摘要
A wireless device includes an impedance transforming network that couples an antenna to a Low Noise Amplifier (LNA) and includes at least one digitally controllable variable capacitor that may be adjusted to maximize an impedance transformation ratio on a desired channel. A tuned response centered on the desired channel provides attenuation to undesired channels.
