Sabuwar na'urar CATV mai karɓar gani ta hanyar sadarwa mai ƙarfi mai ƙarfi guda huɗu ta kamfaninmu, mai karɓar gani ta hanyar amfani da cikakken na'urar GaAs MMIC, kuma mai ƙara haske ta hanyar amfani da na'urorin GaAs. Tare da ingantaccen ƙirar da'ira da shekaru 10 na ƙwarewar ƙira ta ƙwararru, na'urar ta sami kyakkyawan alamun aiki. Bugu da ƙari, sarrafa microprocessor da nunin sigogi na dijital suna sa gyara injiniya ya zama mai sauƙi. Ita ce babban kayan aikin da ake buƙata don gina hanyar sadarwar CATV.
