Abatshatisi abatshatileyo yimilinganiselo esemgangathweni ye-microwave / i-millimeter yamaza kumlinganiso we-microwave kunye nezinye iinkqubo zemicrowae. Banokusetyenziselwa ukubekwa kwemveliso, ukwahlukana, nokuxuba, njengokubekwa kweliso kulwakhiwo, ukubekwa kwamandla ombane, i-Stonel Sport, i-Storction Stores, kwaye liyinxalenye yokubonisa i-frequency ye-frequency ye-frequency. Ngokwesiqhelo, zininzi iindidi, ezinjengeWeeGuide, umgca we-coaxial, umhluzi, kunye ne-Microstrip.
Umzobo 1 ngumzobo occhematic wesakhiwo. Ibandakanya iinxalenye ezimbini, eyona ndawo iphambili kunye nomgca oncedisayo, odityaniswa kunye ngeendlela ezahlukeneyo zemingxunya emincinci, izilayidi, kunye nezithuba. Ke ngoko, inxenye yegalelo lamandla ukusuka kwi "1" kwisiphelo esiphambili siya kudityaniswa kumgca wesibini. Ngenxa yokuphazamiseka okanye ukonakaliswa kwamaza, amandla aya kudluliselwa kuphela kumgca wesibini-icala elinye (elibizwa ngokuba "thumela"), kwaye enye iphantse yanda (ebizwa ngokuba "jika")
Umzobo 2 sisibini esinqongophayo, elinye lamazibuko kwi-sperts liqhagamshelwe kumthwalo otshintshiweyo otshintshiweyo.
Ukusetyenziswa kwesibini esitshatileyo
1, Kwinkqubo ye-synthesis ye-synthesis
I-3DB i-tender (yaziwa ngokuba yi-3DB Bridge) idla ngokusetyenziswa kwi-Multied Rier Frecial Synthesis synthesi, njengoko kubonisiwe kumzobo ongezantsi. Olu hlobo lwesekethe luxhaphakile kwiinkqubo ze-Indoor. Emva kwemiqondiso f1 kunye ne-F2 ukusuka kwi-Amplifiers ezimbini ze-Amplifies ehamba-hlulo, ukukhutshwa kwesitayile ngasinye kune-Frequency Ene-FORTATE yecandelo le-F1 kunye ne-3DB linciphisa i-AMLB icandelo ngalinye. Ukuba enye yeethebhu zemveliso iqhagamshelwe kumthwalo wokufunxa, ezinye iziphumo zinokusetyenziswa njengokwenziwa kwamandla kwiNkqubo yokulinganisa i-promomouse. Ukuba ufuna ukuphucula ukodwa ngakumbi, unokongeza amanye amacandelo anjengeefilitha kunye nesolators. Ukuhlukaniswa kwebhlorho ye-3DB ye-3DB kunokuba ngaphezulu kwe-33DB.
Isibini esitshatileyo sisetyenziswa kwiNkqubo yokuChuka kweMibala enye.
Indawo ye-gully ye-gully njengesinye isicelo sokudityaniswa kwamandla kubonisiwe kumzobo (a) ngezantsi. Kule sekethe, ingqumbo yesibini esibonisa ukuba isibini sisetyenzisiwe ngobulumko. Ukuthatha ukuba amanqanaba okudibana kwabatshatileyo bobabini babini be-10db kunye ne-rofiture zombini i-25db, ukuhlukaniswa phakathi kwe-F1 kunye ne-F2 iphele i-45db. Ukuba igalelo le-F1 kunye ne-F2 i-0dbm, iziphumo ezidityanisiweyo zenziwe zombini -10dBM. Xa kuthelekiswa ne-WILKINSON STRICRN kwi-10 Xa kuthelekiswa nemeko yesampulu yesampulu, sandisa isigutyana Ngeli xesha, ukuhlukaniswa phakathi kwe-F1 kunye ne-F2 kwi-10 kwi " Isiphumo sokugqibela sokuthelekisa kukuba indlela ye-Spernthel ye-Synthesis ye-Synthesis yi-18db ephezulu kune-wilkinson isibini. Esi sikimu silungele ukulinganiswa kwemilinganiselo ye-Amplifies ezilishumi.
Isibini esitshatileyo sisetyenziswa kwiNkqubo yokuCwangciswa kwamandla 2
I-2, isetyenziselwe ukulinganisa i-anti-phars
Kwinkqubo yovavanyo lwe-RF kunye nenkqubo yokulinganisa, isiphaluka esiboniswe kumzobo ongezantsi sihlala sibonwa. Masithi isithuba (isixhobo okanye izixhobo eziphantsi kovavanyo) ngumamkeli. Kwimeko enjalo, isiginali yokuphazamiseka kwejelo esikufuphi nayo inokufakwa kumhlatho ngokusebenzisa isibini esitshatileyo. Emva koko i-titer ehlanganisiweyo ixhunyiwe kubo ngesibini esibonisa ukuba sinokuvavanya umamkeli wamamkeli-i-Internations yokusebenza. Ukuba i-Datin yifowuni yeselula, ukuntywila kwefowuni kungavulwa yi-tester ebanzi edityanisiweyo kwi-coupling yesibini esitshatileyo. Emva koko uhlalutyo lwe-shoctrium lungasetyenziselwa ukulinganisa iziphumo ezikhoyo zefowuni. Ewe kunjalo, ezinye iziphaluka ezicocekileyo kufuneka zongezwe phambi kohlalutyo lwe-spectrium. Ekubeni lo mzekelo uxoxa kuphela kukusetyenziswa kwabatshati abatshatileyo, iSekethi yeFilter ishiyiwe.
Isibini esitshatileyo sisetyenziselwa ukulinganisa okuchasene ne-Privest okanye ukuphakama kwefowuni yeselula.
Kwezi sekethe yovavanyo, imvakalo-mali yesibini ibaluleke kakhulu. I-spectrum valtumer exhunywe kwi-Treat ifuna kuphela ukuba ifune umqondiso ukusuka esikolweni kwaye ayifuni ukufumana iphasiwedi kwi-password yokuphela.
I-3, yesampulu yomqondiso kunye nokubeka iliso
Ukuhambisa umlinganiso we-Intanethi kunye nokubekwa kweliso kunokuba yenye yezona zicelo zisetyenzisiweyo zisetyenzisiweyo zabatshati abatshatileyo. Eli nani lilandelayo sisicelo esiqhelekileyo sabatshaba abakhokelayo kumlinganiso wesiphelo seselula. Masithi amandla okukhupha i-Transmitter yi-43dbm (20w), ukudibanisa isibini esibonisa isibini. Umthamo yi-30db, ilahleko yokufakelwa (ilahleko yomgca kunye ne-Coupling Coulting) yi-0.15db. Isiphelo sokudibana sine-13dBM (20MW) isiginali ethunyelweyo kwisiseko se-tester, isiseko ngqo sesibini esitshatileyo yi-42.85DBM (19.3), kwaye ukuvuza ngamandla kwicala elikwanti kungeniswa ngumthwalo.
Isibini esitshatileyo sisetyenziselwa umlinganiso wesiKhululo esisiseko.
Phantse bonke abantu abadlulayo basebenzisa le ndlela yesampulu ye-intanethi kunye nokubek'esweni, kwaye mhlawumbi le ndlela kuphela inokuqinisekisa uvavanyo lwentsebenzo yodluliselo phantsi kweemeko eziqhelekileyo zomsebenzi. Kodwa kufuneka kuqatshelwe ukuba ngokufanayo luvavanyo losasazo, kwaye ii-testers ezahlukeneyo zineenkxalabo ezahlukeneyo. Ukuthatha izikhululo zeWCDMA njengomzekelo, abaqhubi kufuneka banikele ingqalelo kwizikhombisi kwibhendi yalo yokusebenza (2170mhz), i-2110 ~ 2170MHz) IZiko loLawulo ngalo naliphi na ixesha.
Ukuba nguMlawuli we-Direquency Readcture-isitishi sokubeka iliso kwirediyo sokuvavanya izikhululo seSitimela esithambileyo, ugxininiso lwayo luhlukile ngokupheleleyo. Ngokweemfuno zolawulo lwerediyo, uluhlu lwe-frequency longezwa ukuya kwi-9khz ~ 12.75ghz, isikhululo esisiseko esivavanyiweyo sibanzi kakhulu. Ingakanani imitha yemitha ekhuselweyo iya kuveliswa kwibhendi ehamba rhoqo kwaye iphazamisane nokusebenza rhoqo kwezinye izikhululo zesiseko? Inkxalabo yezikhululo zokubeka irediyo zikamathotholo. Ngeli xesha, isibini esibonisa ukuba isibini esibonisa i-bandwidth esifanayo siyadingeka kwisampulu yomqondiso, kodwa isibini esibonisa isibini esinokugubungela i-9KHZ ~ 12.75gzz ayibonakali ngathi ayikho. Siyazi ukuba ubude bengalo yokudibanisa isibini esibonisa ukuba sihambelana nexesha layo rhoqo. I-bandwidth yesibini esibanzi se-Ultra esine-Ultra esine-onder sinokufikelela kwi-5-6 i-octch band, ezinje nge-0.5-18ghz, kodwa i-frequency yendawo engaphantsi kwe-500mhz ayinakugutyungelwa.
4, I-intanethi ye-Intanethi
Kumgangatho weTekhnoloji yoThengiso lweTekhnoloji, isibini esibonisa isibini sisixhobo esibaluleke kakhulu. Eli nani lilandelayo libonisa umzobo occhematic wedrafti of special-yenkqubo yokulinganisa amandla amakhulu. Amandla angaphambili avela kwi-Amplifier ephantsi kovavanyo asampulu yesaperal i-coupling yokuphela (i-terminal 3) yesibini esitshatileyo kwaye sathunyelwa kwimitha yamandla. Amandla abonakalisiweyo asampululwa kwi-reupiling termil yesiphelo (isiphelo se-4) kwaye uthunyelwe kwimitha yamandla.
Isibini esitshatileyo sisetyenziselwa ukulinganisa amandla aphezulu.
Nceda uqaphele: Ukongeza ekufumaneni amandla abonakalisiweyo kumthwalo, i-reuping yesiphelo sendlela (i-termil 4) ifumana amandla okuvuza ukusuka kwisibini sangaphambili (isiphelo se-1), ebangelwa sisibini esitshatileyo. Amandla abonakalisayo yile nto ithembayo yokulinganisa, kwaye amandla okuvuza ngowona mthombo ophambili weempazamo kwimilinganiselo yamandla ebonakalisiweyo. Amandla abonakalisiweyo kunye nokuvuza amandla aphunyezwe kwi-reuping yokuphela kwe-reuping (i-4 uphela) emva koko athunyelwe kwimitha yamandla. Kuba iindlela zokudluliselwa kwemiqondiso emibini zahlukile, yindawo esongelweyo ye-vector. Ukuba igalelo lamandla elivuza kwimitha yamandla inokuthelekiswa namandla abonakalisiweyo, iya kuvelisa impazamo enkulu yomlinganiselo.
Ewe, amandla abonakalisiweyo kumthwalo (ukuphela kwe-2) uya kuvuza ukuya kwi-coupling yokuphela kokudibana (ukuphela 1, akaboniswanga kumzobo ongentla). Nangona kunjalo, ubukhulu bayo bubuncinci xa kuthelekiswa namandla ngaphambili, amisa amandla. Impazamo ebangelweyo inokungahoywa.
