Abstract
In this work, the design and measurement of a new
4x subharmonic mixer circuit is presented using CMOS 0.18
m
technology. With an RF input signal at 12.1 GHz, and an LO signal
at 3.0 GHz, an intermediate frequency of 100 MHz is produced

/76/79/41. The mixer uses a modified Gilbert-cell
topology with octet-phase LO switching transistors to perform the
quadruple subharmonic mixing. Included in the design is an active
balun for the RF signal and a circuit that generates a
