1. Field of Invention
The invention relates to a switch circuitry and a communication device and, in particular, to a switch circuitry and an access point.
2. Related Art
The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
FIG. 1 is a schematic view of a switch circuitry according to a preferred embodiment of the invention;
FIG. 2 is a schematic view showing the detailed structure of the switch circuitry shown in FIG. 1;
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
With reference to FIG. 1, a switch circuitry 10 according to a preferred embodiment of the invention, which corresponds with a plurality of antennae, includes a first switch module 11, a second switch module 12 and a third switch module 13.
As shown in FIG. 1, the first switch module 11 includes a first control lead C01, a second control lead C02, a third control lead C03, a fourth control lead C04, a first signal lead R01, a second signal lead R02, a first antenna lead A01, a second antenna lead A02, a third antenna lead A03, a fourth antenna lead A04, a first transmission lead T01, a second transmission lead T02, a third transmission lead T03 and a fourth transmission lead T04. The first switch module 11 couples the first signal lead R01 and the second signal lead R02 to two of the first antenna lead A01, the second antenna lead A02, the third antenna lead A03 and the fourth antenna lead A04 according to a plurality of control signals S01 to S04 inputted from the first control lead C01, the second control lead C02, the third control lead C03 and the fourth control lead C04.
