A fully matched Ka‐band wideband pseudomorphic high‐electron‐mobility transistor (PHEMT) 1‐W monolithic millimeter‐wave integrated circuit (MMIC) high‐power amplifier (HPA) without any external circuit is developed. The two‐stage HPAs are prepared on 2‐mil GaAs substrates with a small chip size of 3.46 × 2.9 mm. At least 10‐dB small‐signal gain, 29.5 dBm P −1dB , 31‐dBm P sat , and better than 12‐dB output return loss.
