The QT780 Series of space qualified crystal oscillators are 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 (230 kHz – 162.5 MHz) to serve a variety of LEO programs and ECCN:EAR99 listing to facilitate procurement to qualified international customers.
Exceptional reliability – an essential requirement for devices in this application – is 
supported by a combination of industry-leading performance specifications, including: 50 kRad(Si) total-dose ionization radiation hardening and 20,000 g 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 (5.0×7.0 mm), extreme high-shock hybrid oscillators consist of an IC operating at various supply voltages (1.8 V, 2.5 V, 3.3 V, 5.0 V) 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-optimized devices.”
