Abstract
A single-chip CMOS transceiver (TRX) capable of
wireless data rates up to 80 Gb/s using part of frequencies
(252–279 GHz) covered by IEEE Std 802.15.3d is presented. The
TRX chip operates in either transmitter (TX) or receiver (RX)
mode at frequencies comparable to f
max of the NMOSFET. The
TX part adopts mixer-last architecture with four-way power com-
bining using a ring circuit called a double-rat-race. The RX part
adopts fundamental-mixer-first direct-conversion architecture. In
the RX mode,
