MCF and SAW Devices

NKG offers a wide selection of Monolithic Crystal Filter (MCF) and SAW devices (SAW Resonators and Filters) in various thru hole and surface mount (SMD) packages. The monolithic crystal filter offers the stability of a quartz device ideal for IF filtering. The monolithic design is both cost-effective and space-saving; ideal for today’s wireless and telecommunications applications.
