RFMW, Ltd. announces design and sales support for a Digital Step Attenuator (DSA). The Qorvo RFSA3523 offers 5-bits of attenuation with 0.5dB LSB step size providing 15.5dB of attenuation range from 5 to 6000MHz. 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 >55dBm), fast switching speed of 120nS and low insertion loss of 1.4dB typify performance. SOI technology improves robustness and allows on-board logic control for serial interface. Qorvo offers this DSA in a 3x3mm QFN package.
