Abstract
This article presents a wideband millimeter-wave
(mmWave) receiver front-end that covers the frequency range
from 43 to 97 GHz, supporting the operation in the major parts
of the V-, E-, and W-bands. The front-end incorporates a passive
mixer-first topology to achieve high linearity and wideband
performance. The front-end adopts I/Q generation at the RF
port, using a coupled-line coupl er (CLC), rather than at the local
oscillator (LO) port to mitigate the crosstalk of the overlapping
I/Q LO sign
