An input-matching network including an acoustic resonator providing a virtual impedance to match impedance between a first component and second component. As an example, the first component may be an antenna and the second component may be an amplifier. The acoustic resonator provides a virtual impedance to match impedance between the antenna and the amplifier. The acoustic resonator may be, for example, a film bulk acoustic (fbar) resonator or a surface acoustic wave (saw) resonator.
