Abstract
A quadrature divider includes a first analog mixer (20, 30) for receiving a digital input signal at a predetermined frequency at a first input of the mixer and a second analog mixer (24, 32) for receiving the input signal with a 180° phase shift at a first input of the mixer. The output of the first mixer is coupled to a second input of the first mixer and an output of the second mixer is coupled to a second input of the second mixer.
