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. Most importantly,

the F1912 includes Renesas’ Glitch-FreeTM

technology, which results in low overshoot and

ringing during MSB transitions.

■

Glitch-FreeTM technology so PA or ADC will not

be damaged during when transitions.

■

Extremely accurate with low distortion.

■

Lowest insertion loss for best SNR
