A 15-43.5 GHz Switched-Bit Phase Shifter for 5G Mobile Handsets
In this work, a broadband 15-43.5 GHz phase-shifter (PS) for 5G mobile applications is presented. To achieve broadband operation, the PS construction is based on allpass networks (APNs). The proposed design was implemented in $0.25 \mu \ m$ . BiCMOS and achieved an insertion loss (IL) of 9.5 ± 0.3 dB at 27 GHz and 13.2 ± 0.4 dB at 40 GHz, allowing operation in both 24–30 GHz and 37-43.5 GHz 5G bands.
