6-bit Digital Step Attenuator 400 to 4000 MHz F1953 Datasheet GENERAL DESCRIPTION This document describes the specification for the IDTF1953 Digital Step Attenuator. The F1953 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. COMPETITIVE ADVANTAGE Digital step attenuators are used in Receivers and Transmitters to provide gain control. The IDTF1953 is a 6-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (> +60 dBm IP3I.) The device has pinpoint accuracy and settles to final attenuation value within 400 ns.
