CAVITY FILTERS

Overview

ECHO Microwave's cavity filters, duplexers and multiplexers are available over the frequency range of 100MHz to 25GHz. These components provide low insertion loss, steep skirt selectivity and narrower bandwidths than ceramic filter solutions.

ECHO Microwave provides cavity devices manufactured to customer specifications including for low passive intermodulation, which is important for WiMAX, LTE, CDMA and PCS systems. The high performance of our cavity filter products is driven by our careful selection of materials and specialized design topologies and sizing. High "Q" DR-Puck resonators can be implemented to achieve both low insertion loss and high band-edge rejection. Our products are suitable for fixed and mobile applications in the VHF, TETRA, LTE, GSM, DCS, UMTS and GPS bands and for both commercial and military satellite networks in the S,C,X and Ku bands. ECHO Microwave offers a custom design capability with up to 12 frequency bands being used for demanding customer requirements. Quality is our top priority and our design and manufacture is subject to rigorous internal auditing and testing. All of our cavity filter products are guaranteed for 2 years and are RoHS compliant.
