Abstract Power Amplifier Design
The development of PHEMT, 24 to 31GHz 2W/4W The MMIC PA design started from extracting scalable FET
power amplifier MMICs are described. The amplifier was equivalent circuit model parameters. A 400m FET that
designed with highly integrated distributed line-based is consists of four fingers with two via-holes was used
low-loss power combining design techniques utilizing a for the device characterization. Load-pull measurement
0.15μm GaAs PHEMT production process. The designed and Small-signal S-parameter measurement were used
2W/4W power amplifiers exh
