Abstract
A radio frequency (RF) device and a multi-band matching circuit thereof are provided. The multi-band matching circuit includes an inductance circuit, a first capacitance circuit, an inductor, and a second capacitance circuit. A first terminal of the inductance circuit is coupled to a RF signal input terminal of the multi-band matching circuit. A first terminal of the first capacitance circuit is coupled to a second terminal of the inductance circuit. A first terminal of the inductor and a first terminal of the second capacitance circuit are coupled to a second terminal of the first capacitance circuit. A second terminal of the inductor is coupled to a first reference voltage. A second terminal of the second capacitance circuit is coupled to a second reference voltage. The second capacitance circuit is controlled by a single-bit control signal to change a capacitance value of the second capacitance circuit.
