Abstract
A crystal-controlled oscillator exhibiting reduced levels of crystal-induced low frequency noise, vibration sensitivity and circuit temperature rise includes an amplifier or oscillator sustaining stage which is secured to a heat sink. A plurality of crystals connected with each other in a preselected electrical configuration are secured to a vibration dampening structure which extends from the heat sink, and the plurality of individual crystals are connected with the oscillator sustaining stage via a preselected wavelength section of coaxial cable. The coaxial cable wavelength may be varied to provide that the plurality of individual crystals operate at either series or parallel resonance.
