STMICROELECTRONICS STPTIC-27L2C4

STPTIC-27L2C4 is a 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 capacitor is a tunable capacitor intended for use in mobile phone application and dedicated to RF tunable applications. This tunable capacitor is controlled through an extended bias voltage ranging from 1 to 24V. The implementation of BST tunable capacitor in mobile phones enables significant improvement in terms of radiated performance making the performance almost insensitive to the external environment. Typical applications include Cellular antenna open loop tunable matching network in multi-band GSM/WCDMA/LTE mobile phone, open loop tunable RF filters.
