FILTERS FOR FM APPLICATIONS–LOW LOSS, HIGHLY SELECTIVE, MINIATURE–SFE MA/MS/MJ/MH 10.7MHz
The standard SFE 10.7 line of ceramic filters are extremely reliable devices that exhibit excellent waveform symmetry. These filters have traditionally found wide application in FM receiver technology.
FEATURES
s These miniature filters have high mechanical strength.
s Low loss, favorable waveform symmetry, and high selectivity
s Various band widths are available for
applications in wide to narrow bands. s Small dispersion and stable
characteristics. s Change in center frequency is
typically within ±30ppm/°C at –20 ~ +80°C. s High reliability
