Abstract: A method includes receiving a radio frequency (RF) input signal using at least one non-reciprocal circulator. The method also includes generating an RF output signal using at least one of multiple reflective filter elements. Each reflective filter element is configured to receive an RF signal from the at least one non-reciprocal circulator and to provide a filtered RF signal to the at least one non-reciprocal circulator. The reflective filter elements include amplitude change reflectors configured to modify amplitudes of the RF signal at different frequencies. The RF output signal represents the RF input signal as modified by the at least one of the reflective filter elements.

Abstract: A method and receiver for detecting a signal wherein the signal is encoded the signal with a pair of spaced predetermined frequencies and wherein energy is detected in each of the pair of predetermined frequencies and in a predetermined frequency between the pair of predetermined frequencies. Energy detected in each of the pair of predetermined frequencies is compared with the energy detected in the predetermined frequency between the pair of predetermined frequencies. The detecting includes passing the encoded signal through narrow band filters, each one of the filters being tuned to a corresponding one of the pair of predetermined frequencies and the predetermined frequency between the pair of predetermined frequencies.
