The STPTIC-27C4 fundamental building block of PTIC is a tunable material called Parascan, which is a version of barium strontium titanate (BST) developed by Paratek microwave. BST capacitors are tunable capacitors intended for use in mobile phone application and dedicated to RF tunable applications. These tunable capacitors are controlled through an extended bias voltage ranging from 1 to 24 V. The implementation of BST tunable capacitor in mobile phones enables significant improvement in terms of radiated performance making the performance almost insensitive to the external environment.
