A fully differential 40 GHz amplifier in 90 nm CMOS technology thought to be used in a LO distribution network is presented and discussed in this paper. The amplifier, consisting in a 2-stages cascode amplifier, reaches 14.4 dB small signal gain and 7 dBm saturated output power consuming only 63 mW. The occupied area is 0,47 mm2 pad included. The detailed design procedure and the on-wafer measurement process are presented in this paper.
