Crystal Oven Temperature Controller

The temperature of a quartz crystal for oscillator should to be kept constant to operate at very stable frequency.

Crystal oven temperature controller.

An oscillator of this type is known as an oven controlled crystal oscillator ocxo where xo is an old abbreviation for crystal oscillator. 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. Here is the schematic diagram of the temperature control circuit. Miniature crystal oven temperature controller module for two way radio applications.

Latching relay driver 12 to 28v relay sequencer high current dc switch l s band lna microwave l o. This oven temperature controller is suitable for such purpose. 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.

Although this circuit is small and simple the design use a pwm output to preserve the efficiency. Ordering instructions on bottom of page. Crystal oven controller this oven and precision temperature controller is used to hold a crystal and maintain it at an elevated temperature. The ch 25 is an affordable alternative to professional channel element temperature compensation.
