Abstract:
A radio-frequency (RF) hybrid switch module comprising:a laminated body including a dielectric layer; a diplexer; a switching circuit; a low pass filter (LPF); a conductive pattern on said dielectric layer, for forming at least one of said diplexer, said switching circuit, and said LPF; a surface acoustic wave (SAW) filter mounted on said laminated body; a cover on said SAW filter, for forming a cavity which allows surface acoustic wave vibration and for hermetically sealing said cavity; a semiconductor switching device mounted on said laminated body, for forming a part of said switching circuit; a pad provided on said laminated body; a bonding wire connecting said SAW filter to said pad; and a potting resin covering said pad, said bonding wire, and said SAW filter.
