A Wideband Calibration-Free D-Band Passive Phase Shifter With Frequency-Invariant Codes Over 24% Fractional Bandwidth

A Wideband Calibration-Free D-Band Passive Phase Shifter With Frequency-Invariant Codes Over 24% Fractional Bandwidth 150 150
Author(s): Basem Abdelaziz Abdelmagid, Yuqi Liu, Hua Wang

Abstract:

This work presents a compact 110–140 GHz bidirectional D-band passive phase shifter based on combining a 5-stage capacitively-loaded reflective-type PS (RTPS) with a wideband 0°/180° stage. The design achieves a 360° phase range with a resolution of 11.25°. By applying: 1) a wideband RTPS design methodology on the stage level; 2) frequency/switching-staggering techniques among the …

Abstract:

This work presents a D-band bi-directional CMOS double-balanced mixer (DBM) supporting data rates over 160 Gb/s with a 58-GHz RF bandwidth (112–170 GHz). The mixer employs four identical NMOS passive switches ( $12~\mu $ m/60 nm) in a DBM topology, providing the isolation between RF, LO, and IF ports. Both IF and RF …
