Ceramic (DCF) Filters

Surface Mount Ceramic Filters for RF Design Applications

ECS Inc. offers a wide selection of DCF ceramic filters. Radio-frequency (RF) filters are designed to isolate and allow only intended frequency bands to pass. The new monoblock bandpass filters have been engineered and optimized to offer high-performance adjacent channel and noise rejections.

When your design requires suppression or selection of signal content from a range of frequencies, your application needs a DCF filter from ECS Inc. These ceramic DCF filters offer an overall bandwidth range from 5,150 MHz to 7,125 MHz and a center frequency range of 5,235 MHz to 6,525 MHz and can operate in a variety of temperatures. Typically, applications require them in pairs; see pair notations in the product listings below for more details. DCF filters are ideal for Wi-Fi 6 and Wi-Fi 6E applications and much more. Review our technical guide on Wi-Fi 6E to learn more.
