Title :
X-band GaInP HBT 10 W high power amplifier including on-chip bias control circuit
Abstract :
A monolithic two stage high power amplifier (HPA) has been developed for X band applications. This amplifier is fabricated on UMS commercially available GaInP/GaAs HBT process. The MMIC HPA provides about 10 W output power from 8.4 to 10.4 GHz with a mean power added efficiency of about 35 % and a mean small signal gain of 16 dB. The HPA was also validated in a wide temperature range (-30 - +80/spl deg/C) from small to large input signal and for extensive frequencies. The most significant feature of the new HPA is the use of on-chip bias control circuit allowing a linear control of collector current independently of the temperature.
