MCF and SAW Devices
NKG delivers an expansive array of Monolithic Crystal Filters (MCF) and SAW devices, including SAW Resonators and Filters, in a variety of thru-hole and surface mount (SMD) configurations. Our MCF, constructed from stable quartz, are perfectly suited for IF filtering, combining cost-efficiency with a compact design. These attributes make them exceptionally well-suited for the demanding requirements of current wireless and telecommunications applications.
