Description

The Luff SLSM models are advanced technology single phase-locked loop frequency synthesizer designs. These are self contained system level components. These units offer excellent performance for many applications.

In this basic architecture, a tradeoff between frequency resolution and phase noise performance needs to be made. These units are packaged in a miniature connectorized housing. The designs offer flexibility and easy customization for your specific requirement.
