The FM3585 is a CMOS silicon-on-insulator (SOI), single- pole, double-throw (SPDT) switch. The high linearity and ruggedness performance and extremely low insertion loss makes the device an ideal choice for WLAN applications such as 802.11 a/b/g/n/ac/ax.

    The FM3585 SPDT switch is provided in a compact1.0mm x 1.0mm x 0.45mm 6-lead QFN package. A functional block diagram, pin configuration and package are shown in Figure 1. Signal pin assignments and functional pin descriptions are provided in Table 1.
