Vibration Isolated

Wenzel Associates designs and manufactures crystal oscillators, fixed frequency systems, integrated microwave assemblies and synthesizers to X-band. Many are custom designs for environments which require very low noise performance under vibration. Wenzel has many vibration isolated oscillator designs, and vibration isolation is standard in Wenzel’s HF and VHF Citrine Series oscillators. The Citrine can be provided with mounting holes for isolators or the oscillator with shock isolators can be mounted into a standard external Citrine housing. When isolated in the housing, vibration testing is provided at Wenzel for the system as a whole. In some cases, the Citrine’s internal housing has two cavities, one for a very low noise crystal oscillator and a second cavity that houses a PLL, x2 stage, odd order multiplier stage (x3, x5 or x7), a high output amplifier stage or dividers. The additional cavity adds mass, which can drive the resonant frequency of the isolators below 35 Hz. The typical resonant frequency for the Citrine products which includes just the low noise oscillator is ~50 Hz.
