The phrase “crystal is the muscle, but rubidium is the mind” emphasizes how the hyperfine atomic resonance of rubidium physics circuitry in an OCXO disciplines the frequency pulse drift in rubidium oscillators.

Rubidium oscillator is basically an oven-controlled crystal oscillator (OCXO) with a built-in rubidium circuitry that further augments the timing accuracy, the amplitude, and the control of the OCXO frequency output.

Despite excellent accuracy, the OCXO periodicity of the frequency pulse tends to drift over time, causing the pulse to run faster or slower than it actually should.

The quartz oscillator’s rubidium physics circuitry engineered by Raditek into crystal oscillators detects and intercepts such shifts in timing or periodicity and instantaneously recalibrates it to the rubidium’s transition/cycle of 6 834 682 610.904 Hz, thus providing the right frequency oscillation periodicity.

Therefore, Raditek’s state-of-the-art Rubidium oscillators are considered to be the most reliable and accurate time standard and hence are used in telecommunications infrastructure, television broadcasts, GPS, aerospace, and defense-related systems because, besides precise timing, they are also designed to deliver low noise ratio, low G-force susceptibility, and stability over a wide thermal range of minus 30 to +60 degrees Celsius.

Aside from Raditek’s cutting-edge rigid standalone rubidium oscillators, they configure “20+ types” of formats/categories for tailored use in specific sectors and applications also at very compelling prices.

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.

Raditek’s state-of-the-art band pass filter is an authorization manager of the systems and applications it is used in. It is a firewall component that lets only a calibrated range of frequencies propagates into the system while blocking and attenuating the rest.

Radtek’s cutting-edge band pass filter is the most preferred component of radio receivers, transmitters, audio processing systems, and medical devices, as it has a shrewd screening ability.

It astutely isolates the desired signals, indemnifies them from Noise and allows only the clean, calibrated, and authentic frequencies to pass through it.
