DESCRIPTION
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 capacitors in mobile phones enables significant improvement in terms of radiated performance making the performance almost insensitive to the external environment.
