| Popis: |
A 3.3-3.8GHz 2W MMIC power amplifier using AlGaAs/InGaAs/GaAs PHEMT for wireless local-area network and multi-channel multipoint distribution service applications is demonstrated. This two-stage amplifier is designed to match fully a 50/spl Omega/ input and output impedance. With dual-bias configuration, the amplifier possesses a 30.4dB small-signal gain, and a 34dBm 1-dB gain compression power with 37.1% power-added efficiency. Moreover, high linearity with a 41.5dBm third-order intercept point at a frequency of 3.5GHz is obtained. |
