CAVITY FILTERS - Overview

ECHO Microwave's cavity filters, duplexers and multiplexers are available over the frequency range of
100MHz to 40GHz. 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 13 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.
