Isihlanganisi se-TETRA Esihlukanisiwe Esiphezulu se-380-470MHz
I-TETRA combiner iyidivayisi ye-RF esetshenziswa ezinhlelweni ze-TETRA (Terrestrial Trunked Radio) ukuhlanganisa iziteshi eziningi zokudlulisa noma zokwamukela ku-antenna eyodwa noma inani elincishisiwe lama-antenna port. Umsebenzi ⭐Ihlanganisa ama-transmitter amaningi esiteshi se-TETRA abe yisistimu eyodwa ye-antenna...Funda kabanzi -
Abahlaziyi be-Intermodulation abangasebenzi
Njengoba izidingo zezinhlelo zokuxhumana zeselula zikhula, i-Passive Intermodulation (PIM) isibe yinkinga ebalulekile. Izimpawu zamandla aphezulu eziteshini zokudlulisa ezabiwe zingabangela ukuthi izingxenye eziqondile ngokwesiko ezifana nama-duplexer, izihlungi, ama-antenna, kanye nezixhumi zibonise izici ezingezona eziqondile...Funda kabanzi -
Indima ye-RF front-end ezinhlelweni zokuxhumana
Ezinhlelweni zokuxhumana zesimanje, i-Radio Frequency (RF) front-end idlala indima ebalulekile ekwenzeni ukuxhumana okungenantambo kube ngcono. Njengoba ibekwe phakathi kwe-antenna kanye ne-digital baseband, i-RF front-end inesibopho sokucubungula amasignali angenayo naphumayo, okwenza kube...Funda kabanzi -
Izixazululo ezithuthukisiwe zezinhlelo zokuxhumana eziphuthumayo zokuphepha komphakathi
Emkhakheni wokuphepha komphakathi, izinhlelo zokuxhumana eziphuthumayo zibalulekile ekugcineni ukuxhumana ngesikhathi sezinhlekelele. Lezi zinhlelo zihlanganisa ubuchwepheshe obuhlukahlukene njengezinkundla eziphuthumayo, izinhlelo zokuxhumana ngesathelayithi, izinhlelo zamaza amafushane kanye namaza amafushane, kanye nokuqapha ukuzwela okukude ...Funda kabanzi
