HIGH-FREQUENCY SWITCH MODULE

摘要

A high-frequency switch module which comprises a high-frequency switch circuit connected among an antenna, a transmission circuit, and a reception circuit and comprising switching elements and a surface acoustic wave filter connected between the high-frequency switch circuit and the reception circuit, uses a laminate constituted of dielectric layers having electrode patterns as the multilayered board, and has a phase correction circuit disposed between the switch circuit and the surface acoustic wave filter, wherein the high-frequency switch circuit comprises a switching element, a transmission line, and a capacitor as main elements, with at least a part of the transmission line and the capacitor constituted of an electrode pattern in the laminate, and with the surface acoustic wave filter mounted on the laminate.
