Abstract
A multiple-path, configurable, radio-frequency (RF) circuit is provided, including: a first amplifier path amplify a first RF signal to generate a first amplified signal; a second amplifier path configured to amplify a second RF signal to generate a second amplified signal; a corrective input matching circuit, configured to change first input-impedance-matching properties of the first amplifier path, and to change second input-impedance-matching properties of the second amplifier path; a first isolation element configured to selectively ground an input node of the second amplifier path; a second isolation element configured to selectively ground an output node of the second amplifier path; and a third isolation element connected between the first and second amplifier paths, configured to selectively isolate the corrective input matching circuit from first and second input nodes of the first and second amplifier paths, respectively, or connect the corrective input matching circuit to the first and second input nodes.
