!MATCHING CONDITIONS \ When using ceramic filters, it is most important to match the input/output load to impedance 330Ω (pure resistance). Waveform symmetry is damaged when reactance is added to the input/output load. \ Two ceramic filters directly connected can be used for high selectivity. For reducing waveform variation, it is recommended to input a buffer AMP between ceramic filters. \` The SFE 10.7 and SFT 10.7 series are of input/output symmetric structure so that in theory there is no input/output directionality. Actual circuits may use different input/output loading conditions (for example, mismatched impedance) or capacitance load. In such cases, the waveform will be a little changed by the direction of the input/output of the ceramic filters. 0 1.2 1.0 0.8 0.6 0.4 0.2 0 1.2 1.0 0.8 0.6 0.4 0.2 0 1.2 1.0 0.8 0.6 0.4 0.2 0 1.2 1.0 0.8 0.6 0.4 0.2 Frequency (M H z) Attenuation (dB) G roup D elay Tim e (µsec.)
