RFAC3612 Datasheet, PDF (1/15 Pages) RF Micro Devices – 3 Wire SPI Compatible Control

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.
