BST Varactors for Tunable RF Circuits

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review

Abstract

This paper presents VTT's ferroelectric BST- varactor technology applicable to tunable components and circuits. As an example, a tunable stub resonator was designed, fabricated and characterized. A 40% capacitance tuning range results into a 25% shift in stub resonator frequency. A tuning voltage from zero DC bias to 40V results to a center frequency shift from 4.5 to 5.9 GHz.
