RFMW Ltd. announces design and sales support for a digital step attenuator (DSA). The Qorvo RFSA3523 offers 5-bits of attenuation with 0.5 dB LSB step size providing 15.5 dB of attenuation range from 5 to 6000 MHz.

Featuring overshoot-free transient switching between attenuation steps, the RFSA3523 is ideal for wireless infrastructure, military radio, land mobile radio and access points. High linearity (IIP3 >55 dBm), fast switching speed of 120 nS and low insertion loss of 1.4 dB typify performance. SOI technology improves robustness and allows on-board logic control for serial interface.

Qorvo offers this DSA in a 3 x 3 mm QFN package.
