Abstract :
This paper describes a MMIC that has been designed using the GMMT Medium Power Foundry process which produces 5.4 Watts of power at 9.2 GHz with a PAE of 22%. Integral heatsink technology and power circuit design techniques have facilitated the design of a compact, densely packed circuit occupying 20 mm2 of GaAs. The small signal gain of the MMIC is 16 dB, with a 10 dB input match from 9 to 11 GHz. This MMIC is suitable for many X-band applications such as communications networks and safety radiolocation systems, but its high pulsed power output and low phase-gain distortion make it particularly ideal for use in phased array radar systems
