F1956NBGI8
DESCRIPTION
This document describes the specification for the F1956 Digital Step Attenuator. The F1956 is part of Renesas’ Glitch-Free TM family of DSAs optimized for the demanding requirements of Base Station (BTS) radio cards and numerous other non-BTS applications. This device is offered in pact 5 × 5 mm 32-pin package with 50Ω input and output impedance for ease of integration into the radio or RF system.
PETITIVE ADVANTAGE
The F1956 offers very high reliability due to its construction from a monolithic silicon die in a QFN package. The insertion loss is very low with minimal distortion. Additionally, the device is designed to have extremely accurate attenuations levels. These accurate attenuation level improves system SNR and/or ACLR by ensuring system gain is as close to targeted level as possible. Also, the very fast settling time in parallel mode is ideal for fast switching systems. Finally, the device is Glitch-Free TM with less than 2d B of ringing across the attenuation range...
