概要

論文の詳細を見る
A 20GHz-band GaAs MMIC receiver module has been developed using 0.15μm HEMT technology process. It incorporates two front end low noise amplifiers, a double balanced diode mixer, and filters. The RF input frequency ranges 20.1 to 21GHz and the IF output 1.1 to 2GHz. Test results show an overall conversion gain of more than 27dB, and less than a 2.2dB noise figure. The image-rejection ratio greater than 21dB has been obtained. The isolation between RF and IF ports is better than 27dB, and between LO and IF is more than 50dB.
