An mm-Wave CMOS I-Q Subharmonic Resistive Mixer for Wideband Zero-IF Receivers

In this letter, we propose a novel wideband subharmonically pumped fully differential I-Q resistive mixer architecture, which eliminates the necessity for on-chip dc-blocking capacitors to integrate IF amplifiers. The proposed differential subharmonic mixer topology is verified by presenting a CMOS millimeter-wave monolithic integrated circuit (MMIC), which includes the mixer and two on-chip diffe...
