PIEZO FILTERS
MULTI-ELEMENT
HIGH PERFORMANCE CFM/CFJ/CFR/CFS/CFL 455kHz
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.
