Abstract: A millimeter-wave power amplifier based on a coaxial-waveguide power-combining circuit is presented in this paper. A coaxial stepped impedance transformer is used to provide an impedance ...

Post-layout simulations of the proposed buffer amplifier are performed using 0.35 μm AMS CMOS process parameters and 3.3 V power supply. The circuit is tested under a 600 pF capacitive load. An ...
