Abstract: A switching circuit and a method of providing the switching circuit are provided. The switching circuit includes a first transmission amplifier, a second transmission amplifier, a third transmission amplifier, and a fourth transmission amplifier. The first transmission amplifier amplifies a first signal at a first connection port and transmits the first signal to a second connection port in a first mode. The second transmission amplifier amplifies a second signal at a third connection port and transmits the second signal to a fourth connection port in the first mode. The third transmission amplifier amplifies the first signal at the first connection port and transmits the first signal to the fourth connection port in the second mode. The fourth transmission amplifier amplifies the second signal at the third connection port and transmits the second signal to the second connection port in the second mode.
