Waveguide rotary joint or WRJ in electronic phraseology is a component used to pass on the microwave energy-frequency-from the stationary lines to rotating lines. They are also known as rotating couplers or RF rotary joints.

They are made of two waveguide-to-coaxial transitions which are connected by a coaxial line. As axial cables are circular, the WRJ can rotate about it without hindering its performance.

Waveguide rotary joint differs among itself in terms of physical dimensions, cross-sections and material used for its fabrication. It is noticed that most WRJ are rectangular, circular, or elliptic cross-sections. The most common materials used to fabricate a WRJ are aluminum, brass, bronze, copper, and silver.

However, WRJs are also made of stainless steel and specialty steels or caparisoned bi-metallic alloys. Dimensional details are the other parameters to consider for the said component.

Specifications of the waveguide rotary joint can vary depending upon the market being serviced by the manufacturers. However, WRJs are manufactured in accordance with the international electro-technical commission (IEC) standards. WRJs are also manufactured in accordance with the US military specifications.

It is important to take into account the general features before one narrows down the selection of WRJS. These features are single, double and quad-ridge has 1, 2 and 4 apertures respectively.

Some waveguide joints are flexible while others are twistable that interface with the circuitry through appropriate connectors.

The quartz crystal in an electronic oscillator needs to be maintained at a constant operating temperature to prevent changes in its frequency due to variations in the ambient temperature.

Therefore, in order to maintain the crystal oscillator at a required temperature, it is housed in an oven with the thermostat devise that indicates the existence of the calibrated oven temperature. Such an improvised devise is called OCXO-Oven controlled crystal oscillator.

Normal operating temperature of a standard commercial OCXO is 75 °C but would vary from 30 – 80 °C depending upon the set-up and that of its industrial version is specified to -40 – +85 °C

Thus, such a design of an OCXO prevents temperature drifts and provides the highest stability that a crystal oscillator can provide. Further, frequency stability is also fine-tuned by the types of cuts on the quartz crystal-AT Cut and SC Cut.

Therefore it is quite obvious that OCXO is predominantly used in applications where the frequency control is a crucial factor like radio transmitters, cellular base stations, defense communication devices, and precision frequency measurement equipment.

OCXO is bulkier in size, expensive and power-consuming. However, the frequency and temperature stability provided by OCXOs are much better than what the TXCOs provide.

Routine service checks are recommended to assess the health of performing elements.
