Abstract :
Barium strontium titanate Ba/sub 0.6/Sr/sub 0.4/TiO/sub 3/ thin-film based tunable coplanar waveguide (CPW) components were studied in this research. The CPW components modeled and experimentally verified include CPW transmission lines, resonators and 2-pole filters. The resonators and filters fabricated and tested exhibited a frequency tunability of approximately 3% for a bipolar bias voltage of /spl plusmn/100 V, corresponding to a peak biasing field of 40 kV/cm.
