Abstract

A monolithic P-HEMT Ka-band low noise amplifier is reported. This circuit was developed for being used in the Back End module of the differential radiometers in the European Scientific mission Planck. An average noise figure of 2.3 dB from 28 to 36 GHz with an associated gain greater than 20 dB was measured, and it achieved a minimum noise figure of 1.8 dB at 29.5 GHz. The amplifier provided 28 dB of gain from 29.5 GHz to 32 GHz.
