More Information
Summary:Disclosed is a low noise amplifier system (10). Included is a main amplifier (24) having a main input coupled to a RF input and a main output connected to an RF output and an impedance amplifier (12) having an impedance input coupled to the RF input and an impedance output coupled to the RF output, wherein the impedance amplifier (12) is configured to provide input impedance matching to the main amplifier (24). The impedance amplifier (12) also provides a first noise path that passes through the impedance amplifier (12) such that the noise generated by the impedance amplifier (12) is substantially out of phase with the noise that passes through a second noise path that passes through the main amplifier (24).
