Abstract

The present invention provides a transmitter including a mixer, a harmonic impedance adjustment circuit and an amplifier. The mixer is configured to mix a first baseband signal with a first oscillation signal to generate a first mixed signal to a first node, and to mix a second baseband signal with a second oscillation signal to generate a second mixed signal to a second node. The harmonic impedance adjustment circuit is coupled between the first node and the second node, and is configured to reduce harmonic components of the first mixed signal and the second mixed signal to generate an adjusted first mixed signal and an adjusted second mixed signal. The amplifier is coupled to the harmonic impedance adjustment circuit, and is configured to generate an amplified signal according to the adjusted first mixed signal and the adjusted second mixed signal.
