RFSA2514 Serial Controlled Digital Step Attenuator 50MHz to 4000MHz, 5-Bit, 0.5dB LSB

RFMD's RFSA2514 is a 5-bit digital step attenuator (DSA) that features high linearity over the entire 15.5dB gain control range with excellent step accuracy in 0.5dB steps. The RFSA2514 is programmed via a serial mode control interface that is both 3V and 5V compatible. The RFSA2514 also offers a rugged Class 1C HBM ESD rating via on-chip ESD circuitry. The MCM package is footprint compatible with most 24-pin, 4mm x 4mm, QFN packages.
