1. A switching circuit, comprising:
a first transmission amplifier, coupled between a first connection port and a second connection port;
a second transmission amplifier, coupled between a third connection port and a fourth connection port;
a third transmission amplifier, coupled between the first connection port and the fourth connection port; and
a fourth transmission amplifier, coupled between the second connection port and the third connection port,
wherein in a first mode among a plurality of modes, the first transmission amplifier amplifies a first signal at the first connection port and transmits the first signal to the second connection port, and the second transmission amplifier amplifies a second signal at the third connection port and transmits the second signal to the fourth connection port,
wherein in a second mode among the modes, the third transmission amplifier amplifies the first signal at the first connection port and transmits the first signal to the fourth connection port, and the fourth transmission amplifier amplifies the second signal at the third connection port and transmits the second signal to the second connection port.
