Product Description
RFMD’s RFSA2624 is a 6-bit Digital Step Attenuator (DSA) that features high linear-
ity over the entire 31.5dB gain control range with excellent step accuracy in 0.5dB
steps. The RFSA2624 is programmed via a serial mode control interface that is
both 3V and 5V compatible. The RFSA2624 also offers a rugged Class 1B HBM
ESD rating via on-chip ESD circuitry. The MCM package is footprint compatible with
most 24-pin, 4mm, QFN packages.
