Abstract
A device for conditioning a signal includes a hybrid phase shifter and power divider. The power divider circuit includes a transmission line with an input port and two asymmetrical output ports, a first ground plane, a second ground plane, and a first dielectric region. The variable phase shifter includes the transmission line and a dielectric slab disposed to be variably positioned in the first dielectric region. The position of the dielectric slab in relation to the power divider circuit determines the amount of phase shift in the signal. With the above configuration, the invention requires much less space and reduces the number of parts and cable interconnects.
