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.
