描述 Description

Qorvo's RFSA3623 is a 6-bit digital step attenuator (DSA) that features high linearity over the entire 15.75dB gain control range with 0.25dB steps. The RFSA3623 uses serial control interface. The RFSA3623 has a low insertion loss of 1.4dB at 2GHz. Patent pending circuit architecture provides overshoot-free transient switching performance. External address pins allow up to eight DSAs to be controlled on a single bus. The RFSA3623 is available in a 3mm x 3mm QFN package.
