F1912 6-Bit Digital Step Attenuator, 1MHz to 4000MHz Datasheet This document describes the specification for the Renesas F1912 Digital Step Attenuator. The F1912 is part of a family of Glitch-FreeTM DSAs optimized for the demanding requirements of Base Station (BTS) radio cards and numerous other non-BTS applications. These devices are offered in a compact 4mm x 4mm 20-pin QFN package with 50Ω impedances for ease of integration. Competitive Advantage Digital step attenuators are used in receivers and transmitters to provide gain control. The F1912 is a 6-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (> +60 dBm IIP3). The device has pinpoint accuracy.
