Application Schematic
Application Diagram and Guidelines
The decoupling capacitors are optional and, if necessary, may be used for noise reduction. Decoupling capacitors on the con-
trol pins protect the control circuitry from possible RF leakage. An ESD filter is needed to protect the switch from antenna ESD
events. The filter is formed by LESD inductor and CESD capacitor. The switch has a supply input to feed the built-in logic decod-
ing.
