Classification: CPC H | IPC H

Claim 1:
2. The directional coupler according to claim 1, wherein the first amplifier circuit either outputs a current directly proportional to the first voltage by amplifying the first voltage at a first amplification factor, or outputs a current directly proportional to the second voltage by amplifying the second voltage at the first amplification factor, and the second amplifier circuit outputs the first current directly proportional to the voltage difference between the first voltage and the second voltage by amplifying the voltage difference at a second amplification factor when a signal is flowing from the first terminal to the second terminal, whereas the second amplifier circuit outputs the second current directly proportional to the voltage difference by amplifying the voltage difference at the second amplification factor when a signal is flowing from the second terminal to the first terminal.
