LAMINATED HIGH-FREQUENCY SWITCH MODULE

摘要

A laminated high-frequency switch module for selecting either a 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.
