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.
