Through the use of noise-optimised, TO-packaged 3rd and 5th overtone SC-cut crystals and low-noise electronic circuits, KVG has designed new RF OCXOs that provide very low phase noise (LPN) and low G-sensitivity (LGS) and extend the range of applications for these kinds of small packaged OCXOs.
Hermetically sealed package.
For a 100 MHz output signal the phase noise at 100 Hz from the carrier is better than 135 dBc/Hz (optional –138 dBc/Hz); at 1 kHz offset it is already better than 157 dBc/Hz (optional 162 dBc/Hz) and at 10 kHz offset they provide 170 dBc/Hz (optional 175 dBc/Hz); the so-called ‘noise floor’ at 100 kHz from the carrier and higher is better than 175 dBc/Hz (optional -180 dBc/Hz).
In addition to their excellent phase noise performance, the new OCXOs provide low dynamic G sensitivity of better than 1 ppb/G (optional 0,5 ppb/G) for all three axes. The frequency stability vs. temperature is in the range of ±20 ppb in the temperature range of -20°C to +70°C. Extended temperature range versions are available on request.
SMD package.
Long-term stability (ageing) is better than ±3 ppm within 15 years. The parts are either housed in an hermetically sealed European standard package size of 36 x 24 x 20 mm for the through-hole part or in a smaller non-hermetic 25 x 22 x 15 mm SMD package assembled on tape and reel.
The devices are dedicated to many communication technology applications that require enhanced short-term stability and phase noise performance, such as reference clocks for microwave signal sources, professional satellite receivers, radar applications and many measurement and medical applications (magnetic resonance imaging).
Due to its low G sensitivity, the hermetically sealed package option is suitable for applications with demanding environmental requirements (shock, vibration, humidity, dust) such as military or avionic applications.
