A High-Resolution LO Phase Shifter with RF Gain-Invariant Phase Tuning for 5G New Radio
◎Jian Pang・Hisashi Kato・Atsushi Shirane・Kenichi Okada(Tokyo Tech)
An LO phase shifter designed for the incoming 5G mobile network is presented in this work. The phase tuning is realized with a two-step phase shifting at the LO path. A continuous phase shifting is achieved with less than 0.2dB RF path gain variation.
