Abstract
A radio frequency (RF) signal separation and suppression system includes an input that couples in a radio frequency signal comprising desired and undesired radio frequency signals. The RF signal separation and suppression system also includes a reproduction generator connected to the input. The reproduction generator produces a reproduction from the radio frequency signal of the undesired signal at an output. The RF signal separation and suppression system also includes an electrical subtractor having a first input that is electrically connected to the output of the reproduction generator and a second input that is electrically connected to the input of the radio frequency signal separation system. An output of the subtractor generates an output radio frequency signal comprising the desired radio frequency signal and a suppressed undesired radio frequency signal.
