ECHO Microwave's cavity band stop filters provide deep, precise rejection of targeted frequency bands while maintaining low loss across all other frequencies. The high unloaded Q of cavity resonators enables exceptionally narrow notch bandwidths with rejection depths that lumped element and ceramic designs cannot achieve at equivalent frequencies. These filters are critical for suppressing strong interfering signals from co-located transmitters, eliminating known spurious emissions, and protecting receivers in congested spectral environments such as multi-carrier base station sites. Our cavity band stop filters cover 100 MHz to 40 GHz, handle power levels up to 1KW, and are available in low-PIM configurations for WiMAX, LTE, and CDMA deployments. Each design can be customized for specific rejection frequency, bandwidth, depth, and mechanical interface.
