A dual-band subharmonic drain mixer based on single local oscillator

Research output: Contribution to journalArticle

Abstract

A dual-band subharmonic mixer is demonstrated that is capable of down-converting RF signals in two different bands using second and third harmonic components of the local oscillator (LO) signal. As the mixer requires only one LO, a simple and cost-effective structure is achieved. The drain bias (VDS) is switched to maximize the gain in each RF band. For demonstration purposes, a dual-band mixer is designed for RF signals at 2.41 and 3.61 GHz with single LO frequency at 1.2 GHz. The measured results show maximum conversion gains of -6.4 and -7.1 dB at 2.41 and 3.61 GHz, respectively.
