Abstract :
A surface transverse wave (STW) resonator based oscillator was developed in response to SONET OC-48 application. A high-Q STW resonator was designed and fabricated in the work. The oscillator´s white phase noise floor is -170 dBc/Hz for carrier-offset frequency greater than 1 MHz. The oscillator´s phase noise level of -67 dBc/Hz at 100 Hz carrier offset. The electronic frequency tuning range exceeds ±200 ppm.
