Wenzel Associates has released low jitter phase noise sources featuring Blue Tops technology for operating and testing new components and systems. Such applications include radar local oscillators, communications systems, phase noise measurement systems and low jitter clocks for testing data converters and other high performance semiconductors. These systems often require a source that provides several frequencies at a time with virtually no spurious content and high quality phase noise.

The Blue Tops product line includes dozens of modules including amplifiers, oscillators, multipliers, dividers, mixers, detectors, filters and other RF functions. The modules typically contain amplifiers, attenuators, filters, voltage regulators, level detectors, and other ancillary functions in addition to the primary function in order to achieve function density while preserving the flexibility of connectorised components.

A multi-chassis standardised multiple-frequency source provides up to 35 low noise frequencies from 10 MHz to over 1 GHz and a custom chassis built with RF modules can synthesise additional frequencies.
