The Golden Bootstrap oscillator from Quantic Wenzel provides ultra-low phase noise performance and low-g sensitivity of better than 5e-11/g below 300 Hz offsets, and 5e-12/g sensitivity above 300 Hz when vibration isolation is included.

This proprietary bootstrap oscillator technology is available from 80 MHz to 130 MHz and consists of two rugged oven-controlled crystal oscillators of the same frequency phase locked together. Special compensation techniques minimize vibration induced phase noise by mechanically aligning the two oscillators and summing a compensation voltage with the electrical tuning to the oscillators.
The Golden VHF bootstrap oscillator assembly is an ideal solution for the most demanding airborne, mobile and shipboard applications that require greatly improved dynamic phase noise under vibration. The oscillator with vibration isolation is housed in a 5.86 inch x 3.7 inch x 1.18 inch machined case. An internal voltage regulator provides excellent power supply line rejection. Device specifications can be modified to better suit user applications.
