Abstract
In this paper, the implementation of a 0.1 um GaAs pHEMT process MMIC LNA, a sub-harmonically pumped (SHP) mixer, and a single-chip receiver for 70/80 GHz point-to-point (PtP) communications are presented. In order to obtain high-gain performance and good flatness for a 15 GHz (71-86 GHz) wideband LNA, we use a 5-stage input/output ports transmission line matching method. In order to decrease package loss and cost, 2nd/4th SHP mixers were designed. From the measured results, the 5-stage LNA shows a gain of 23 dB and noise figure of 4.5 dB. The SHP mixer shows 2nd/4th conversion losses of 12/17 dB and an input P1dB of -1.5-+1.5 dBm. Finally, a single-chip receiver based on a 4th SHP mixer shows good gain results of 6 dB, a noise figure of 6 dB, and an Input P1dB of -21 dBm. © 2013 IEEE.
