decoupled power splitter 400 470 mhz the decoupled power splitter can be used for power distribution for example from one common antenna to several receivers of arbitrarily low frequency spacing for power distribution for example from one transmitter to several outputs for decoupled combining of several transmitters with arbitrarily low frequency spacing loss 4.7 db resp 6 db for decoupled combining of several transmitting/receiving units whose integrated duplexers are within the same frequency range function the decoupled power splitter has 3 or 4 inputs one output as well as 3 or 4 absorber ports the inputs are only decoupled when the absorber ports are terminated with 50-Ω loads of suitable power 725871 the absorbers of the 3:1-power splitter have to be dimensioned so that at least 2/3 of the power fed into the inputs can be absorbed example if a power of 50 w is fed into every input the absorbers have to absorb 33 w each the absorbers of the 4:1 power splitter have to be
