Abstract :
A very high efficient, low distortion C-band Hybrid-MMIC Amplifier using linear and non-linear models of the PHEMT devices has been developed. Double stage Hybrid-MMIC amplifier fabricated with 2×3.6mm gate width PHEMT and 2×12mm gate width PHEMT exhibits a power output of 40.2 dBm at 2dB of gain compression, a linear gain of 26dB and an associated PAE of greater than 46% in the frequency range of 3.8-4.2GHz.
