RFSA3613数据手册Qorvo中文资料规格书

描述 Description

Qorvo's RFSA3613 is a 6-bit digital step attenuator (DSA) that features high linearity over the entire 31.5dB gain control range with 0.5dB steps. The RFSA3613 uses serial control interface. The RFSA3613 has a low insertion loss of 1.4dB at 2GHz. Patent pending circuit architecture provides overshoot-free transient switching performance. External addres pins allow up to eight DSAs to be controlled on a single bus. The RFSA3613 is avaiable in a 3mm x 3mm QFN package.
