RFSA3523

5MHz to 6000MHz, Digital Step Attenuator

Package: QFN, 16-Pin,

The RFMD’s RFSA3523 is a 5-bit digital step attenuator

(DSA) that features high linearity over the entire 15.5dB gain

control range with 0.5dB steps. The RFSA3523 uses serial

control interface. The RFSA3523 has a low insertion loss of

1.4dB at 2GHz. Patent pending circuit architecture provides

overshoot-free transient switching performance. External

address pins allow up to eight DSAs to be controlled on a

single bus. The RFSA3523 is available in a 3mm x 3mm QFN

package.

3.0mm x 3.0mm x 0.85mm
