Shanghai, China 4 Georgia Institute of Technology, Atlanta, GA 1 2 To support various emerging applications, such as 5G millimeter-wave (mm-wave) communications, low-earth-orbit (LEO) satellite communication (SATCOM), and jointed sensing and communication (JSAC), wideband mm-wave transceiver (TRX) front-ends are needed. However, three challenges exist, including wideband-low-noise receiving (RX), wideband high-efficiency transmitting (TX), and excellent isolation between TX and RX. Unfortunately, these three problems often intertwine with each other. Conventional TRXs employ switches in the signal path to isolate the RX and TX, which induces losses and linearity degradation. Moreover, the large parasitic capacitance of the power amplifier (PA) imposes significant equivalent capacitance at the input of the lownoise amplifie
