Abstract :
The authors present a fundamental YIG tuned oscillator which covers the frequency range of 2 to 22 GHz, using a high-frequency silicon bipolar transistor and a single YIG sphere. A unique composite feedback approach has been utilized to demonstrate a minimum of 10-dBm power output and phase noise of -95 dBc/Hz at 10 kHz across most of the band. The design approach and performance results of this widest-band and low-noise oscillator are described.<>
