FM8545

   TheFM8545 is very low loss SP4T specifically designed for high performance antenna tuning applications. All RF path performance is enhanced with ultra-low on state resistance and off state capacitance. 

    FM8545 allows the creation of advanced tuningtopologies to maximize TRP & TIS performance in space constrained applications.

    The FM8545 SP4T tuner is provided in a compact QFN 1.1mm x 1.5mm x 0.5mm package. A functional block diagram is shown in Figure 1. 

    The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin description are provided in Table 1
