This white paper reports the design and performance of state-of-the-art GaN MMICs and a fully packaged Ka-band SSPA. Incorporating harmonic tuning, the MMICs produce power levels up to 10 W CW with efficiencies in the high thirties (42% peak) at frequencies of 30 to 34 GHz. These results represent the highest combination of CW power and efficiency at these frequencies. Download the full paper for more information.
