This brief introduces a D-band receiver (RX) RF front-end (RFE) integrating a low-noise amplifier (LNA), a mixer, a local oscillation (LO) doubler with pre- and post-buffering stages, and an ...
Abstract: This paper presents a 90-nm CMOS radio-frequency (RF) front-end using the proposed sandwich-type concentric vortical transformer (CVT) for transmit/receive (TX/RX) switching in time-division ...
