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. DC Blocking capacitors are not needed on the RF paths as there

is no DC on the RF paths, however care should be taken to ensure that DC is not injected into the switch from external circuitry.

The switch has a supply input to feed the built-in logic decoding.
