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 capacitances are tunable capacitances
intended for use in mobile phone application, and
dedicated to RF tunable applications. These
tunable capacitances are controlled through a
bias voltage ranging from 2 to 20 V. The use of
BST tunable capacitance in mobile phones
enables significant improvement in terms of
radiated performances making the performance
almost insensitive to the external environment.
