Function Description   Technical Characteristics

Traditional ovenized crystal oscillators typically require long warm-up times to stabilize before a usesable frequency output is obtained. Frequency Electronics experience in hybrid technology has led to the development of a stable oven controlled oscillator without the normally long waiting time.

Technical Characteristics

The FE-2260A uses a thick film hybrid substrate for the oscillator electronic components. An SC cut crystal is mounted external to the hybrid but is physically attached to the same assembly. A heater element, which is part of the hybrid substrate, heats the crystal to maintain a constant temperature. Since there is little mass to heat and the heating element is directly beneath the crystal base, a very short warm-up time constant is obtained.

By seperately mounting the crystal in its own case, a more stable design is acheived and there is greater latitude in optimizing the crystal design for the intended application. This approach also increases reliability and immunity to vibration and radiation effects.

The use of hybrid technology also allows substantial size and weight reduction as compared to conventional designs.
