摘要：

The tunability and dielectric losses of ferroelectric (Ba,Sr)TiO3 film varactors were measured under DC voltage at microwave frequencies (similar to 20GHz), A new microwave two-pole tunable waveguide filler containing four ferroelectric (Ba,Sr)TiO3 film varactors was designed and tested. The frequency tuning of the filter results from the variation in capacitance of ferroelectric varactors with DC controlling voltage.
