    Qorvo's RFAC3612 is a 6-bit, 64-state PAC (Programmable Array of Capacitors) for tunable RF applications. The RFAC3612 is optimized for series configuration but can also be applied in shunt configuration. The high power handling, high Q and excellent linearity makes it ideal for use in antenna tuning, tunable filters and tunable matching networks.

    The part includes an integrated LDO (Low Drop Out) regulator, which enables operation from a very wide supply range from 2.4V to 3.5V. The state of the RFAC3612 PAC is controlled by a 3 wire SPI compatible interface. All pins are ESD protected to ensure 2kV HBM ESD tolerance. RFAC3612 is packaged in a very compact 2.0mm x 2.5mm, 10-pin package.
