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. ■ All products are inspected for symmetry and roundness of amplitude FEATURES ■ Little dispersion of amplitude characteristics and phase characteristics (G.D.T. characteristics) ■ The SFE 10.7 MX Series has G.D.T. characteristics and is useful for obtaining DIMENSIONS MX SERIES MA8 SERIES ML SERIES Low Distortion High Selectivity, Low Loss Selectivity 7.0 ± 2 9.0 max.
