Abstract

A SMT (SurfaceMountTechnology) MMIC(Monolithic Microwave Integrated Circuit) frequency multiplier(x2) and power amplifier has been designed for DBS(Direct Broadcast Satellite)and other commercial applications. Using PHEMT technology this MMIC takes a 15GHz input signal and passes it through a harmonic frequency doubler and then through three stages of power amplification at 30GHz. This MMIC provides an out put power of 21dBm, fundamental suppression of45dBc and is stable across all voltages and temperatures. This single MMIC SMT solution frequency multiplier and power amplifier is unique compared to any known or published data.
