Small and Effective Crystal Filters for High-Performance RF Design Applications

ECS Inc. offers a wide selection of monolithic crystal filters (MCFs) in both through hole and surface mount design (SMD) packages. These packages feature a broad range of center frequencies, including 10.7 MHz, 21.4 MHz, 45.0 MHz, 70.0 MHz and 90.0 MHz.

Choosing an MCF for Your Application

The monolithic quartz crystal filter offers the stability of a quartz timing device ideal for intermediate frequency filtering. The monolithic crystal design is both cost-effective and space-saving, which is ideal for today’s wireless and telecommunications applications. Through hole filters come in a variety of sizes, which are application-dependent, and ECS Inc. surface mount filters come in industry-standard set sizes. Both have their benefits, and the type of circuit board you build will dictate the type you’ll need.
