Overview
FILTERS FOR COMMUNICATIONS EQUIPMENT–RESIN MOLDED, MULTI-ELEMENT – CFJ/CFS/CFL455kHz 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.
