Q-Tech's B+ space qualified oscillators

Q-Tech's B+ space qualified oscillators

Available from APC Hi-Rel, Q-Tech’s B+ product line is a series of affordable, high performance space oscillators in a small form factor.

With an impressive space heritage, Q-Tech’s B+ high reliability hybrid crystal clock oscillators are renowned for high performance in a wide range of space projects, including the Mars Rover and the International Space Station.

Conforming to ultra-high reliability standards such as Aerospace Corporation TOR (GPS III) and NASA GSFC specifications, Q-Techs oscillators are used across a variety of package configurations ranging from flat-pack and DIP to miniature SMD. The B+ range includes a ruggedised crystal mount in a miniature package capable of handling tough shock and vibration conditions and 5x7mm SMD oscillators with 4-point mount crystal designs.

A pathway to space qualified oscillators

The B+ family offers project engineers many choices and options for space-qualified parts. Alternatively, to take advantage of shorter lead times and more competitively priced parts, customers can order class B versions, confident that a path to full space qualified parts exists.

Offering a wide range of frequencies

Q-Tech employs an active die such as FACT 54ACT3301NSC and a proprietary 0.8µm BiCMOS technology die for LVCMOS and LVDS logics. In addition, they offer a wide range of frequencies from 450kHz to 250MHz, of supply voltages and logics from 1.8Vdc to 5.0Vdc HCMOS, 5.0Vdc TTL, 2.5Vdc and 3.3Vdc LVDS and LVPECL.

Customised parts to meet specific requirements

Whilst Q-Tech’s standard parts range offers a wide choice of optimisable configurations, customers can also request optimised products to specific project needs and requirements. Q-Tech’s custom MCM part numbers give engineers the freedom to work with Q-Tech’s specialist design and manufacture team. Equally, Q-Tech fully supports legacy programs – with none of their oscillators ever being made obsolete. Drop-in replacement products, suitable substitutes or the ability to recreate the product you need ensures your space project has longevity throughout its lifecycle.
