Izindaba

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 samandlaiyidivayisi ehlukanisa isignali eyodwa yokufaka ibe yimiphumela yamandla emibili noma ngaphezulu elinganayo
ngokwesakhiwo ihlukaniswe ngezigaba ezimbili:
（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.
Iyidivayisi ehlukanisa amandla esignali yokufaka eyodwa ibe yiziteshi ezimbili noma ngaphezulu bese ikhipha amandla alinganayo noma angalingani. Futhi, ingahlanganisa amandla esignali amaningi ibe umkhiqizo owodwa. Ngalesi sikhathi, ingabizwa nangokuthi i-combiner. Izinga elithile lokuhlukaniswa kufanele liqinisekiswe phakathi kwama-port okukhiphayo kwesihlukanisi samandla. Ngokusho kokukhiphayo, isihlukanisi samandla sivame ukuhlukaniswa sibe yi-one in two (okufakwayo okukodwa kanye nokukhishwa okubili), eyodwa in three (okufakwayo okukodwa kanye nokukhishwa okuthathu), njll. Amapharamitha obuchwepheshe ayinhloko esihlukanisi samandla ukulahlekelwa amandla (kufaka phakathi ukulahlekelwa kokufakwa, ukulahlekelwa kokusabalalisa kanye nokulahlekelwa kokubonakaliswa), isilinganiso samagagasi okuma kwe-voltage se-port ngayinye, ukuhlukaniswa phakathi kwama-port okusabalalisa amandla, ibhalansi ye-amplitude, ibhalansi yesigaba, umthamo wamandla kanye ne-bandwidth, njll.
Izinkomba zobuchwepheshe
Izinkomba zobuchwepheshe zesihlukanisi samandla zifaka phakathi ububanzi bemvamisa, amandla okuthwala, ukulahlekelwa kokusatshalaliswa 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 sezifunda ezahlukene ze-RF / microwave. Isakhiwo somklamo womsabalalisi wamandla sihlobene kakhulu nemvamisa yokusebenza. Imvamisa yokusebenza yomsabalalisi kumele ichazwe ngaphambi kokuba kwenziwe umklamo olandelayo.
2. Amandla okuthwala: ku-distributor/synthesizer enamandla amakhulu, amandla aphezulu kakhulu i-element yesekethe engawathwala yi-core index, 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. Ukulahleka kokusabalalisa: ukulahleka kokusabalalisa kusuka kusekethe eyinhloko kuya kusekethe yegatsha kuhlobene kakhulu nesilinganiso sokusabalalisa amandla somsabalalisi wamandla. Isibonelo, ukulahleka kokusabalalisa kwama-power divider amabili alinganayo kungu-3dB kanti okwama-power divider amane alinganayo kungu-6dB.
4. Ukulahlekelwa kokufakwa: ukulahleka kokufakwa phakathi kokufakwayo nokukhishwayo kubangelwa yi-dielectric engaphelele noma umqhubi womugqa wokudlulisela (njengomugqa we-microstrip) kanye nokucabangela isilinganiso samagagasi amile ekugcineni kokufakwayo.
5. Izinga lokuhlukaniswa: izinga lokuhlukaniswa phakathi kwamachweba egatsha lingenye 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. I-VSWR: uma i-VSWR yechweba ngalinye incane, kungcono kakhulu.

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