30 GHz (Ka-band) VSAT DVB-RCS Mixer-Driver multifunction MMIC

This paper presents the design and performance of a Ka-band VSAT DVB-RCS (Digital Video Broadcast -Return Channel Satellite) Mixer Driver multifunction MMIC developed on a 0.25 mum GaAs pHEMT process. The MMIC up-converts an IF signal at 1-1.5 GHz to a +16 dBm RF output at 29.5 -30 GHz with an LO at 14.275 GHz. It is intended to be used in conjunction with an SSPA to deliver 2 Watts into the return channel VSAT antenna. A second output frequency band at 28.15 -28.65 GHz is accommodated in the MMIC.
