STPTIC Parascan tunable integrated capacitor Datasheet - production data Applications Cellular Antenna open loop tunable matching network in multi-band GSM/WCDMA/LTE mobile phone Open loop tunable RF filters Description QFN Flip Chip 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 Features Parascan, which is a version of barium strontium titanate (BST) developed by Paratek microwave. High power capability (+36 dBm) BST capacitances are tunable capacitances High tuning range (3.5/1) intended for use in mobile phone application, and High quality factor (Q) dedicated to RF tunable applications. These High linearity device tunable capacitances are controlled through a bias voltage ranging from 2 to 20 V. The use of Low leakage current BST tunable capacitance in mobile phones Capacitor bias is DC blocked enables significant improvement in terms of Frequency of operation from DC to 3 GHz radiated performances making the performance almost insensitive to the external environment. 8 values available: 1.2 pF, 2.7 pF, 3.3 pF, 3.9 pF, 4.7 pF, 5.6 pF, 6.8 pF and 8.2 pF Analog control voltage Compatible with high voltage control IC (STHVDAC series) Available in plastic molded package: QFN package 1.2 x 1.6 x 0.9 mm Flip Chip 0.65 x 1.0 x 0.3 mm Flip Chip 0.65 x 1.2 x 0.3 mm ECOPACK 2 compliant component Benefit RF tunable passive implementation in mobile TM: Parascan is a trade mark of Paratek microwave Inc. phones to optimize antenna radiated performances.
