STPTIC-39L2H5 数据手册 ( 数据表 ) - STMicroelectronics

Description
The ST integrated tunable capacitor offers excellent RF performance, low power consumption and high linearity required in adaptive RF tuning applications. The 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 capacitors in mobile phones enables significant improvement in terms of radiated performance making the performance almost insensitive to the external environment.
