Supplier of crystal oscillators for space, military, avionics and high-temperature applications, Q-Tech Corporation, has introduced the QT780 Series of space qualified crystal oscillators, designed for use as primary clocks in low earth orbit, small communications and broadcasting satellites.

The QT780 series is offered with a broad range of operating frequencies (230kHz to 162.5MHz) to serve a variety of LEO programs and ECCN:EAR99 listing to facilitate procurement to qualified international customers.

Reliability is essential requirement for devices in this application, this series is supported by a combination of performance specifications, including: 50kRad(Si) total dose ionisation radiation hardening and 20,000g shock resistance. Optional screening per MIL-PRF-55310, Lvl B with PIND to meet DLA specs including particle impact noise detection is also available.

Q-Tech’s low profile, small footprint (five by seven millimetres), extreme high-shock hybrid oscillators consist of an IC operating at various supply voltages (1.8, 2.5, 3.3, 5.0V) and a miniature strip quartz crystal. The series is offered in selected ceramic package configurations from surface-mount (SMT) to straight leads and formed leads.

“The QT780 Series is designed to meet the new requirements of our customers in the fast-growing, large constellation satellite market,” said Scott Sentz, Q-Tech’s Director of Sales and Marketing. “We are applying our 35-plus years of knowledge, experience and space heritage to deliver this new generation of application-optimised devices.”
