Itekhnoloji yeMicrowave yaseSichuan Keenlion——isahluli samandla
Itekhnoloji yeSichuan Keenlion Microwave Technology eyasekwa ngo-2004, iSichuan Keenlion Mircrowave techenology CO., Ltd. ngumenzi ophambili wezixhobo zePassive Mircrowave eSichuan Chengdu, eTshayina.
Sinikezela ngezixhobo ze-mirrowave ezisebenza kakuhle kunye neenkonzo ezinxulumene nazo kwii-microwave ekhaya nakwamanye amazwe. Ezi mveliso zixabisa kancinci, kuquka izixhobo ezahlukeneyo zokwahlula amandla, izixhobo zokudibanisa ezikhokelayo, izihluzi, izixhobo zokudibanisa, izixhobo zokudibanisa, izixhobo zokudibanisa, izixhobo ezizenzekelayo ezingasebenziyo, izixhobo zokwahlulahlula kunye nezixhobo zokujikeleza. Iimveliso zethu zenzelwe ngokukodwa iimeko ezahlukeneyo zobushushu kunye namaqondo obushushu agqithisileyo. Iinkcukacha zinokwenziwa ngokweemfuno zabathengi kwaye ziyasebenza kuzo zonke iibhendi zefrikhwensi ezisemgangathweni nezithandwayo ezineebhendi ezahlukeneyo ukusuka kwi-DC ukuya kwi-50GHz.
isahluli samandla

Isihluzi samandlasisixhobo esahlula amandla esignali yokungenisa ibe ziitshaneli ezimbini okanye ngaphezulu kwaye sikhuphe amandla alinganayo okanye angalinganiyo. Ngenxa yoko, sinokudibanisa amandla esignali amaninzi abe yimveliso enye. Ngeli xesha, sinokubizwa ngokuba yi-combiner.

Kuya kuqinisekiswa ukuba kukho inqanaba elithile lokuzihlukanisa phakathi kwezibuko zokukhupha zesixhobo sokwahlula amandla. Umatshini wokusasaza amandla ukwabizwa ngokuba yi-over-current distributor, eyahlulwe yaba yi-active kunye ne-passive. Ingasasaza ngokulinganayo isignali enye kwiimveliso ezininzi. Ngokubanzi, itshaneli nganye encinci ine-dB attenuation ezininzi. Ukuncitshiswa kwabasasazi abahlukeneyo nako kwahlukile ngenxa yeefrikhwensi ezahlukeneyo zesignali. Ukuze kulungiswe ukuncitshiswa, kwenziwa isixhobo sokwahlula amandla esingasebenziyo emva kokongeza i-amplifier.

Intshayelelo yomsebenzi

Umsebenzi womsasazi wamandla kukwahlula ngokulinganayo isathelayithi ukuba ingenisa isignali ukusuka kwitshaneli enye ukuya kwiitshaneli ezininzi zokukhupha, ngokuqhelekileyo kubandakanya ukwahlulwahlulwa kwamandla amabini, ukwahlulwa kwamandla amane, ukwahlulwa kwamandla amathandathu njalo njalo. Ukusetyenziswa kunye nokusebenza kwezi zixhobo zithathu zingasentla kwahlukile ngokupheleleyo, kodwa kulula ukubhidanisa amagama ekusetyenzisweni kwemihla ngemihla, nto leyo eyenza abantu badideke xa besetyenziswa. Iisathelayithi ezininzi kwinkqubo yokufumana iTV yesathelayithi zabelana nge-antenna enye, ii-antenna ezininzi zabelana ngesathelayithi enye, kunye neesathelayithi ezingaphezulu kwezibini kunye nee-antenna ezingaphezu kwezibini zabelana. Ukongeza kwiintambo, unxibelelwano phakathi kwazo luqatshelwa ngokudityaniswa.

ucwangciso lweeswitshi. Umsasazi wamandla usetyenziselwa ukuqhagamshela abamkeli besathelayithi abaninzi. Ukuba iseti yee-antenna kufuneka iqhagamshelwe kubamkeli besathelayithi abaninzi, kufuneka kusetyenziswe umsasazi wamandla. Khetha umsasazi wamandla ngokwenani labamkeli abadibeneyo. Ukuba abamkeli ababini baqhagamshelwe, kusetyenziswa umsasazi wamandla amabini. Qhagamshelana nabamkeli abane kwaye usebenzise abasasazi bamandla abane.

Izalathisi zobugcisa

Ii-index zobugcisa zomsasazi wamandla ziquka uluhlu lweefrikhwensi, amandla okuthwala, ilahleko yokusasazwa ukusuka kwisekethe ephambili ukuya kwisebe, ilahleko yokufakwa phakathi kokufakwa kunye nokuphuma, ukwahlulwa phakathi kwee-ports zesebe, umlinganiselo wamaza okuma kwe-voltage kwi-port nganye, njl.njl.

1. Uluhlu lweefrikhwensi. Le yindlela yokusebenza kwiisekethe ezahlukeneyo ze-RF / microwave. Uyilo lolwakhiwo lombane lunxulumene kakhulu nefrikhwensi yokusebenza. Ifrikhwensi yokusebenza yombane kufuneka ichazwe ngaphambi kokuba kwenziwe olu yilo lulandelayo.

2. Ukumelana namandla. Kwi-high-power distributor/synthesizer, amandla aphezulu anokuthwala izinto zesekethe yi-core index, emisela ukuba loluphi uhlobo lomgca wokudlulisa onokusetyenziswa ukufezekisa umsebenzi woyilo. Ngokubanzi, ulandelelwano lwamandla oluthwalwa ngumgca wokudlulisa ukusuka kumncinci ukuya kumkhulu ngumgca we-microstrip, umgca we-strip, umgca we-coaxial, umgca we-air strip kunye nomgca we-air coaxial. Ngowuphi umgca omele ukhethwe ngokwemisebenzi yoyilo.

3. Yabela ilahleko. Ilahleko yokusasazwa ukusuka kwisekethe ephambili ukuya kwisekethe yesebe ngokuyintloko inxulumene nomlinganiselo wokusasazwa kwamandla womsasazi wamandla. Umzekelo, ilahleko yokusasazwa kwezahluli zamandla ezimbini ezilinganayo yi-3dB kwaye eyahluli zamandla ezine ezilinganayo yi-6dB.

4. Ukulahleka kokufakwa. Ukulahleka kokufakwa phakathi kokufakwa kunye nokuphuma kubangelwa yi-medium engaphelelanga okanye umqhubi womgca wothumelo (njengomgca we-microstrip), kuthathelwa ingqalelo ukulahleka okubangelwa yi-standing wave ratio kwi-input.

5. Ukuzahlula. Ukuzahlula phakathi kwee-ports zamasebe lolunye uphawu olubalulekileyo lomsasazi wamandla. Ukuba amandla okufaka avela kwi-port nganye yamasebe anokuphuma kuphela kwi-port ephambili kwaye akufanele aphume kwamanye amasebe, kufuneka azahlukanise ngokwaneleyo phakathi kwamasebe.

6. Umlinganiselo wamaza amileyo. Okukhona i-VSWR incinci kwizibuko ngalinye, kokukhona ingcono.

Iisahluli samandlainokwahlulwahlulwa ibe ziindidi ezimbini ngokwesakhiwo:

（1） Iimpawu eziphambili zesihluli samandla esingasebenziyo zezi: ukusebenza okuzinzileyo, ulwakhiwo olulula kwaye ngokusisiseko akukho ngxolo; Ingxaki yayo ephambili kukuba ilahleko yokufikelela inkulu kakhulu.

（2） Isihluzi-mandla esisebenzayo senziwe nge-amplifier. Iimpawu zaso eziphambili zezi: inzuzo kunye nokwahlulwa okuphezulu. Iingxaki zaso eziphambili yingxolo, isakhiwo esintsonkothileyo kunye nokuzinza okuphantsi kokusebenza. Isango lokukhupha le-power divider linamachaphaza amabini, amachaphaza amathathu, amachaphaza amane, amachaphaza amathandathu, amachaphaza asibhozo kunye namachaphaza alishumi elinesibini.

Igama elipheleleyo lokwahlula amandla yi-power divider. Sisixhobo esahlula amandla esignali yokungenisa ibe ziitshaneli ezimbini okanye ngaphezulu kwaye sikhuphe amandla alinganayo okanye angalinganiyo. Ngenxa yoko, sinokudibanisa amandla esignali amaninzi kwimveliso enye. Ngeli xesha, sinokubizwa ngokuba yi-combiner. Umlinganiselo othile wokuzahlula kufuneka uqinisekiswe phakathi kwee-output ports ze-power divider. Ngokwemveliso, i-power divider idla ngokwahlulwa ibe yinye ibe zimbini (i-input enye kunye ne-outputs ezimbini), enye ibe zithathu (i-input enye kunye ne-outputs ezintathu), njl. Iiparameter eziphambili zobugcisa ze-power divider ziquka ukulahleka kwamandla (kubandakanya ukulahleka kokufakwa, ukulahleka kokusasazwa kunye nokulahleka kokubonakalisa), umlinganiselo wamaza okuma kwe-voltage ye-port nganye, ukwahlukana phakathi kwee-power distribution ports, i-amplitude balance, i-phase balance, amandla ombane kunye nobubanzi bebhendi ye-frequency.

Singakwazi nokwenza ngokwezifiso iinxalenye ze-rf passive ngokweemfuno zakho. Ungangena kwiphepha lokwenza ngokwezifiso ukuze unikeze iinkcukacha ozifunayo.
