HI-REL/MIL

For over 35 years, Wenzel Associates has provided world class design, test and manufacturing of high reliability frequency sources and systems, with a proven record for meeting or exceeding demanding requirements with superior product designs and while making the process a collaborative effort. Our COTS and HI-REL frequency sources, and synthesizers are found in fighter jets and UAVs, on ships and in ground-based radars and in satellite links. Wenzel has provided the master oscillator and synthesizers for surveillance and reconnaissance aircraft, for detection and jamming radars and for secure communication networks.   A leader in Low-G sensitivity, Wenzel provides uncompensated oscillators to <1e-10/g per axis. Isolation systems provide g-sensitivities to <8e-13/g per axis and are frequently used under high vibration requirements. Wenzel’s Bootstrap dual crystal technology compensates oscillators to unprecedented levels at low offset frequencies without isolation systems - critical in shipboard applications.

 Many of our Military and Aerospace customers require custom frequency sources or assemblies built to source control drawings (SCD). See our Build to SCD/SOW page to learn more about our custom design capabilities.
