RFMD’s RFSA2644 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 RFSA2644 is programmed via a serial mode control interface that is  
both 3V and 5V compatible. The RFSA2644 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.
