Q-Tech’s latest space-qualified hybrid SAW oscillators offer 300kRad(Si) radiation tolerance, wide operating temperatures and excellent phase noise floor and low vibration sensitivity.
The QT625S/QT725S series of space-qualified hybrid surface acoustic wave (SAW) crystal oscillators offers satellite and spacecraft designers exceptional performance for geosynchronous orbit applications. The series also offers the utmost radiation tolerance for engineers working on deeper space applications.
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. Both exhibit exceptional frequency stability over a wide operating temperature range (-40°C to +85°C). In addition, they have low phase noise (-135 dBc/Hz at 10kHz offset and –168 dBc/Hz noise floor) and low vibration sensitivity (less than 2ppb/g), combining to provide stable and reliable operation.
QT625S and QT725S
The QT625S/QT725S series is packaged in a hermetically sealed, 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 gives engineers the expanded voltage control capability if desired.
The new hybrid SAW oscillators have been developed to meet the critical needs of satellite manufacturers for ultra-high-reliability components in arguably the most environmentally stressful environments. Q-Tech, the world’s leading supplier of crystal oscillators for space, military, avionics and high-temperature applications have applied over 35 years of knowledge, experience and space heritage to deliver this latest line of space-qualified devices.
