Abstract
We have fabricated low noise V-band 2-stage amplifiers using PM-MODFETs which have a performance of 10.5 dB gain and 5.2 dB noise figure at 58.5 GHz in very close agreement with results predicted in advance. The CAE models for the transistors and the passive CPW-components were extracted from on-wafer S-parameter measurements up to 60 GHz and noise parameter measurements up to 18 GHz. For noise modeling of the MODFETs up to millimeter wave frequencies, we have pursued a novel approach which is based on the temperature noise model reported by Pospiezalski (1). A very good agreement between simulated and measured MMIC gain and noise performance is achieved up to V-band using these models.
