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 6-

bit 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. Most importantly, the F1951 includes

Renesas’

Glitch-FreeTM technology which results in less

than 0.6 dB of overshoot ringing during MSB transitions.

This is in stark contrast to competing DSAs that

glitch as

much as 10 dB during MSB transitions (see p.10).



Lowest insertion loss for best SNR



Glitch-FreeTM when transitioning –

won’t damage PA or ADC



Extremely accurate with low distortion
