Understanding the Importance of Reflected Power in Combiner Systems

Understanding the Importance of Reflected Power in Combiner Systems In a combiner system, power that's reflected at the antenna port doesn't make it to the antenna, instead, it is reflected back and dissipated as heat in the isolator output load

Which Antenna Duplexer is right for you?

Which Antenna Duplexer is right for you? There are several factors involved in choosing the right duplexer for your application.  Most consider only TX power and frequency offset when deciding whether a duplexer fits their application.  While ...
