Theoryofoperation
Theunithastwoexternalantennaportsontherearoftheunit.Oneisforthetransmitter(TX
Ant)andtheotherisforthereceiver(RXAnt).Theseportswouldbenormallyattachedtothe
customersuppliedduplexer. 

TherepeaterisconfiguredwithoneRFPoweramplifierassemblywhichrequiresapproximately
100mwofdrivefromthemodulemarked“Transmitter”whichcontainsthecontrollogicand
theTX‐RXboard.The100mwofRFisthenroutedtothePAAmplifierassemblyandamplifies
thatsignalto45‐110watts,whichisthenroutedtotheTXAntennaport.
TherepeaterisconfiguredwithasecondcontrollogicandTX‐RXboardinwhichthereceiver
onlyisusedforfullduplexoperation.ThereceiverfrontendhastheadditionofaFrontend
