“…An optimum solution is to Apply MMIC technology to a front-end downconverter to determine the total receiver performance. We developed HEMT-based MMIC active mixers and downconverters with good performance, as a compact, high-performance frontend for a 60-GHz indoor communication systems [9]- [lo]. To keep costs low, a single chip configuration is the most suitable topology.…”

Using InGaPAnGaAslGaAs technology, we designed, fabricated, and evaluated a 60-GHz fully integrated HEMTbased MMIC receiver. The receiver consists of a four-stage lownoise amplifier (LNA) and a single-balanced active-gate mixer, a 60 GHz local oscillator (LO) , and a buffer amplifier for the LO. The HEMTs in the receiver have gates 0.1 pm long and 100 pm wide. The receiver had a conversion gain of greater than 17 dB from60.2 GHz to62.3 GHz,and the maximumconversion gain was 20 dB at 62.2 GHz. The noise figure of the receiver was less than 6 dB for IF frequencies between 100 MHz and 1 GHz for a 61.536 GHz LO, and the minimum noise figure was 4.9 dB at 1 GHz IF.
