Patent ID: 10312861

Abstract:
An apparatus and method are provided. The apparatus includes a multiplexer, including first, second, and third inputs, and an output; a first transistor, including a gate connected to the multiplexer, and first and second terminals; a first variable capacitor, including a first terminal connected to the first transistor, a second terminal, and an input; a first inductor, including a first terminal connected to the first transistor, and a second terminal connected to the second terminal of the first variable capacitor; a second transistor, including a gate connected to the output of the multiplexer, a first terminal, and a second terminal connected to the second terminal of the first inductor; a second inductor mutually coupled to the first inductor, including a first and second terminals; and a balun-bias switch, including first, second, and third inputs, and an output connected to the second terminal of the second inductor.
