Raditek rubidium oscillators are a benchmark product used by the manufacturer of highly sensitive and critically important systems, applications, and equipment, such as telecommunication infrastructure, TV broadcasts, global navigation satellite systems, and aerospace and defense sector applications that require highly precise amplitude and frequency oscillation cycles.

Our rubidium oscillators are oven-controlled crystal oscillators (OCXOs) whose output is linked to the rubidium circuitry, which corrects the timing, accuracy (the periodicity of oscillation), and amplitude precision—if needed—of the pulse at its output level.

We manufacture rubidium oscillators using cutting-edge manufacturing technology and are therefore acknowledged to be one of the best in the industry.

Raditek rubidium oscillators are engineered to be most stable even in the temperature range of -30 to +60 degrees Fahrenheit and have a better holdover period; hence, they are a notch above not only the conventional oscillators but even the OCXOs and hence are used as dependable time stamps.

Raditek rubidium oscillators are preferred whenever a system or application demands ultra-precision in frequency oscillation.

As a result, Raditek’s rubidium oscillators are used in telecommunication infrastructure, broadcasting, global navigation satellite systems, aerospace and defense sector applications, and other topologically challenging systems such as CDMA, WiMAX, and LTE base stations that require highly precise amplitude and frequency oscillation cycles.

Raditek’s state-of-the-art rubidium oscillators are compellingly priced.

Waveguide rotary joint is used to connect the two different types of RF waveguides in a communication system. With the use of a waveguide rotary joint, a free rotational movement can be achieved without degrading the performance of microwave RF signals.

A waveguide rotary joint component is an electro-mechanical component used to transmit microwave signals-radio bands or a pulse from other spectrum-from a stationary line to a rotating line or vice versa.

The needed electrical continuity in a waveguide rotary joint is achieved by using λ/4-chokes which eliminates metal contacts that are susceptible to metal fatigue and wear and tear.

A waveguide rotary joint can have both the waveguide ports a right angle to the rotational axis, or have a “U-style”, “L-style” or an “I-style” configuration depending upon the modules which are available across the frequency bands.

Most waveguide rotary joint use rectangular, circular, or elliptical cross-section made of aluminum, brass, bronze, copper, silver, stainless steel and metallic alloys.

Waveguide rotary joint is extensively used in airport surveillance radars, guided missile technology, and other radar applications.

Its rugged make, minimum phase WOW, stable phase linearity make a waveguide rotary joint a perfect fit for high power applications. These can also be which can also be custom-made for a specific design/application.

The quartz crystal in an electronic oscillator, the OXCO, needs 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.

The essence of time devices is their precision, and their intrinsic qualities, such as stability, longevity, and flawless operation in any environmental condition, make them appropriate for precision-related systems, applications, and devices.

Raditek provides such cutting-edge rubidium oscillators designed to deliver highly precise frequency reference.

Raditek-made rubidium oscillators ​are deftly engineered units configured ​with precise OCXO output ​connected to the built-in rubidium physics circuitry, which ​helps augment the accuracy ​by recalibrating the output in case of any detected errors in the amplitude of the OCXO ​pulse output​.

In other words, a crystal oscillator’s output fr​equency is harnessed to the rubidium transition, which detects the errors in the OCXO frequency at the output stage and instantly recalibrates it to the correct frequency pulse delivered by the rubidium atomic clock.

Raditek engineers know that precision timing is the key for speed, reliability, and accurate outcomes, which is of critical importance for systems and applications that need nanosecond-level timing accuracy, such as telecom, GPS, and scientific research, where further actions depend on the data delivery by the system.
