Ubudlelwano phakathi kwe-RF front-end ne-RF chip
I-RF front-end nama-RF chips ahlobene eduze, futhi kokubili akuhlukaniseki. I-RF front-end iyingxenye ebalulekile yolwazi nokucubungula isignali. Kubhekiselwa ohlelweni lwesekethe ukusuka ku-antenna kuya ku-amplifier yokugcina. I-chip yefrikhwensi yomsakazo iyisekhethi edidiyelwe yamasekhethi efrikhwensi yomsakazo, amasekhethi e-microwave kanye nobuchwepheshe be-antenna, esebenzisa ngokuyinhloko umsebenzi wokucubungula amasignali amaza omsakazo. Ubudlelwano phakathi kwe-RF front-end kanye ne-RF chip buchazwe kabanzi ngezansi.
Okokuqala, i-RF front-end isho uhlelo lwesekethe oluqala ukusuka ku-antenna ukuya esigabeni sokugcina se-amplifier. I-RF front-end ihlanganisa izimpondo, ama-jumpers, izilawuli, ama-biasers, ama-amplifiers nezihlungi, njll., futhi iyimojuli eyinhloko okufanele amasiginali e-RF adlule kuyo. I-RF front-end inemisebenzi eminingi ebalulekile, njengokukhulisa amasiginali asezingeni eliphansi ukusuka othini ngokusebenzisa izikhulisi nokukhipha amasiginali womsindo neziphazamiso ngezihlungi. Ezokuxhumana ngefrikhwensi yomsakazo, isiphetho sefrikhwensi yomsakazo idlala indima ebalulekile. Noma ngabe omakhalekhukhwini, omabonakude, noma ezokuxhumana ngomsakazo, indawo engaphambili yefrikhwensi yomsakazo iyingxenye ebalulekile yale mishini ukuze kuzuzwe imisebenzi yokuxhumana okungenantambo.
Okwesibili, i-chip yefrikhwensi yomsakazo iyisekhethi edidiyelwe yesekethe yefrikhwensi yomsakazo, isekethe ye-microwave kanye nobuchwepheshe be-antenna, esebenzisa ngokuyinhloko umsebenzi wokucubungula amasignali efrikhwensi yomsakazo. Umsebenzi obalulekile we-chip ye-RF ukukhulisa nokwehlisa isiginali ye-RF ebuthaka kusukela ekugcineni kwe-RF. Ukuqaliswa nokuklanywa kwama-chip chips akunakuhlukaniswa ne-RF front-end. Uma kuqhathaniswa namasekhethi okuxhumana ajwayelekile, ama-chips amafrikhwensi omsakazo anezidingo eziphakeme zesivinini sokucubungula isignali nokunemba. Ngakho-ke, ama-chips amafrikhwensi omsakazo ngokuvamile asebenzisa izici zokuhlanganiswa okuphezulu, ukwethembeka okuphezulu, nokusetshenziswa kwamandla okuphansi. Emikhakheni efana nezokuxhumana ngomakhalekhukhwini, omabonakude, amakhaya ahlakaniphile nokuzulazula, ama-chips erediyo adlala indima ebalulekile.
Ngaphezu kwalokho, ukubambisana phakathi kwe-RF front-end kanye ne-RF chip kubalulekile. Amasignali amafrikhwensi omsakazo abalulekile ekwakhiweni kwemikhiqizo ye-elekthronikhi, kodwa amasignali amafrikhwensi omsakazo anezici eziningi, njengefrikhwensi ephezulu, isignali ebuthakathaka, nesilinganiso esiphansi sesignali-kuya-nomsindo. Ngakho-ke, indlela yokuqalisa nokusebenzisa kahle ukwakheka kwesekethe ye-RF kanye nokwenza kahle kwesistimu ngaphansi kokucubungula ngesivinini esikhulu kanye nezidingo zokusetshenziswa kwamandla aphansi kuyinselele enkulu. Ukubambisana phakathi kwe-RF front-end ne-RF chip kudinga ukwenziwa kuzo zonke izici zomklamo wesekethe ye-RF. Lokhu kudinga onjiniyela abangochwepheshe ukuthi baqonde amaphuzu abalulekile njengokulahleka kwe-RF, ukuphazamiseka, kanye nokuvimbela ukuphazamiseka ukuze kwenziwe umklamo we-RF ophumelelayo.
Ukufingqa, i-RF front-end ne-RF chip yizingxenye ezimbili ezibalulekile zokufinyelela ukuxhumana kwe-RF. I-RF front-end isebenzisa imisebenzi efana nokukhulisa, ukuhlunga, nokucutshungulwa kwamasignali e-RF, kuyilapho i-RF chip isebenzisa imisebenzi yokucubungula isignali efana nokuguquguquka, ukwehlisa, nokukhulisa amasignali e-RF. Ukubambisana okuhle kakhulu kuphela phakathi kwe-RF front-end ne-chip ye-RF okungafinyelela ukuxhumana kwe-RF okusebenzayo nokunamandla aphansi. Ngokuthuthuka kobuchwepheshe bolwazi kanye nokwanda kwezinkambu zokufaka izicelo, isidingo nezimfuneko zama-front ends nama-chip chips e-RF ziya ngokuya ziba phezulu. Ngokuzayo, bazoqhubeka nokudlala indima ebalulekile kwezokuxhumana okungenantambo, i-inthanethi Yezinto, amakhaya ahlakaniphile kanye neminye imikhakha. .
