ST’s STPTIC devices form a series of tunable RF capacitors. These tunable capacitors are intended for use in mobile phone applications, dedicated to RF tunable applications.
ST’s STPTIC series features standard capacitor values ranging from 2.7 pF to 8.2 pF. These tunable capacitances are controlled through a bias voltage ranging from 2 to 20 V, with a tuning ratio of 3.5 to 1.
ST’s tunable capacitors are available in flip-chip and micro QFN packages.
ST takes up the challenge of a 5 to 1 tuning ratio with its STPTIC G2 series
They are housed in a 4-bump 0.4-mm-pitch flip-chip package and are initially available as evaluation samples in 1.5pF (nom) STPTIC-15G2, 3.9pF (nom) STPTIC-39G2 and 6.8 pF (nom) STPTIC-68G2 versions.
