24 GHz low-noise amplifier in 0.18 µm CMOS technology

A 24 GHz monolithic low-noise amplifier (LNA) is implemented in a standard 0.18 µm CMOS technology. Measurements show a gain of 12.86 dB and a noise figure of 5.6 dB at 23.5 GHz. The input and output return losses are better than 11 dB and 22 dB across the 22–29 GHz span, respectively. The operation frequency of 24 GHz is believed to be the highest reported for LNA in a standard CMOS technology.
