ABSTRACT:
A method and amplifier circuit (20) for conditioning a signal. The amplifier circuit (20) includes a field effect transistor (22) having a sub-harmonic termination (21) connected to a drain of the field effect transistor (22). In addition, an output impedance termination (24) is connected to the drain of the field effect transistor (22) and an input impedance termination (23) is connected to the gate of the field effect transistor (22). The sub-harmonic termination (21) reduces a non-linear component of an interference signal.
