When using ceramic filters, it is most important to match the input/output load to impedance 330 ohm (LT10.7MA19 is 470 ohm matching). Waveform symmetry is damaged when reactance is added to the input/output load. 2. 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. 3. The LT10.7M 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.
