Abstract

A 39 GHz 5-bit switch type phase shifter (STPS) using 65-nm CMOS technology is presented for 5G applications. Utilizing the bridged T-type topology for 11.25°, 22.5°, 45°, 90° and 180° 1-bit phase shifters, the 5-bit phase shifter achieves low root mean square (RMS) phase and amplitude error with digital phase-control mechanism. The experimental results show that the measured RMS phase error of the STPS is less than 2.8° and RMS amplitude error is less than 1.2 dB at 39 GHz. The measured insertion loss of all 32 states is 14.5 ± 2 dB at 39 GHz.
