Abstract :
A technology is described which allows the monolithic integration of millimeter-wave Schottky diodes and MESFETs on one chip. The Schottky diodes have a cutoff frequency fT of 2300 GHz. A monolithic 60-GHz mixer chip using these diodes shows a conversion loss of 6 dB and a noise figure (DSB) of 3.3 dB. The MESFETs have an f max up to 70 GHz. A two-stage IF amplifier realized with this technology shows a gain of 20.6 dB and a noise figure of 1.7 dB at 4 GHz
