Abstract

Recent advances achieved in both the high frequency characteristics of microwave probes and the precision and stability of the hardware of the vector network analyzer have extended the present working domain to the millimeter wave length range. These performant measurements have been carried out. They have allowed the realization of a monolithic V-band low noise amplifier. It consists of two stages using 0.25 um HEMTs, and it exhibits more than 12 dB gain with 5 ± 0.5 dB noise over 10% frequency range at 57 GHz. The chip size (including matching and biasing circuits) is 1.0 x 1.5 mm2.
