Isihluli samandla, isibini kunye nesihlanganisi zizinto ezibalulekileyo zenkqubo yeRF, ngoko ke singathanda ukwabelana nomahluko phakathi kwazo kwingcaciso kunye nomsebenzi wazo.
1.Isahluli samandla: Yahlula ngokulinganayo amandla omqondiso wezibuko elinye ukuya kwizibuko lemveliso, elikwabizwa ngokuba zizahluli zamandla kwaye, xa isetyenziswa umva, izihlanganisi zamandla. Zizixhobo zokwenziwa ezisetyenziswa kakhulu kwicandelo lobuchwepheshe berediyo. Badibanisa isixa esichaziweyo samandla ombane kumgca wothumelo kwizibuko elivumela ukuba umqondiso usetyenziswe kwenye isekethe.
2.Umdibanisi: Umhlanganisi usetyenziswa ngokubanzi kwi-transmitter. Idibanisa iisignali zeRF ezimbini okanye ngaphezulu ezithunyelwa zisuka kwiitransmitha ezahlukeneyo kwisixhobo esinye seRF esithunyelwe yi-eriyali kwaye inqanda ukusebenzisana phakathi kwemiqondiso kwizibuko ngalinye.
3.Umlingane: Dibanisa umqondiso kwizibuko lokudibanisa ngokomlinganiselo.
Ngamafutshane, ukwahlula isignali efanayo kwiitshaneli ezimbini okanye iziteshi ezininzi, sebenzisa nje nge-splitter yamandla. Ukudibanisa amajelo amabini okanye amajelo amaninzi kwitshaneli enye, yiba nomdibanisi nje, i-POI ikwangumhlanganisi nayo. I-coupler ilungelelanisa ukuhanjiswa ngokwamandla afunwa lizibuko ukuqinisekisa ukuba ifikelela kwindawo.
Umsebenzi wokwahlula amandla, umdibanisi kunye ne-coupler
1. Ukusebenza kwesahluli samandla kukwahlula ngokulinganayo igalelo lesathelayithi ephakathi kwesiginali yefrikhwensi kwiitshaneli ezininzi zemveliso, ngokuqhelekileyo iindawo zamandla amabini, iindawo zamandla ezine, iindawo zombane ezintandathu njalo njalo.
2. I-coupler isetyenziswe ngokubambisana ne-splitter yamandla ukufezekisa injongo-ukwenza amandla okudluliselwa komthombo wesignali ukuba asasazwe ngokulinganayo kwizibuko ze-eriyali zenkqubo yokusabalalisa yangaphakathi kangangoko kunokwenzeka, ukwenzela ukuba amandla okuhambisa izibuko leeriyali nganye ngokwesiseko iyafana.
3. Umdibanisi usetyenziselwa ikakhulu ukudibanisa iimpawu ze-multi-system kwi-system distribution yangaphakathi. Kwizicelo zobunjineli, kuyimfuneko ukudibanisa iifrikhwensi ezimbini ze-800MHz C inethiwekhi kunye ne-900MHz G yenethiwekhi yemveliso. Ukusetyenziswa komdibanisi kunokwenza inkqubo yokuhambisa yangaphakathi isebenze kuzo zombini ibhendi yeCDMA frequency kunye neGSM frequency band ngaxeshanye.
Njengomvelisi weAmalungu e-RF asebenzayo, singayila ngokukodwa isahluli samandla, isibini, isihlanganisi njengesisombululo sakho, ke sinethemba lokuba sinokukuxhasa nangaliphi na ixesha.
