The ST high voltage BST capacitor controller STHVDAC-253MTG is a high voltage digital to analog converter (DAC), specifically designed to control and meet the wide tuning bias voltage requirement of the BST tunable capacitors.
It provides 3 independent high voltage outputs, thus having the capability to control 3 different capacitors. It is fully controlled through an RFFE serial interface.
BST capacitors are tunable capacitors intended for use in mobile phone application, and dedicated to RF tunable application. These tunable capacitors are controlled through a bias voltage ranging from 0 to 24 V. The implementation of BST tunable capacitor in mobile phones enables significant improvement in term of radiated performance, making the performance almost insensitive to external environment.
