 12.5 dB small-signal gain, 43.7 dBm P1dB with 43% PAE and 44 dBm saturated output power with 41% PAE. For the amplifier sub-system, the ACPR at 600 KHz and 900 KHz offset from 1.906 GHz when operating at 38.5 dBm output power with π/4-DQPSK signal are better than 75 dBc and 79 dBc, respectively.
