A variable power divider is disclosed, which comprises: a phase shifter with an input port for receiving an RF signal, a phase shifter transmission path segment connecting two phase shifter output ports, and a moveable electrical path creating a signal path between the input port and the phase shifter output ports. The moveable electrical path is configured to move throughout an adjustment and along the phase shifter transmission path to cause complementary adjustment of electrical signal path lengths between the input port and the two phase shifter output ports. The two phase shifter output ports are configured to output two variable complementary phase RF signals as the moveable electrical path is moved throughout the adjustment range. Also included is a hybrid power divider which includes a first power divider input port connected to the first phase shifter output port, a second power divider input port connected to the second phase shifter output port, and two power divider output ports for outputting two RF signals having variable and complementary power amplitudes, as the moveable electrical path is moved throughout the adjustment range. A capacitive junction is included in the signal path between the moveable electrical path and the phase shifter transmission path.
