Overview
FILTERS FOR COMMUNICATIONS EQUIPMENT RESIN MOLDED, MULTI-ELEMENT CFM/CFR455 SERIES The following lines of filters are high performance devices that achieve ultimate stopband attenuation through the use of multiple piezoelectric elements connected in ladder form.
A few of the recommended applications for these filters include high class receivers, SSB communications equipment, pocket pagers and mobile radios.
