Abstract :
A two-stage monolithic microwave integrated circuits (MMIC) broad-band power amplifier with AlGaAs/InGaAs/GaAs pseudomorphic high electron mobility transistor (PHEMT) has been developed for the up-link and down-link applications for local multipoint distribution systems (LMDS) in the frequency range of 24 ~28 GHz. The amplifier has a small signal gain of 18.6 dB at 24.5 GHz and 16.7 dB at 27.1 GHz. It achieved output powers of 19.8 dBm with PAE of 19.8% at 24.5 GHz and 18.8 dBm at 27.1 GHz
