Abstract

Simulation results of a LC-ladder and capacitive feedback low noise amplifier over the 60 GHz unlicensed band is presented. A gain of 14.8 dB was obtained with S11 less than -7.6 dB and a noise figure of 6 dB. These results deviate significantly from theory however and as such possible explanations for these deviations are presented. Other design trade-offs present in very wideband designs at lower frequencies are also quantified and equations for the maximum corner frequency and bandwidth as a function of noise figure are derived.
