K/Ka-Band Eight-Way Power-Combined Power Amplifier in 180 nm E-Mode GaAs

Paper i proceeding, 2025

In this work, the design of a broadband K/Ka-band Power Amplifier (PA) Monolithic Microwave Integrated Circuit (MMIC) in 180 nm E-mode GaAs pHEMT technology is discussed. In small-signal the design has a flat frequency response from 23.8 GHz - 28.7 GHz covering a fractional bandwidth of 19.2%, with a maximum gain of 34.9 dB at 25.5 GHz. On top of that, the PA has a maximum output power of 28.5 dBm and a maximum Power-Added Efficiency (PAE) of 20.6%.
