Q-Tech Corp. introduces the QT723 and QT735 Series of space qualified crystal oscillators, offering satellite and space craft designers exceptional performance in the industry’s smallest surface-mount packages. These New Space, Low-Earth Orbit (LEO) oscillators are 50 kRad (Si) total dose ionization radiation hardened, high shock (20,000 g) resistant and screened per MIL-PRF-55310, Level B with PIND.

The 2.5 mm x 3.2 mm QT723 Series offers models with user-prescribed 1.5 to 250 MHz, tri-state CMOS outputs powered by an input voltage of 1.8, 2.5 or 3.3 VDC. The QT735 Series, in a slightly larger (3.2 mm x 5 mm) package, is offered in CMOS, LVDS and LVPECL versions with input voltages up to 5 VDC and selectable frequencies from 1 to 250 MHz.  

“These two new series of New Space crystal oscillators are answering the need of aerospace system designers for footprint-saving devices, as they work to pack more functionality into their new LEO systems,” 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.”
