ABSTRACT:
A phase shifter transmission line includes a semiconductor layer 20; a first conductor region 42 on the semiconductor layer 20; a first doped region 24 and 30 in the semiconductor layer adjacent the first conductor region; and a variable bias voltage coupled to the first conductor region 42 for varying an effective dielectric constant in the transmission line.
