Patent abstract
Disclosed is an impedance matching apparatus performing impedance matching between a front-end module and an antenna. The impedance matching apparatus includes an RF front end providing a multi-band RF signal, a reflected power measuring module measuring a reflection coefficient for the RF input signal, a matching unit adjusting impedance so that the reflection coefficient is minimized, a first switch module provided in the RF front end to selectively switch the RF signal onto a bypass path, and a controller allowing the RF signal to be switched onto the bypass path if a specific frequency range is detected from the reflection coefficient.
