Datasheet - production data
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 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.
