摘要：
We present a band-reconfigurable quadrature hybrid (QH) for in-phase (I) and quadrature (Q) signal generation in a broadband Doherty power amplifier (PA) for millimeter-wave (mm-Wave) 5G application in a 45-nm RFSOI CMOS device technology. The band-reconfigurable QH has been implemented using a single transistor-based switch (SW) and its simulation results show an I/Q signal magnitude imbalance of less than 0.7 dB, and an I/Q signal phase imbalance of 88.7 - 90.5 degrees in 5G NR bands (n258,11257). The core area of the band-reconfigurable QH is 230 mu m x 110 mu m excluding the probing pads and input/output baluns for probing test.
