ABSTRACT:
A balanced filter includes: a filter that has at least one unbalanced signal terminal; a balun that is a lumped parameter balun that inputs or outputs signals with different phases generated based on a signal input or output from the unbalanced signal terminal of the filter, the balun being formed with an integrated passive device; and a mounting unit in which the filter and the balun are flip-chip mounted.
