  1. The metrics refer to the matched filters. The reported IL represents the minimum in-band insertion loss. The OBR is computed by averaging the values of S12 measured 1 bandwidth away from the center frequency, and the reported matching impedance is calculated by averaging the impedances of the two ports. In the same table, the filters from43 are also reported.
