abstract = {Two Q-band monolithic low noise amplifiers have been designed
and characterized. A study about depletion and enhancement
mode HEMTs with the same technology has been performed in
order to apply these results to the design of the low noise
amplifiers. These circuits have been developed for being used in
the Back End module of the radiometers in the European
Scientific mission Planck, because there are not commercial
circuits in this frequency band. The main goals for these
amplifiers are low noise with a small DC consumption. A
minimum noise figure of 2.8 dB with an associated gain of 23.1
dB at 40.4 GHz has been measured for the E-HEMT MMIC LNA
and its DC current consumption was 15.45 mA. The D-HEMT
MMIC LNA has a minimum noise figure of 3 dB with an
associated gain of 23.2 dB at 42 GHz and 30 mA of DC current
consumption.},
