Characteristics and applications of dual-gate FET

In this paper, the DC characteristics and working model of a dual-gate FET are explained. A microwave self-oscillating mixer with local frequencies stabilization by dielectric resonators is designed and developed using a dual-gate FET. A high performance device is obtained. The experimental results have shown that at S-band, a conversion gain of 5.0 dB and a noise figure of 9.2 dB are obtained.
