DOI: 10.1002/mop.31555
Abstract: In this paper, a miniaturized microstrip quadrature hybrid coupler (QHC) using U-shaped transmission lines (USTLs) is presented. The proposed approach replaces all arms of the conventional QHC with its equivalent USTL to achieve compactness. The… read more here.

DOI: 10.1109/jssc.2022.3171570
Abstract: The proliferation of millimeter-wave (mmWave) bands across 24–90 GHz and the strict spectral efficiency requirements demand future transmitter front ends to operate across multiple bands with simultaneously back-off efficiency and high linearity—characteristics that typically trade… read more here.
