RFSA3523
5MHz to 6000MHz, Digital Step Attenuator
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.
