Patent ID: 6856213

Claim:
A radio frequency (RF) hybrid switch module for switching between signals of a plurality frequency bands, comprising: a dividing circuit; a switching circuit; a low pass filter (LPF); an electrode pattern forming at least a portion of said dividing circuit, said switching circuit, and said LPF; a laminated body including a plurality of dielectric layers, said electrode, pattern being formed on at least one of said dielectric layers; a surface acoustic wave (SAW) filter corresponding to the frequency bands, having a grounding port, being mounted on said laminated body; a diode mounted on said laminated body, for forming a portion of said switching circuit; a grounding electrode formed in said laminated body; and a via-conductor directly connecting said grounding port with said grounding electrode; wherein said grounding electrode is formed on a farthest dielectric layer of said dielectric layers from a dielectric layer having said SAW filter mounted on said laminated body, or on a dielectric layer near said farthest dielectric layer.
