Smart-Antenna Controller from STMicroelectronics Cuts Board Space, BoM, and Battery Load for Superior Smartphone Performance
(WorldNews Switzerland)

Geneva / 16 Jan 2019 STMicroelectronics` STHVDAC-253C7 digital controller for tunable capacitors such as ST`s STPTIC family shrinks the size, bill of materials (BoM), and power consumption of antenna-tuning circuits for stabilizing smartphone RF performance. Using the STHVDAC-253C7 with STPTIC capacitors for impedance matching and frequency tuning almost completely eliminates the effects of environmental variations,...
