Abstract

A CMOS 0.18 μm subharmonic mixer is experimentally demonstrated that uses active baluns at the local oscillator (LO) and RF inputs, as well as at the output. With this subharmonic mixer, a 2.1 GHz RF input and a 1.0 GHz LO input produce a 100 MHz output signal. The conversion gain is 8 dB, the LO and RF input reflection coefficients are better than −10 dB, and IIP3 is −8.5 dBm. © 2006 Wiley Periodicals, Inc.

## Abstract A truly balanced operation of a 5.2‐GHz Gilbert micromixer with a single‐ended input and a single‐ended output is demonstrated using 2‐μm GaInP/GaAs HBT technology. Because the micromixer has a single‐ended input, a passive LC current combiner is used to convert the mixer‐differential o
