Abstract: 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.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating a two-tone signal for performing linearity calibration of a radio frequency (RF) circuit. One example apparatus generally includes a tone generating circuit configured to generate a first single-tone signal from a digital clock signal and a mixer connected with the tone generating circuit and configured to mix the first single-tone signal with a second single-tone signal to provide a two-tone signal having frequencies at a sum and a difference of frequencies of the first and second single-tone signals.
