Abstract
We demonstrated a novel self-oscillating up-conversion mixer with double-conversion structure in order to overcome a high conversion loss of a self-oscillating sub-harmonic up-conversion mixer. The self-oscillating double-conversion mixer consists of a self-oscillating up-conversion mixer and an up-conversion gate mixer, based on two 100 nm pseudomorphic high electron mobility transistors (PHEMTs). The mixer has an operating frequency of 77 GHz due to the double-conversion of self-generated fundamental LO frequency of 38.5 GHz. The mixer exhibits a good conversion gain of 3.87 dB and a phase noise of -92.9 dBc/Hz at 10 MHz offset. (C) 2016 Wiley Periodicals, Inc. View this article online at wileyonlinelibrary.com.
