FOR FM APPLICATIONS–HIGHLY SELECTIVE G.D.T. FLAT TYPE
SFE MX/MA8/ML 10.7MHz
The SFE 10.7MX/MA8/ML lines of ceramic
filters were designed to minimize the
dispersion of amplitude and phase
characteristics within the pass band. Because
the excellent G.D.T. characteristics of these
filters insure signal integrity, they are
recommended for use in applications ranging
from high grade stereo receivers to digital
transmission systems.
low distortion. SFE 10.7 ML Series, in these
ceramic filters, being in harmony with
flatness of G.D.T., roundness of the
amplitude and selectivity characteristics,
therefore, these ceramic filters are suitable
to high-grade stereo tuners. Even if
mismatching condition, they can keep little
distortion because of low Qm of ceramic
material. The SFE 10.7 MA8 Series is
based on SFE 10.7 MA5/MS2/MS3, and
it obtains high selectivity with low loss.
There is little dispersion of amplitude and
G.D.T. characteristics, and low distortion
rate can be obtained.
