Electrical Features
Stop band attenuation is specified to
within 455 add.gif (63 bytes)100KHz
Attenuation band width is specified by the width of:
CFT: 40dB and CF: 50dB


Note : For safety reasons, connect the output of filter to the IF amplifier through a DC blacking capacitor. Avoid applying a direct current to the output of ceramic filters.
