RFSA3713TR7

RFSA3713 RFSA3713 RFSA3713 5MHz to 6000MHz, Digital Step Attenuator A2 A1 SI CLK The RFMD’s RFSA3713 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 RFSA3713 uses serial control interface. The RFSA3713 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 RFSA3713 is available in a 3mm x 3mm QFN package. 16 15 14 13 12 LE 2 11 GND GND 3 10 GND RFIN 4 9 RFOUT VDD 1 A0 LOGIC CONTROL 7-BIT DSA 8 GND 7 GND GND 6 GND 5 Functional Block Diagram Package: QFN, 16-pin, 3.0mm x 3.0mm x 0.85mm Features ■ 7-Bit, 31.75dB Range, 0.25dB Step ■ Patent Pending Circuit Architecture ■ Overshoot-free Transient Switching Performance ■ Frequency Range 5MHz to 6000MHz ■ High Linearity, IIP3 >55dBm ■ Serial Control Interface ■ Fast Switching Speed,
