FILTERS FOR MUNICATIONS 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 remended applications for these filters include high class receivers, SSB munications equipment, pocket pagers and mobile radios.
