CERAMIC FILTERS

Overview

ECHO Microwave provides ceramic filters, duplexers and multiplexers from 100MHz to 12GHz.
These are suitable for both commercial (e.g. TETRA, LTE, GSM, DCS,UMTS,GPS, set top box at 75 ohm) and military applications (e.g. S-band, C-band systems).

Our ceramic filter products provide a compromise between cavity and lumped element designs, by offering high performance in a small size and at low cost. The high quality factor, "Q", of our devices ensures low insertion loss and high temperature stability.

All ceramic devices can be customized for specialized mounting configurations and input/output connector types and we offer both leaded and surface-mount manufacture. High power products are specified to 20W.Performance and reliability are our top priorities.

ECHO Microwave's design and manufacturing processes are subject to rigorous quality assurance procedures,which differentiate our products from those of our competitors. All of our ceramic devices come with a 2-year guarantee and are RoHS compliant.
