Abstract: An object of the present invention is to realize a loop through circuit, in an active connector, securely having a preferable mismatching attenuation characteristic and having a preferable signal transmission characteristic, with respect to an input port, an output port, and an internal port, without providing a special circuit outside the connector. A connector base part has the input port inputting an external signal, the output port outputting a loop through signal, and the internal port outputting a signal into a device. First and second matching circuits, an equalizer circuit, a dividing circuit, and a driving circuit are stored in the connector base part. The matching circuit is supplied with an external signal input from the input port. The dividing circuit divides a signal to be input to generate first and second divided signals, and outputs them to the internal port and the output port. The equalizer circuit compensates for a frequency characteristic and/or loss of a signal to be input.

Abstract: An active connector is provided that allows for simple designing of devices for high-speed wideband pulse signal transmission without specialized technical know-how in the use of connectors. A connector base has a first connection terminal and a second connection terminal, and houses a first matching circuit, a second matching circuit, and a buffer circuit. The first connection terminal and the second connection terminal can be used as an internal port electrically coupled to a device circuit and an external port electrically coupled to a transmission line, respectively. An input signal inputted into the first connection terminal is supplied to the first matching circuit. The second matching circuit supplies an output signal to the second connection terminal. A buffer circuit between the first matching circuit and the second matching circuit inhibits mutual influences between the input signal and the output signal.
