Abstract :
A record of wideband 5 to 27 GHz power amplifier is achieved with 20 dB gain and 21 dBm output power in two stage monolithic form based on LGCIT´s 0.25 /spl mu/m PHEMT process. In design, we use a lossy matching technique to obtain a flat gain characteristic and use Cripps´ matching technique to obtain a flat output power characteristic. The chip size is compact 3.1 mm/spl times/1.2 mm. We present how to realize the wideband output, input and interstage matching networks.
