A FULLY I/Q BALANCED QUADRATURE RADIO FREQUENCY MIXER WITH LOW NOISE AND LOW CONVERSION LOSS

A method, an apparatus, and a system product for mixing radio frequency signals are provided. In one aspect, the apparatus is configured to perform switching of switches based on first, second, third, and fourth phased half duty clock signals. The apparatus convolves a differential input signal on a differential input port with the first, second, third, and fourth phased half duty cycle clock signals to concurrently generate a differential in-phase output signal and a differential quadrature-phase output signal on a dual differential output port. The first, second, third, and fourth phased half duty cycle clock signals are of the same frequency and out of phase by a multiple of ninety degrees with respect to each other.
