Card Assemblies

Wenzel Associates’ offers card assemblies in several standard form factors (VME, VXI, etc.) as well as custom configurations to provide one or multiple low noise frequencies to 16 GHz. Each card assembly is comprised of one or more industry leading Ultra Low Noise Ovenized Crystal oscillators, Blue Tops RF Modules and other hardware mounted or integrated on a card assembly, to provide a high performance frequency source with unparalleled phase noise performance. These card assemblies can be plugged into the respective backplane platform and are suitable for use as a low noise frequency source or clocking signal as a key element in a system. Custom card assemblies are available with short development time and low cost.
