Analysis and Design of a Novel ×4 Subharmonically Pumped Resistive HEMT Mixer

摘要

In this paper, a novel topology of an HEMT-based subharmonically pumped resistive mixer (SHPRM) is presented, i.e., the $times$4SHPRM. The presented topology requires only a quarter of the local oscillator (LO) frequency compared to a fundamentally pumped mixer (e.g., 15 instead of 60 GHz in a 60-GHz system). This reduction in required LO frequency provides a significant reduction in complexity of the overall radio front-end and reduces the dc power consumption as well as the occupied chip area. Thus, the $times$ 4SHPRM provides a significant cost reduction for a millimeter-wave system. Furthermore, the $times$ 4SHPRM can be used for both up- and down-conversion and it can be implemented in any field-effect transistor technology.
