Abstract :
Power MMICs at frequencies from DC to 12 GHz have been designed on GMMT´s GaAs/GaInP HBT process. Typical circuits include power Darlingtons for wideband microwave instrumentation, X-band amplifiers for phased array radar and L-band amplifiers for wireless communications. The key advantages of the GaAs HBT for these applications include high frequency performance (fmax>50 GHz), high efficiency, good linearity, high output power density, high gain per stage, no negative power supplies and good low frequency noise performance
