Abstract
A monolithically integrated low-noise amplifier (LNA) in 0.5 μm, 80 GHz Si/SiGe bipolar technology is presented. Measurement at 10.5 GHz gives a 50 n noise figure of 2.0 dB with a gain of 26 dB. This record noise performance for Si/SiGe LNAs is obtained by careful noise matching of the input stage optimised for the frequency band and technological parameters
