The ST BST capacitance controller STHVDAC-303 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 capacitances.
It provides 3 independent high voltage outputs, thus having the capability to control 3 different capacitances in parallel. It is fully controlled through a 3-wire serial interface.
BST capacitances are tunable capacitances intended for use in mobile phone application, and dedicated to RF tunable applications. These tunable capacitances are controlled through a bias voltage ranging from 0 to 30 V. The implementation of BST tunable capacitance in mobile phones enables significant improvement in terms of radiated performance, making the performance almost insensitive to the external environment.
