Crystal oven temperature controller.

A crystal oven is a temperature controlled chamber used to maintain the quartz crystal in electronic crystal oscillators at a constant temperature in order to prevent changes in the frequency due to variations in ambient temperature. This oven temperature controller is suitable for such purpose. Crystals crystal oven red optronics supplies a special designed crystal oven and temperature controller for heating and stabilizing crystals at a predefined temperature.

Although this circuit is small and simple the design use a pwm output to preserve the efficiency. Here is the schematic diagram of the temperature control circuit. Miniature crystal oven temperature controller module for two way radio applications. The ch 25 is an affordable alternative to professional channel element temperature compensation.

The temperature of a quartz crystal for oscillator should to be kept constant to operate at very stable frequency. Such an elevated temperature is often required for noncritical phase matching ncpm or to avoid optical damage of crystals. Crystal oven controller microwave l o.
