Abstract :
A novel high gain, high power, high efficiency and high linearity MMIC power module is developed for a 20 GHz transmit phased array for future communication satellite application. This MMIC module has a maximum gain of 50 dB, a gain range more than 30 dB, an output power of 1.1 Watt, an efficiency of 18% and a third-order Intermodulation of 17 dBc at 19 GHz. It has a size of 4.5/spl times/1.75/spl times/0.5", a mass of 100 gm and a DC power consumption of 6.3 Watt.
