OVERVIEW
For over 35 years, Statek has supported military programs with both standard products (normally purchased without a drawing and
without modifications or special testing) and specialized products (normally purchased to a drawing and requiring modifications or
special testing). For those desiring standard products (not governed by a source control document) but still desiring construction
and testing to military standards, Statek offers a portfolio of oscillators manufactured and tested to MIL-PRF-55310, Product
Level B. Because of our dedication to servicing specialized needs and continued support of the military market over the years,
Statek is a preferred supplier to a number of major defense contractors.
GUIDELINES FOR MILITARY PRODUCTS
Materials
Statek uses only the highest quality materials from carefully selected suppliers. Whenever possible, we use domestic suppliers
and try to cultivate a long-term relationship to provide stable sources of high-quality materials. Statek’s incoming inspection
assures compliance to our requirements. We manufacture our crystals with ultra-pure synthetically grown alpha-quartz bars.
(Swept quartz is also available, e.g., for applications requiring radiation hardness.) To simplify and minimize the device circuitry,
we use oscillator-dedicated integrated circuits. Lastly, we design our own ceramic packages, which are then manufactured for us
by our package supplier.
Assembly
Statek optimizes its manufacturing process to guarantee high quality. Our time-proven assembly process includes many
proprietary techniques to ensure robust parts suitable for the harshest environments. All military oscillators are inspected to
MIL-STD-883 prior to seal.
Testing
In order to meet COTS (commercial-off-the-shelf) requirements, Statek offers oscillators meeting the testing requirements of
MIL-PRF-55310 Product Level B. However, Statek gladly accepts fully customized testing to meet your needs; just contact us
with your requirements.
Continuity
Statek offers the continuity of support required for long-term military programs. We maintain records so that we can trace each
delivery back through its manufacturing history. Statek also has production redundancy and an established Business Continuity
Plan, which will allow us to recover in the event of an unforeseen occurrence.
Quality Assurance
Statek uses the ISO 9001:2000 process approach model and plans its continual improvements in order to achieve total customer
satisfaction.
