RFSA3613 RFSA3613 5MHz to 6000MHz, Digital Step Attenuator Package: QFN, 16-pin, The RFMDs RFSA3613 is a 6-bit digital step attenuator 3.0mm x 3.0mm x 0.85mm (DSA) that features high linearity over the entire 31.5dB gain Features control range with 0.5dB steps. The RFSA3613 uses serial 6-Bit, 31.5dB Range, 0.5dB Step control interface. The RFSA3613 has a low insertion loss of Patent Pending Circuit Architecture 1.4dB at 2GHz. Patent pending circuit architecture provides Overshoot-free Transient overshoot-free transient switching performance. External Switching Performance address pins allow up to eight DSAs to be controlled on a Frequency Range 5MHz to single bus. The RFSA3613 is available in a 3mm x 3mm QFN 6000MHz package.
