Abstract:
1. A distributing apparatus that distributes a high-frequency signal received from a transmitting-and-receiving module of a first wireless terminal to transmitting-and-receiving modules of other wireless terminals when the transmitting-and-receiving module of the first wireless terminal transmits an output signal to the transmitting-and-receiving modules of the other wireless terminals with a wiring scheme, said apparatus comprising: at least four signal transmission lines each transmitting the high-frequency signal, each signal transmission line including an input/output port to the apparatus; a connecting node to which one end of each of said signal transmission lines is coupled such that said connecting node defines a shared end for all of said signal transmission lines, said shared end being on an opposite end along the signal transmission lines to the input/output port of each of the signal transmission lines such that each of said signal transmission lines being connected to each other said signal transmission line only through said connecting node, said shared end for transmission of signals of each of said transmission lines; a switch connector for switching between connecting said connecting node to a port for connecting another distribution apparatus and connecting said connecting node to a grounded resistor; an impedance converter, one end of the impedance converter connecting said shared end, an opposite end of the impedance converter connecting to the switch connector; and an attenuator, in the form of one or more chip resistors with a form factor of an integrated circuit chip, on each of the signal transmission lines and positioned near the connecting node, the attenuator on each signal transmission line attenuating the high-frequency signal.
