Considerations for Optimal Capacitive Coupling
Abstract:
Capacitors used in coupling and DC blocking applications serve to couple RF energy from one part of a circuit to another and are implemented as series elements. Proper selection of coupling capacitors insures the maximum transfer of RF energy. All capacitors will block DC by definition; however, considerations for satisfying the requirements of a coupling application depend on various frequency-dependent parameters that must be taken into account beforehand.
