Q-Tech claims QT625S/QT725S are industry’s best rad-tolerant SAW oscillators
Optimised for geosynchronous orbit (GEO) and other deeper space applications which require tolerance to radiation, the QT625S/QT725S series of space-qualified hybrid SAW oscillators have been introduced by Q-Tech. They offer 300kRad(Si) radiation tolerance, a wide operating temperature, phase noise floor and low vibration sensitivity, to meet the demands of satellite and space projects.
The 300kRad(Si) radiation-tolerant, sine-wave output QT625S SAW oscillators and, offering engineers expanded voltage control capability if desired, the QT725S voltage controlled SAW oscillators are available with user-specified frequencies from 400MHz to 1.3GHz. Frequency stability is over a wide operating temperature range (-40 to +85 degrees C). Low phase noise (-135 dBc/Hz at 10kHz offset and –168 dBc/Hz noise floor) and low vibration sensitivity (less than 2ppb/g) contribute to the stable and reliable operation, says Q-Tech.
The QT625S/QT725S devices are packaged in a hermetically sealed, 20-pin flat-pack 0.625 inch square (15.8mm square) package, available with straight or formed leads. The devices are screened to MIL-PRF-55310, Level S or Modified MIL-PRF-38534, Class K.
The QT625S/QT725S oscillators are available now with delivery of 20 to 24 weeks for engineering models without MIL-PRF screening and 42 to 48 weeks for flight models with standard MIL-PRF screening.
Q-Tech was founded in 1972, providing crystal clock oscillators and frequency control solutions for companies with demanding applications. The US manufacturer of qualified products to MIL-PRF-55310 also meets reliability standards such as Aerospace Corporation TOR (GPS III) and NASA GSFC specifications. Q-Tech services the military, aerospace, down-hole and deep space industries. It is certified to the AS9100 and ISO 9001 Quality Management Systems. The Company maintains a global presence with sales capabilities throughout North America, Europe, and Asia.
