A wireless apparatus for determining a phase difference of a received RF signal, and method. The apparatus includes antennas displaced from each other by a predetermined distance for receiving an RF signal. The apparatus also includes an exclusive OR (EXOR) circuit comparing binary signals derived from the received RF signal that are associated with respective antennas. An absolute phase difference is based on a pulse width of the comparison.
