ABSTRACT:
A switch block1includes: N inputs; M outputs; N amplification sections each of which amplifies one of each pair of 2N input signals which are generated by dividing N input signals supplied to the N inputs in two; N bandwidth conversion sections each of which subjects, to frequency conversion, the other one of each pair of 2N input signals; and a 2N×M switch section which outputs the 2N output signals, which are supplied from the N amplification sections and the N bandwidth conversion sections, to either: one of the M outputs; or none of the M outputs. With this arrangement, it is possible to provide a signal recombination circuit which can reduce the leakage of the input signals.
