An apparatus includes first and second electronically tunable transmission lines configured to receive a signal pair and provide a selected phase delay difference to the signal pair, a first shunting element connected to the first electronically tunable transmission line and a second shunting element connected to the second electronically tunable transmission line. The first and second shunting elements may each be configured to selectively shunt the electronically tunable transmission line to which they are connected according to one or more shunting control signals. A corresponding method is also disclosed herein.
