RFSA3413

RFSA3413

5MHz to 6000MHz, Digital Step Attenuator

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.
