Abstract: A power amplifier comprising a first transistor pair and a first odd mode resistor string. The first transistor pair has a first transistor and a second transistor. A first end of the first transistor is symmetrically disposed to a first end of the second transistor. A plurality of first odd mode resistors are serially coupled between the first end of the first transistor and the first end of the second transistor. A total length of the first odd mode resistor string is substantially equal to a distance between the first end of the first transistor and the first end of the second transistor.

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.
