The present invention is an apparatus for shifting the phase of an radiofrequency signal. The device has an input line and an output line. An input switch is connected to the input line. The input switch is has several input throws. An output switch is connected to the output line. The output switch has several output throws which correspond to the input throws. The apparatus also has several phase shift lines. Each phase shift line has a true path length that is different from the true path lengths of the other phase shift lines.
