Low Phase Noise YTO Synthesizer

We have developed the synthesizer, YIG Tuned Oscillator (YTO), capable of setting the frequency of the microwave bands from 100 KHz to 4.5 GHz accurately using 0.1 Hz resolution and having superior spectrum purity where the SSB phase noise in 4 GHz output frequency is -129 [dBc/Hz] (10 KHz from the carrier).
