Fully I/Q balanced quadrature radio frequency mixer with low noise and low conversion loss

摘要

Methods, apparatus, and system products for mixing radio frequency signals are provided. In one aspect, the apparatus is configured to perform switch switching based on half-duty clock signals of first, second, third, and fourth phases. The device convolves the differential input signal on the differential input port with the first, second, third and fourth phase half-duty cycle clock signals to provide a differential common-mode output on the dual differential output port A signal and a differential quadrature output signal are generated simultaneously. The first, second, third and fourth phase half duty cycle clock signals have the same frequency and are out of phase by a multiple of 90 degrees relative to each other.
