To achieve an economic advantage, nanocrystalline Ba 0.5 Sr 0.5 TiO 3 (BST) thin films
were prepared on FTO-coated glass substrates using an aqueous sol–gel process. The …

In this article, a novel study of the design and characterization of barium strontium titanate
(BST) thick films produced by electrophoretic deposition (EPD) on flexible platinum foils is …

New methods for the design of tunable combline bandpass and bandstop filters are
presented. The first part of this paper presents a tunable bandstop filter designed using a …

This study presents a direct comparison between semiconductor and barium strontium
titanate (BST) tuning technologies. Tapped line combline two-pole and four-pole bandpass …

A novel electronically reconfigurable microwave bandpass filter based on a switched delay-
line approach is presented. In contrast to conventional tunable filters, the approach enables …

This letter presents a three-pole tunable Ka-band coplanar filter that includes six high-Q BST
ferroelectric capacitors. It tunes from 29 GHz up to 34 GHz (17%) with low bias voltages …

<? Pub Dtl=""?> Two two-pole X-band-tunable ferroelectric filters with constant fractional
bandwidths and constant return losses are presented in this paper. The center frequency …

This paper presents two 3-pole tunable bandpass coplanar filters that include BST
ferroelectric capacitors, tunable from 28 GHz up to 37 GHz. Both filters consist of cascaded …

A microwave characterization of (Ba, Sr) TiO 3 (BST) thin films of different thickness has
been carried out by means of a fully comprehensive equivalent circuit applied to …

This paper presents tunable filters and phase shifters using low-loss ferroelectric BST
(Barium Strontium Titanate) capacitors. Optimization of the BST varactors has resulted in …
