RFSA3714
50MHz to 6000MHz, Digital Step Attenuator
The RFMD’s RFSA3714 is a 7-bit digital step attenuator
(DSA) that features high linearity over the entire 31.75dB gain
control range with 0.25dB steps. The RFSA3714 features
three modes of control: serial, latched parallel, and direct
parallel programming. The RFSA3714 has a low insertion loss
of 1.5dB at 2GHz. Patent pending circuit architecture provides
Overshoot-free transient switching performance. The
RFSA3714 is available in a 4mm x 4mm QFN package.
