Abstract
A system includes at least a first array connected to a second array. The first array includes an odd number, greater than one, of unidirectionally-coupled non-linear first array elements. The second array includes an odd number, greater than one, of unidirectionally-coupled non-linear second array elements. The second array elements are unidirectionally-coupled in a direction opposite the coupling direction of the second array elements. The first array is configured to receive an input signal and down-convert the input signal. The second array is configured to receive the down-converted input signal, further down-convert the down-converted input signal, and output a down-converted output signal. The down-converted output signal is down-converted to a multiple of the frequency of the input signal proportional to the number of arrays of the system. The system may operate at frequencies greater than 1 GHz and may be contained in a microchip or on a printed circuit board.
