Abstract
The front-end module is composed of a multilayer substrate and surface-mounted components. The front end module constitutes antenna switches, filters, and a high frequency circuit comprising a band splitter circuit as well as the front end of the transceiver circuit equipped with a plurality of transmission/reception features whose communications systems are different. The multilayer substrate arranges a band splitter circuit pattern at the center in the plane direction and symmetrically arranges a plurality of antenna switch conductor patterns whose communications systems are different, with respect to the pattern for the band splitter circuit.
