Abstract :
In this contribution the possible applications, technology, design and measurements of a W-Band high gain LNA are given. The main features of the four stage LNA can be summarised as following: a 25 dB average gain with plusmn2 dB ripple from 70 to 105 GHz, where gain is higher than 21 dB on the entire 70-110 GHz range. LNA predicted noise figure is 2.7 dB between 80 and 95GHz and less than 3.2 dB up to 108 GHz while the chip´s power consumption is 35 mW. The technology used is a 70 nm GaAs mHEMT process from OMMIC.
