Abstract
In accordance with an embodiment, a system includes a switchable resistive element configured to be coupled to an input of an RF amplifier, and a switchable capacitive element having a first terminal configured to be coupled between the switchable resistive element and inductive element coupled to a system input. The switchable capacitive element is configured to reduce a first impedance of the inductive element to a second impedance lower than the first impedance during a first operation mode; the switchable resistive element is configured to reduce an input impedance of the RF amplifier to a third impedance lower than the input impedance of the RF amplifier during the first operation mode; and the switchable capacitive element and the switchable resistive element are configured to provide a first attenuation to an RF signal provided at the system input during the first operation mode.
