摘要: A substrate on which cavities having floors and steps is provided. End faces of a light-emitting device, an optical component, and an optical transmission line are abutted on one of the cavity for positioning, and end faces of a light-receiving device, an optical component, and an optical transmission line are also abutted on the other cavity for positioning. Integrated alignment of optical axes facilitates alignment of optical axes, and thus eliminates the need of a CAN package. Accordingly, the size and height of an optical communications module can be reduced.

摘要: A radio frequency (RF) hybrid switch module includes an antenna duplexer integrated with a surface acoustic wave (SAW) filter used in a mobile communication device such as a cellular phone. The switch module handles a transmitted signal and received signal of different frequency bands. A parasitic inductance due to a mounting of the SAW filter is reduced, so that an attenuation characteristic at a low frequency of the SAW filter is improved. The RF hybrid switch module includes: a dividing circuit; a switching circuit; a low pass filter (LPF); an electrode for forming at least a portion of the dividing circuit, switching circuit, and the LPF; a laminated body including a dielectric layer having the electrode formed thereon; a SAW filter which is mounted on the laminated body, corresponds to plural frequency bands, and has a grounding port; a diode mounted on the laminated body for forming a portion the switching circuit, a grounding electrode formed in the laminated body, and a via-conductor directly connecting the grounding port of the SAW filter.
