DESCRIPTION This document describes the specification for the F1951 Digital Step Attenuator. The F1951 is part of a family of Glitch-FreeTM DSAs optimized for the demanding requirements of communications Infrastructure. These devices are offered in a compact 4x4 QFN package with 50 Ω impedances for ease of integration into the radio system. COMPETITIVE ADVANTAGE Digital step attenuators are used in Receivers and Transmitters to provide gain control. The F1951 is a 6bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (+65 dBm IP3I.). The device has pinpoint accuracy and settles to final attenuation value within 400 nsec.
