Sichuan Keenlion Microwave Technology E Thehiloe ka 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ke moetsi ea ka sehloohong oa likarolo tsa Passive Mircrowave Sichuan Chengdu, Chaena.
Re fana ka lisebelisoa tsa mirrowave tse sebetsang hantle haholo le lits'ebeletso tse amanang le tsona bakeng sa lits'ebetso tsa microwave lapeng le kantle ho naha. Lihlahisoa li na le litšenyehelo tse ngata, ho kenyelletsa le likarohano tse fapaneng tsa matla, li-couplers tse tataisang, li-filters, li-componder, li-duplexer, likaroloana tse ikhethileng, li-isolators le li-circulator. Lihlahisoa tsa rona li etselitsoe ka ho khetheha maemo a fapaneng a feteletseng le mocheso. Litlhaloso li ka etsoa ho latela litlhoko tsa bareki 'me li sebetsa ho lihlopha tsohle tse tloaelehileng le tse tsebahalang tse nang le li-bandwidth tse fapaneng ho tloha ho DC ho ea ho 50GHz.
coupler
Karolo ea kabo ea matla bakeng sa ho arola lets'oao la RF ka liteishene tse peli ka ho lekana le ho le fetisetsa ho sistimi ea phepelo ea antenna.

Lisebelisoa tse ka sehloohong
(1) Tšebeliso ea potoloho ea logic
The coupler e ka theha lipotoloho tse fapaneng tsa logic. Hobane ts'ebetso e khahlanong le ho kena-kenana le ho itšehla thajana ea coupler e molemo ho feta ea transistor, potoloho ea logic e entsoeng ke eona e ka tšeptjoa haholoanyane.
Libaka tsa kopo le liketsahalo tsa coupler
(2) Kopo e le sesebelisoa sa boemo bo tiileng
Sebakeng sa ho fetola, hangata ho hlokahala hore ho be le karohano e ntle ea motlakase pakeng tsa potoloho ea taolo le sesebelisoa, e leng ntho e thata bakeng sa sesebelisoa se akaretsang sa elektronike, empa ho bonolo ho se hlokomela le coupler.
(3) Kopo ea potoloho ea trigger
Ha coupler e sebelisoa potolohong ea lihlahisoa tsa bistable, bothata ba ho itšehla thajana pakeng tsa tlhahiso le mojaro bo ka rarolloa ka katleho hobane LED e ka kopanngoa ka letoto ho potoloho ea emitter ea li-tubes tse peli ka ho latellana.
(4) Kopo ho potoloho ea pulse amplification
Banyalani ba sebelisoa lipotolohong tsa dijithale ho holisa mats'oao a pulse.
(5) Kopo ka potoloho ea mola
Linear coupler e sebelisoa potolohong ea linear, e nang le linearity e phahameng le ts'ebetso e ntle ea ho itšehla thajana ea motlakase.
(6) Kopo liketsahalong tse khethehileng
The coupler e ka boela ea sebelisoa ho laola motlakase o phahameng, ho nkela transformer sebaka, ho nkela sebaka sa puisano le potoloho ea A / D.

Lipontšo tsa tekheniki
1. Tekanyo ea ho kopanya: phapang e tobileng pakeng tsa matla a hlahisoang ho tloha ho coupling port le matla a pontšo ea ho kenya ha matla a pontšo a feta ka coupler.
2. Tekanyo ea ho itšehla thajana: e bolela ho itšehla thajana pakeng tsa boema-kepe ba tlhahiso le koung ea ho kopanya; Ka kakaretso, index ena e sebelisoa feela ho lekanya microstrip coupler. 'Me e fapana ho ea ka tekanyo ea ho kopanya: mohlala, 5-10db ke 18 ~ 23dB, 15dB ke 20 ~ 25dB, le 20dB (ho kenyeletsoa ka holimo) ke 25 ~ 30dB; tekanyo ea ho itšehla thajana ea "cavity coupler" e ntle haholo, kahoo ha ho na tlhoko ea index ena.
3. Directivity: e bua ka boleng ba ho itšehla thajana pakeng tsa boema-kepe ba tlhahiso le koung ea ho kopanya ho tlosa boleng ba tekanyo ea ho kopanya. Kaha directivity ea microstrip e fokotseha butle-butle ka keketseho ea tekanyo ea ho kopanya, ha e le hantle ha ho na directivity ka holimo ho 30dB, kahoo ha ho na tlhokahalo e joalo ea index bakeng sa banyalani ba microstrip. The directivity ea cavity coupler ka kakaretso 17 ~ 19dB ho 1700 ~ 2200MHz, 824 ～ 960MHz: 18 ~ 22dB.
4. Mokhoa oa ho bala: directivity = ho itšehla thajana - ho kopanya.
5. Tahlehelo ea ho kenya: e bolela boleng bo fumanoeng ka ho tlosa boleng ba tahlehelo ea kabo ho tloha ho matla a lets'oao a fokotsehileng ho tloha matleng a lets'oao ho ea ho sephetho. Ka kakaretso, tahlehelo ea ho kenya microstrip coupler e fapana ho ea ka tekanyo ea ho kopanya. Ka kakaretso, ke 0.35 ~ 0.5dB ka tlase ho 10dB le 0.2 ~ 0.5dB ho feta 10dB.
6. Karo-karolelano ea maqhubu a ho kenya / tlhahiso: e bua ka ho bapisa ha likou tsa ho kenya / tse hlahisoang, 'me litlhoko tsa koung ka' ngoe hangata ke 1.2 ~ 1.4;
7. Mamello ea matla: e bua ka mamello e kholo ea matla a ho sebetsa e ka fetang ka banyalani bana ka nako e telele (ntle le tšenyo). Ka kakaretso, matla a karolelano ea microstrip coupler ke 30 ~ 70W, 'me ea cavity ke 100 ~ 200W.
8. Maqhubu a maqhubu: ka kakaretso, lebelo la lebitso ke 800 ~ 2200MHz. Ebile, sehlopha sa maqhubu a hlokahalang ke 824-960MHz hammoho le 1710 ~ 2200MHz. Leqhubu la maqhubu a mahareng ha le fumanehe.
9. In band Flatness: e bolela phapang pakeng tsa tekanyo e phahameng le e fokolang ea ho kopanya sehlopheng kaofela se fumanehang sa maqhubu. Microstrip hangata ke 0.5 ~ 0.2db. Cavity: kaha degree ea coupling ke curve, ha ho na tlhoko e joalo.

Re ka boela ra etsa likarolo tsa rf passive ho latela litlhoko tsa hau. U ka kenya leqephe la ho itlhophisa ho fana ka lintlha tseo u li hlokang.
