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

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 capacitor in

mobile phones enables significant improvement

in terms of radiated performance making the

performance almost insensitive to the external

environment.
