Abstract
A compact V-band GaAs MMIC chip set consisting of 1) a single highly integrated receiver MMIC with 6.5 dB N.F. and 2 dB conversion gain using a subharmonically pumped mixer and 2) a transmitter MMIC having a state-of-the-art 30-60 GHz doubler with 14.3 dB maximum conversion gain, 17.7 dBm output power and broadband RF characteristics has been successfully implemented with a refractory WSi/Au gate for high reliability. The HJFETs of these MMICs exhibited an MTTF of 4E7 hours at a channel temperature (Tch) of 130/spl deg/C. This result demonstrates high potential of our MMIC technology and to enable highly reliable and highly integrated V- and W-band systems.Keywords
