Abstract:
1. A multiple-path, configurable, radio-frequency (RF) circuit, comprising: a first amplifier path configured to match a first input impedance of a first RF input signal to generate a first input-impedance-matched signal, amplify the first input-impedance-matched signal by a first amplification factor to generate a first amplified signal, and match a first output impedance of the first amplified signal to generate a first output-impedance-matched signal; a second amplifier path configured to match a second input impedance of a second RF input signal to generate a second input-impedance-matched signal, amplify the second input-impedance-matched signal by a second amplification factor to generate a second amplified signal, and match a second output impedance of the second amplified signal to generate a second output-impedance-matched signal; a first 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 isolate an output node of the second amplifier path; and a third isolation element connected between the first corrective input matching circuit and first and second input nodes of the first and second amplifier paths, respectively, configured to selectively isolate the first corrective input matching circuit from the first and second input nodes or connect the first corrective input matching circuit to the first and second input nodes.
