RFSA3715

5MHz to 4000MHz, Digital Step Attenuator

Package: QFN, 32-pin,

The RFMD’s RFSA3715 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 RFSA3715 features

three modes of control: serial addressable, latched parallel

and direct parallel programming. The RFSA3715 has a low

insertion loss of 1.5dB at 2GHz. Patent pending circuit

architecture providing overshoot-free transient switching

performance. External address pins allow up to eight DSAs to

be controlled on a single bus. The RFSA3715 is available in a

5mm x 5mm QFN package.

5.0mm x 5.0mm x 0.85mm
