A transformer-feedback low-noise amplifier (LNA) implemented in 22-nm SOI-CMOS with interstage noise matching is described. The LNA peak gain is 21.5dB at 22GHz, with a -3dB bandwidth (BW) of 19-36GHz. Minimum noise figure (NF) is 1.7dB centered at 28GHz, and remains below 2.2dB across 10GHz. Third-order input intercept (IIP 3 ) is -13.4dBm at peak gain when dissipating 17.3mW. Input and output return losses are >10dB across 22-32GHz (effective BW). Modulation of the FET backgate voltage increases NF by
