Abstract

A method for combining with a minimum isolation bandwidth includes: determining an insertion loss and an isolation between ports of a combiner; calculating a total isolation bandwidth of an isolation band in the combiner according to the insertion loss and the isolation between ports; determining guard bandwidths adjacent to the isolation band in combined systems, the combined systems being at least two communication systems combined by the combiner; and, calculating an actual isolation bandwidth of the combiner according to the guard bandwidths of the combined systems and the total isolation bandwidth.
