Abstract :
A novel technique for reducing oscillator phase noise has been demonstrated. The technique utilized a pair of limiting diodes to keep the metal-semiconductor field-effect transistor (MESFET) operating a linear region. An X-band monolithic microwave integrated circuit (MMIC) oscillator was designed, fabricated, and tested to demonstrate the concept. A reduction of 15 dB in phase noise at 5 kHz from the carrier was measured.<>
