25 Watt X-band GaN PA MMIC Design

This case study describes the design and performance of a 25W X-band GaN PA MMIC designed on WIN's 0.25μm GaN on SiC process. The design has a small signal gain of over 25dB from 10 to 12GHz with a gentle positive gain slope. The saturated output power is over 25 W from 10 to 11.5 GHz and PAE is over 33%.
