Abstract
The present invention provides a phase shift circuit that supports multiple frequency ranges. The phase shift circuit receives a plurality of control bits and causes a phase shift in a received signal, the phase shift corresponding to a number of time steps, the number depending on the control bits, and the time step is selected from a plurality of different time steps based on a frequency range associated with the received signal.
