Abstract
A phase shifter having a four port hybrid coupler is provided. The four port hybrid coupler has first and second input ports and first and second output ports. The four port hybrid coupler is configured to shift the phase of an RF signal as between the first and second input ports. First and second active semiconductor devices are connected to first and second output ports. The first and second active semiconductor devices are configured to change the phase shift of the RF signal as between the first and second input ports based upon a varying voltage.
