STHVDAC-253MTG Antenna tuning circuit with turbo and glide Datasheet - production data Description 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. /HDG IUHH )OLS &KLS BST capacitors are tunable capacitors intended EXPSV for use in mobile phone application, and dedicated to RF tunable application. These tunable capacitors are controlled through a bias Features voltage ranging from 0 to 24 V. The Dedicated controller to bias BST tunable implementation of BST tunable capacitor in mobile phones enables significant improvement capacitors in term of radiated performance, making the Operation compliant with cellular systems performance almost insensitive to external requirements environment. Turbo and glide modes for optimal system performance Figure 1.
