Abstract
A balanced amplifier can utilize a common mode choke to suppress even harmonics in the signals of the balanced amplifier. The common choke can be coupled between cascaded balanced amplifier pairs to receive the differential output signals from one of the balanced amplifier pairs and to provide conditioned signals to the other of the balanced amplifier pairs. The common mode choke can improve the amplitude and phase balance between the differential output signals by providing increased impedance to the passage of common mode signals such as even harmonics.
