| Zusammenfassung: | A signal amplifier includes a band suppression filter configured to suppress a preset band among bands included in an input signal, a first common source-type amplifier connected between a supply terminal of a driving voltage and a ground terminal and configured to amplify a first input signal separated from an output signal of the band suppression filter in a common input node to provide a first amplified signal to a common output node, a second common source-type amplifier configured to amplify a second input signal separated from the output signal of the band suppression filter in the common input node to provide a second amplified signal to the common output node, and an output matcher configured to match levels of impedance between the common output node and an output terminal and to transfer a combined signal to the output terminal. |
