An alternative to PSMI Digitally Tunable Capacitors (DTC). See psemi.com Other Chips (cont.) We had one of our readers spot another really good chip story, and one that perhaps helps to differentiate Blackberry in terms of their vertical integration and wireless capabilities. There are three impedance matched BST (Barium Strontium Titanate) IC’s that were developed by a company called Paratek, which was acquired by RIM in March 2012 (the orange devices at right). They play a key role in tuning the antenna. One of the investors in Paratek calls the solution a. “game changer by allowing users to upload data faster and experience fewer dropped calls.” The BST devices allow for the antenna tuning to be optimized depending upon conditions, thus making them adaptive. Voltages to the BST tuner IC’s are modified to maximize tuner efficiency, thus saving power and reducing dropped calls. chipworks.com
