Description
Summary:A compact continuously tunable phase shifter is presented employing integrated ferroelectric varactors based on screen printed BST thick film. The circuit is based on left handed transmission line topology that allows to considerably reduce the module size. The proposed design has a total length of 1.3mm and provides a differential phase shift up to 330°. Furthermore, the phase shifter is in coplanar strip configuration which makes it suitable for systems consisting of balanced components.
