RFAC3612

6-Bit, PAC (Programmable Array of Capacitors)

The 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 RFAC3612 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.
