Abstract
A mixer has a controllable load, a signal mixing module, and a controller. The controllable load is controlled by a control signal to change an equivalent load value thereof. The signal mixing module has an output port coupled to the controllable load and an input port coupled to an input signal, and is used for mixing the input signal with a local oscillation signal. The controller is coupled to the controllable load, and is used for generating the control signal to reduce the equivalent load value of the controllable load during switching transients of the local oscillation signal.
