Isihlukanisi samandla, i-couple nesihlanganisi ziyizingxenye ezibalulekile zohlelo lwe-RF, ngakho-ke singathanda ukwabelana ngomehluko wako phakathi kwazo ngencazelo nomsebenzi wazo.
1.Isihlukanisi samandla: Ihlukanisa ngokulinganayo amandla esignali embobo eyodwa ukuya embobeni yokukhiphayo, ebizwa nangokuthi izihlukanisi zamandla futhi, uma isetshenziswa ngokuhlehlayo, izihlanganisi zamandla. Kungamadivaysi angenzi lutho asetshenziswa kakhulu emkhakheni wezobuchwepheshe bomsakazo. Babhangqa inani elichaziwe lamandla kazibuthe emugqeni wokudlulisela embobeni ovumela isiginali ukuthi isetshenziswe kwenye isekethe.
2.Umhlanganisi: Isihlanganisi ngokuvamile sisetshenziswa kusidlulisi. Ihlanganisa amasiginali e-RF amabili noma ngaphezulu athunyelwa emshinini owodwa we-RF othunyelwa uthi futhi igwema ukuxhumana phakathi kwamasignali embobeni ngayinye.
3.Umbhangqwana: Hlanganisa isiginali embobeni yokuhlanganisa ngokulingana.
Ngamafuphi, ukuhlukanisa isignali efanayo kumashaneli amabili noma amashaneli amaningi, vele usebenzise ngesihlukanisi samandla. Ukuhlanganisa iziteshi ezimbili noma iziteshi eziningi zibe isiteshi esisodwa, vele ube nesihlanganisi, i-POI nayo iyisihlanganisi. I-coupler ilungisa ukusabalalisa ngokuya ngamandla adingwa imbobo ukuze kuqinisekiswe ukuthi ifinyelela endaweni.
Umsebenzi wesihlukanisi samandla, isihlanganisi ne-coupler
1. Ukusebenza kwesihlukanisi samandla ukuhlukanisa ngokulinganayo isignali yefrikhwensi ephakathi yesathelayithi efakwa eziteshini eziningana zokukhipha, ngokuvamile amaphuzu wamandla amabili, amaphuzu wamandla amane, amaphuzu wamandla ayisithupha nokunye.
2. I-coupler isetshenziswa ngokuhambisana nesihlukanisi samandla ukuze kuzuzwe umgomo-ukwenza amandla okudlulisela omthombo wesignali ukuthi asatshalaliswe ngokulinganayo kumachweba wezinti zesistimu yokusabalalisa yasendlini ngangokunokwenzeka, ukuze amandla okudlulisela imbobo ye-antenna ngayinye iyafana.
3. Isihlanganisi sisetshenziswa ngokuyinhloko ukuhlanganisa amasignali esistimu eminingi ibe isistimu yokusabalalisa yasendlini. Ezinhlelweni zobunjiniyela, kuyadingeka ukuhlanganisa amafrikhwensi amabili wenethiwekhi engu-800MHz C kanye nenethiwekhi engu-900MHz G ukuze ukhiphe. Ukusetshenziswa kwesihlanganisi kungenza uhlelo lokusabalalisa lwasendlini lusebenze kukho kokubili ibhendi yefrikhwensi ye-CDMA kanye nebhendi yefrikhwensi ye-GSM ngesikhathi esisodwa.
Njengomkhiqizi weIzingxenye ze-RF passive, singaklama ngokukhethekile isihlukanisi samandla, i-couple, isihlanganisi njengesixazululo sakho, ngakho sithemba ukuthi singakusekela nganoma yisiphi isikhathi.
