New RF tunable capacitors boost LTE smartphone performance
ST’s new range of BST (barium strontium titanate) tunable capacitors in a WLCSP package uses solder bars instead of bumps. In addition to increasing the chip’s mechanical strength when soldered on thin printed circuit boards, the 3-solder bar package is smaller than a 4-bump device, making this new C4 series of Parascan™ tunable integrated capacitors (STPTIC) even more suited for high-volume manufacturing.
There are currently three RF tunable capacitors with solder bars: STPTIC-15C4 and STPTIC-27C4 are high-linearity devices used in frequency-tuning applications and the STPTIC-82C4 with standard linearity is best suited for impedance matching. A common land pattern can be used in order to support passive tunable integrated circuit (PTIC) values ranging from 1.5 to 8.2 pF.
