Introduction

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.
