Abstract
In this paper we report ultra-low-noise amplifier modules
and amplifier module chains for V-band (50-75 GHz). The
amplifier chips were fabricated in Northrop Grumman
Corporation's (NGC) 35-nm InP HEMT technology and
packaged in WR15 waveguide housings utilizing alumina
E-plane waveguide probes. The amplifier modules achieve
18 to 27 K noise temperatures from 50 to 75 GHz when
cryogenically cooled to 21 K. When measured through a
mylar vacuum window, a cascade of two amplifier modules
achieves a receiver noise temperature of 18.5 K at 58
GHz. A second chain has a measured receiver noise
temperature between 20 to 28 K for the whole V-band. To
the best of authors' knowledge, these are the lowest LNA
noise temperatures for V-Band reported to date.
