Ubuchwepheshe be-Microwave be-Sichuan Keenlion——isihlukanisi samandla
Ubuchwepheshe be-Microwave beSichuan Keenlion Obusungulwe ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye ze-Passive Mircrowave eSichuan Chengdu, eShayina.
Sinikeza izingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezinhlelo zokusebenza ze-microwave ekhaya nakwamanye amazwe. Imikhiqizo ishibhile, kufaka phakathi i-power divider ehlukahlukene, ama-directional couplers, ama-filters, ama-combiners, ama-duplexers, izingxenye ezingasebenzi ezenziwe ngokwezifiso, ama-isolators nama-circulator. Imikhiqizo yethu yenzelwe ngokukhethekile izindawo ezahlukene kanye namazinga okushisa aphezulu. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi isebenza kuwo wonke ama-frequency band ajwayelekile nathandwayo anama-bandwidth ahlukahlukene kusukela ku-DC kuya ku-50GHz.
isihlukanisi samandla

Isihlukanisi samandlaiyithuluzi elihlukanisa amandla esignali eyodwa yokufaka ibe iziteshi ezimbili noma ngaphezulu bese likhipha amandla alinganayo noma angalingani. Futhi, lingahlanganisa amandla esignali amaningi abe umphumela owodwa. Ngalesi sikhathi, lingabizwa nangokuthi i-combiner.

Izinga elithile lokuhlukaniswa kufanele liqinisekiswe phakathi kwama-port okukhiphayo kwesihlukanisi samandla. Umsabalalisi wamandla ubizwa nangokuthi umsabalalisi we-over-current, ohlukaniswe phakathi kwe-active kanye ne-passive. Ungasabalalisa ngokulinganayo isignali eyodwa ekuphumeni okuningana. Ngokuvamile, isiteshi ngasinye esincane sinokuncishiswa kwe-dB okuningana. Ukuncishiswa kwabasabalalisi abahlukene nakho kuhlukile ngenxa yamaza omsindo ahlukene esignali. Ukuze kulungiswe ukuncishiswa, kwenziwa isihlukanisi samandla esingasebenzi ngemva kokufaka i-amplifier.

Isingeniso somsebenzi

Umsebenzi womsabalalisi wamandla ukuhlukanisa ngokulinganayo isathelayithi uma ingena ngesignali kusuka esiteshini esisodwa iye eziteshini eziningana zokukhipha, ngokuvamile kufaka phakathi ukwahlukaniswa kwamandla amabili, ukwahlukaniswa kwamandla amane, ukwahlukaniswa kwamandla ayisithupha njalo njalo. Ukusetshenziswa nokusebenza kwamadivayisi amathathu angenhla kuhluke ngokuphelele, kodwa kuvame ukuba lula ukudideka amagama ekusetshenzisweni kwansuku zonke, okwenza abantu badideke lapho besetshenziswa. Abamukeli besathelayithi abaningi ohlelweni lokwamukela i-TV yesathelayithi babelana nge-antenna eyodwa, ama-antenna amaningana abelana ngesamukeli sesathelayithi esisodwa, kanye nabamukeli besathelayithi abangaphezu kwamabili kanye nama-antenna angaphezu kwamabili abelana. Ngaphezu kwezintambo, ukuxhumana phakathi kwazo kuqashelwa kakhulu yinhlanganisela.

ukuhlela ama-switcher. Umsabalalisi wamandla usetshenziselwa ukuxhuma abamukeli besathelayithi abaningi. Uma isethi yama-antenna idinga ukuxhunywa kubamukeli besathelayithi abaningi, kufanele kusetshenziswe umsabalalisi wamandla. Khetha umsabalalisi wamandla ngokwenani labamukeli abaxhunyiwe. Uma abamukeli ababili bexhunyiwe, kusetshenziswa umsabalalisi wamandla amabili. Xhuma abamukeli abane bese usebenzisa abasabalalisi bamandla abane.

Izinkomba zobuchwepheshe

Izinkomba zobuchwepheshe zomsabalalisi wamandla zifaka phakathi ububanzi bemvamisa, amandla okuthwala, ukulahlekelwa kokusabalalisa kusuka kusekethe eyinhloko kuya egatsheni, ukulahlekelwa kokufakwa phakathi kokufaka nokukhipha, ukuhlukaniswa phakathi kwamachweba egatsha, isilinganiso samagagasi okuma kwe-voltage sechweba ngalinye, njll.

1. Ububanzi bemvamisa. Lesi yisimo sokusebenza samasekethe ahlukahlukene e-RF / microwave. Isakhiwo somklamo womsabalalisi wamandla sihlobene kakhulu nemvamisa yokusebenza. Imvamisa yokusebenza yomsabalalisi kumele ichazwe ngaphambi kokuba kwenziwe umklamo olandelayo

2. Ukumelana namandla. Kumsabalalisi/i-synthesizer enamandla amakhulu, amandla aphezulu kakhulu izingxenye zesekethe ezingawathwala yinkomba eyinhloko, enquma ukuthi yiluphi uhlobo lomugqa wokudlulisela olungasetshenziswa ukufeza umsebenzi wokuklama. Ngokuvamile, ukuhleleka kwamandla athwalwa umugqa wokudlulisela kusukela kokuncane kuya kokukhulu umugqa we-microstrip, umugqa we-strip, umugqa we-coaxial, umugqa we-air strip kanye nomugqa we-air coaxial. Yimuphi umugqa okufanele ukhethwe ngokuya ngomsebenzi wokuklama.

3. Yabela ukulahlekelwa. Ukulahleka kokusatshalaliswa kusuka kusekethe eyinhloko kuya kusekethe yegatsha kuhlobene kakhulu nesilinganiso sokusatshalaliswa kwamandla somsabalalisi wamandla. Isibonelo, ukulahlekelwa kokusatshalaliswa kwama-power divider amabili alinganayo kungu-3dB kanti okwama-power divider amane alinganayo kungu-6dB.

4. Ukulahleka kokufakwa. Ukulahleka kokufakwa phakathi kokufakwayo nokukhishwayo kubangelwa yi-medium engaphelele noma umqhubi womugqa wokudlulisela (njengomugqa we-microstrip), uma kubhekwa ukulahleka okubangelwa yisilinganiso segagasi elimile kokufakwayo.

5. Ukuhlukaniswa. Ukuhlukaniswa phakathi kwamachweba egatsha kungenye inkomba ebalulekile yomsabalalisi wamandla. Uma amandla okufaka avela echwebeni ngalinye legatsha engakhishwa kuphela echwebeni eliyinhloko futhi kungafanele akhishwe kwamanye amagatsha, kudinga ukuhlukaniswa okwanele phakathi kwamagatsha.

6. Isilinganiso samagagasi amile. Uma i-VSWR yechweba ngalinye incane, kungcono.

Iisihlukanisi samandlaingahlukaniswa ngezigaba ezimbili ngokwesakhiwo:

（1） Izici eziyinhloko zesihlukanisi samandla esingasebenzi yilezi: ukusebenza okuzinzile, isakhiwo esilula futhi ngokuyisisekelo akukho msindo; Ububi bayo obukhulu ukuthi ukulahlekelwa kokufinyelela kukhulu kakhulu.

（2） Isihlukanisi samandla asebenzayo sakhiwe nge-amplifier. Izici zaso eziyinhloko yilezi: inzuzo kanye nokuhlukaniswa okuphezulu. Izinkinga zaso eziyinhloko umsindo, isakhiwo esiyinkimbinkimbi kanye nokuzinza kokusebenza okubi. Imbobo yokukhipha yesihlukanisi samandla inamaphuzu amabili kagesi, amaphuzu amathathu kagesi, amaphuzu amane kagesi, amaphuzu ayisithupha kagesi, amaphuzu ayisishiyagalombili kagesi kanye namaphuzu ayishumi nambili kagesi.

Igama eliphelele lesihlukanisi samandla yi-power divider. Iyidivayisi ehlukanisa amandla esignali yokufaka eyodwa ibe yiziteshi ezimbili noma ngaphezulu bese ikhipha amandla alinganayo noma angalingani. Futhi, ingahlanganisa amandla esignali amaningi ibe yi-output eyodwa. Ngalesi sikhathi, ingabizwa nangokuthi i-combiner. Izinga elithile lokuhlukaniswa kufanele liqinisekiswe phakathi kwama-output ports esihlukanisi samandla. Ngokusho kokukhipha, isihlukanisi samandla sivame ukuhlukaniswa sibe yi-single sibe yi-two (input eyodwa kanye ne-outputs ezimbili), esisodwa sibe yi-three (input eyodwa kanye ne-outputs ezintathu), njll. Amapharamitha obuchwepheshe ayinhloko esihlukanisi samandla afaka ukulahlekelwa amandla (kufaka phakathi ukulahlekelwa kokufakwa, ukulahlekelwa kokusabalalisa kanye nokulahlekelwa kokubonakaliswa), isilinganiso samagagasi okuma kwe-voltage se-port ngayinye, ukuhlukaniswa phakathi kwama-output okusabalalisa amandla, ibhalansi ye-amplitude, ibhalansi yesigaba, umthamo wamandla kanye nobubanzi bebhendi yemvamisa.

Singakwazi futhi ukwenza ngezifiso izingxenye ze-rf passive ngokwezidingo zakho. Ungangena ekhasini lokwenza ngezifiso ukuze unikeze imininingwane oyidingayo.
