ST’s tunable capacitors and associated controllers are designed to tune wireless antennas to specific frequencies. The implementation of tunable capacitors enables significant improvement in terms of radiated performance (TRP & TIS) making them almost insensitive to the external environment.

ST’s integrated tunable capacitors offer excellent RF performance, low power consumption and high linearity required in adaptive RF tuning applications:

The fundamental building block of a passive tunable integrated circuit (PTIC) is a tunable material called Parascan™, which is a version of barium strontium titanate (BST) developed by Paratek microwave.
