  • Power division network device
    Patent number: 8570115
    Abstract: The embodiment of the present disclosure discloses a power division network device, which comprises a shielding house and a circuit board. Two opposite surface layers of the circuit board are respectively provided with a signal transmission line and a coupling line. The signal transmission line and the coupling line are suspended in the shielding house. The coupling line comprises a coupling area, and a load interface and an output signal interface connected at the two ends of the coupling area. The projection of the coupling area on the surface layer where the signal transmission line is located falls onto the signal transmission line and forms thereon a projection area. The length of the projection area in the longitudinal direction of the signal transmission line is one quarter wavelength. Broadside coupling by way of making the projection of the coupling line fall onto the signal transmission line can realize the allocation and sampling of the signals transmitted in the signal transmission line.
