SERVING SPACE AND OTHER HIGH RELIABILITY APPLICATIONS

  • Q-Tech was the first company to use radiation hardened high-speed CMOS microcircuits in our space qualified oscillators.
  • Q-Tech has produced oscillators that have successfully survived total dose radiation levels over 1MRad(Si).
  • Q-Tech is currently offering Space level oscillators in Flat Pack/Butterfly (FP), Dual-In-Line (DIP), and Transistor-Outline (TO) packages at 3.3V and 5.0V, up to 300 kRad TID.
  • Q-Tech has full Radiation programs and libraries on all add-on components and products.
  • Q-Tech's successful Space Program is a direct result of an early company commitment to create a Program Management Office to effectively manage and direct the design, development, manufacturing and testing of the high reliability hybrid crystal oscillators produced by Q-Tech.
  • Q-Tech is qualified to MIL-PRF-55310/16 level "S"
  • Q-Tech has developed robust specifications for oscillators including the 401-0298-001, General Specification for Hybrid Crystal Oscillators, Class S

Now after more than 30 successful years in the Space hybrid oscillator business our customer base has grown to include the entire international space community. We are proud to be recognized as the supplier of choice for past, present and future space programs and appreciate these opportunities to serve our customers.

Q-Tech’s B+ product line is a series of space clocks in a small form factor, as small as 7 x 9 mm.

The B+ family offers many choices and options. This allows you to either order a full space version of the product, or else to order a class B version for quicker delivery and lower cost, with full knowledge that a path to full space part exists.

We employ an active die such as FACT 54ACT3301NSC and a proprietary 0.8µm
BiCMOS technology die for LVCMOS and LVDS logics. We offer a wide range of frequencies from 450kHz to 350MHz, of supply voltages and logics from 2.5Vdc to 5.0Vdc HCMOS, 5.0Vdc TTL, 2.5Vdc and 3.3Vdc LVDS. While we offer a range of optimizable configurations, we can also optimize your specific needs and requirements even further with a custom Q-tech MCM part number.

​SPACE PROGRAMS THAT Q-TECH HAS AND CONTINUES TO PARTICIPATE IN: MILSTAR, Cassini, TDRSS, GRO, DSP, AXAF, NSCAT, MESUR, Seawinds, MISER, MARS Pathfinder & Rover, FLCS, ICO, Gamma Ray Observatory, NSTAR, INTELSAT VII, Space Station Freedom, Globalstar, Tempo, COSTAR, GFO, ASCM, GPS IIR, Iridium, A2 100 Series Satellite, Mars Observer, Aussat, Navy UHF, ACSS, MODIS-N, Mars Observer Camera, EOS, ACES, Topex, Poseidon, International Space Station (ISS), Hot Bird, Ariane V, SMEX, HST, Midex, Herschel/Planck, Selene, Landsat, GPS III, Galileo, P, Block-3, Spectrum, MUOS, AEHF, WGS, INMARSAT, INTELSAT, Sierra, TDRS, Spaceway, Sky Terra, UHF, Mexsat, "702 platform" and many, many others.

Q-Tech maintains a robust radiation program with libraries on all add-on components and products. Information on Q-Tech radiation data can be found in our Application Notes.

TIMELINE AND HISTORY OF Q-TECH INNOVATION IN SPACE

2015 Q-Tech adds LVPECL logic to B+ space product line.

2014 Q-Tech introduced the QT625S and QT725S space level SAW clocks and VCSOs
2014 Q-Tech introduced the QT4200 Ultra Space OCXO, the smallest full-performance Space OCXO on the market
2009 Q-Tech introduces the B+ line of affordable high-performance space oscillators
2008 Q-Tech introduced the QT4100 Space OCXO
2005 Q-Tech introduced the new QT800 Series Space level TCXO, the most stable and lowest phase noise space TCXO on the market.
1999 Q-Tech received JPL/NASA Award for its contribution to the Cassini program.
1997 Q-Tech produced its first Space level VXCO.
1994 Q-Tech became the major supplier of hybrid crystal oscillators to virtually every satellite manufacturer in the United States.
1985 Q-Tech entered the Space Applications Market and received its first order for the MILSTAR program. In fact Q-Tech went on to receive TRW "Supplier of the Year Award" for the next two years in a row.
​​1972 Q-Tech was the first company to commercially produce hybrid crystal oscillators and the first company to appear on the MIL-O-55310 Qualified Products List for hybrid crystal oscillators.
