Patent ID: 8251721

Claim:
An active connector applied as an output end or an input end of a device that sends or receives signals, the active connector comprising: a connector base that has a first connection terminal and a second connection terminal, the first connection terminal being an internal port electrically coupled to a circuit inside the device, and the second connection terminal being an external port electrically coupled to a transmission line; a first matching circuit that is supplied an input signal inputted to the first connection terminal; a second matching circuit that supplies an output signal to the second connection terminal; and a buffer circuit that inhibits mutual influences between the input signal and the output signal, and is provided between the first matching circuit and the second matching circuit; wherein the first matching circuit, the second matching circuit, and the buffer circuit are housed in the connector base; and wherein the buffer circuit outputs an output signal in which at least one of signal amplitude and a signal type of the input signal supplied from the first connection terminal is converted, and activates the transmission line electrically coupled to the second connection terminal.
