As RF Communications have expanded, channel spacing’s have been narrowed, operating frequencies are higher, and flters are the solution ECS has a wide offering of flters utilizing the following technologies: Ceramic Filters are traditionally used in FM radios and offer wider bandwidths than MCFs providing a low-cost flter solution.
Monolithic Crystal Filters (MCF) have very high Qs and excellent temperature stability, offer narrow bandwidths and are highly selective Surface Acoustic Wave (SAW) Filters are available at higher frequencies than MCFs and offer narrow or wide band passband with very good selectivity.
