A Low Voltage Tunable Analog Phase Shifter Utilizing Ferroelectric Varactors
Integrated Ferroelectrics: An International Journal
A distributed transmission line phase shifter was implemented by periodically loading a coplanar transmission line using ferroelectric varactors in a shunt configuration. A single dc bias applied to the phase shifter circuit provides a large relative phase shift. A relative phase shift of ∼ 305 degrees was obtained at 20 GHz for a dc bias of only 5 V.
