Tunable Capacitor for Adaptive RF Tuning Applications

Tunable Capacitor for Adaptive RF Tuning Applications

STMicroelectronics’ STPTIC-15L2C4 tunable integrated capacitor offers high performance, low-power consumption, and high-linearity required in adaptive RF tuning applications. This component includes the Parascan tunable material, which is a version of barium strontium titanate (BST) developed by Paratek Microwave Inc. These capacitors are controlled through an extended bias voltage ranging from 1V to 24V and are available in WLCSP packages. They feature low-leakage current and are compatible with high-voltage control ICs (STHVDAC series). Typical applications include multiband mobile phones and open loop tunable RF filters.
