A compact subharmonically pumped MMIC self oscillating mixer for 77 GHz applications

Self Oscillating Mixer with Dielectric Resonator for Low Noise Block Application

“…By using these items a self-contained receiver for satellite television purposes can be realized. Some investigation of SOM has been studied extensively, such as dielectric resonator stabilized self oscillating mixers for fundamental frequency [1], balanced quasioptical self oscillating mixers of fundamental frequency [5], and self oscillating single device mixer of second harmonic [6]. In contrast to other mixers, the SOM developed here is designed to oscillate at 3.62GHz driven from 50Ω signal generator and is comprised of an MMIC comprised of two bipolar transistors coupled as a Darlington pair and a dielectric resonator to establish a local oscillator signal.…”
