RFSA3623
5MHz to 6000MHz, Digital Step Attenuator
The RFMD’s RFSA3623 is a 6-bit digital step attenuator
(DSA) that features high linearity over the entire 15.75dB gain
control range with 0.25dB steps. The RFSA3623 uses serial
control interface. The RFSA3623 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 RFSA3623 is available in a 3mm x 3mm QFN
package.
