TDD Ka-band front-end with integrated switch on 22nm FDSOI CMOS technology is implemented for 5G NR at 24–28 GHz bands. Shunt switch technique reduces front-end performance only by 2 dB at 24 GHz compared to stand-alone reference amplifiers. Output power of TX with stacked PA is 13.6 dBm with 15 dB of peak gain, and RX front-end has 5dB noise figure at 24 GHz, both measured at the antenna port. Maximum average channel power at 28 GHz was 4.8 dBm with 100 MHz 64-QAM OFDM signal within 5G ACPR and EVM specifications. The PA and LNA amplifiers dissipate 183 mW and 4.6 mW from 2.8V and 0.8V supplies, respectively, occupying only 0.19mm2.
