SAW oscillators feature rad-hardness for spacecraft use

May 5, 2020 By Aimee Kalnoskas

QT625S/QT725S Series SAW oscillatorsQ-Tech Corporation introduces the QT625S/QT725S Series of space-qualified hybrid surface acoustic wave (SAW) crystal oscillators, offering satellite and spacecraft designers exceptional performance for geosynchronous orbit (GEO) and other deeper space applications requiring the utmost in tolerance to radiation.

The 300kRad(Si) radiation-tolerant, sine-wave output QT625S (SAW) and QT725S (VCSO) oscillators are available with user-specified frequencies from 400MHz to 1.3GHz with exceptional frequency stability over a wide operating temperature range (-40°C to +85°C). Low phase noise (-135 dBc/Hz at 10kHz offset and –168 dBc/Hz noise floor) and low vibration sensitivity (less than 2ppb/g) combine to provide stable and reliable operation.

The QT625S/QT725S Series is packaged in a hermetically sealed, in a 20-pin flat-pack 0.625” square, available with straight or formed leads. The devices are screened to MIL-PRF-55310, Level S or Modified MIL-PRF-38534, Class K. The QT725S Series VCSO offers engineers the expanded voltage control capability if desired.

The oscillator series is available now with delivery in 20-24 weeks (Engineering models w/o MIL-PRF screening).
