Product Overview

The RFMD’s RFSA3413 is a 4-bit digital step

attenuator (DSA) that features high linearity over

the entire 15dB gain control range with 1.0dB steps.

The RFSA3413 uses parallel control interface.

The RFSA3413 has a low insertion loss of 1.4dB at

2GHz. Patent pending circuit architecture provides

overshoot-free transient switching performance.

The RFSA3413 is available in a 3mm x 3mm QFN

package.
