Crystal oven temperature controller. Latching relay driver 12 to 28v relay sequencer high current dc switch l s band lna microwave l o. 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. Miniature crystal oven temperature controller module for two way radio applications.

Ordering instructions on bottom of page. Such an elevated temperature is often required for noncritical phase matching ncpm or to avoid optical damage of crystals. Crystals crystal oven red optronics supplies a special designed crystal oven and temperature controller for heating and stabilizing crystals at a predefined temperature. An oscillator of this type is known as an oven controlled crystal oscillator ocxo where xo is an old abbreviation for crystal oscillator.

Here is the schematic diagram of the temperature control circuit. Crystal oven controller this oven and precision temperature controller is used to hold a crystal and maintain it at an elevated temperature. Although this circuit is small and simple the design use a pwm output to preserve the efficiency. 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.
