A laminated high-frequency switch module for selecting either transmission circuit or a reception circuit of each of transmission/reception systems by switching, comprising a demultiplexer for demultiplexing signals of the transmission/reception systems, high-frequency switch circuits for selecting either the signal path of a reception signal from the demultiplexer to the reception circuit or the signal path of a transmission signal from the transmission circuit to the demultiplexer, and means for measuring the power of the transmission signal from the transmission circuit, characterized in that the laminate is composed of dielectric layers having electrode patterns, and the demultiplexer, the high-frequency switch circuits, and the power measuring means are constituted of electrode patterns in the laminate.
A laminate-type, high-frequency switch module for switching a transmission circuit and a reception circuit in a plurality of different transmitting/receiving systems, comprising a branching circuit for branching signals of a plurality of transmitting/receiving systems;
A laminate-type, high-frequency switch module for switching a transmission circuit and a reception circuit in a plurality of different transmitting/receiving systems, comprising high-frequency switch circuits for switching signal lines of a plurality of transmitting/receiving systems, and, downstream of said high-frequency switch circuits, a branching circuit for branching signals of a plurality of transmitting/receiving systems, a branching circuit for synthesizing signals of a plurality of transmitting/receiving systems, and a means for detecting the electric power of a transmission signal sent from each transmission circuit, said laminate being constituted by a plurality of dielectric layers having electrode patterns, and said branching circuit, said high-frequency switch circuits and said electric power-detecting means being constituted by said electrode patterns in said laminate.
