Resonator matching network
View Patent ↗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.
1. An input-matching network, comprising:
an oscillator;
an antenna; and
an acoustic resonator selected to provide impedance matching between the oscillator and the antenna, wherein the acoustic resonator provides a virtual inductance to match the impedance between the oscillator and the antenna.
2. An input-matching network as claimed in claim 1 , wherein the acoustic resonator is a film bulk acoustic (FBAR) resonator.
3. The input-matching network as claimed in claim 1 , wherein the acoustic resonator is a surface acoustic wave (SAW) resonator.
4. An input-matching network, comprising:
a transistor-amplifier;
an antenna; and
a film bulk acoustic resonator (FBAR) selected to provide impedance matching between the transistor amplifier and the antenna, wherein the acoustic resonator provides a virtual inductance to match the impedance between the transistor-amplifier and the antenna.
