RFSA2534SQ Overview

50MHz to 4000MHz, Digital Step Attenuator

RFSA2534
50MHz to 4000MHz, Digital Step Attenuator
RFMD’s RFSA2534 is a 5-bit digital step attenuator (DSA) that
features high linearity over the entire 15.5dB gain control range
with 0.5dB steps. The RFSA2534 uses serial control interface. It
has a low insertion loss of 1.3dB at 2GHz. Patent pending circuit
architecture provides Overshoot-free transient switching
performance The RFSA2534 is available in a 4.2mm x 4.2mm
laminate package that is footprint compatible with a 4mm x 4mm
QFN 24 lead package.
