I-Sichuan Keenlion Microwave Technology Yasekwa ngo-2004, iSichuan Keenlion Mircrowave techenology CO., Ltd. ngumenzi okhokelayo wamacandelo ePassive Mircrowave eSichuan Chengdu, eChina.
Sinikezela ngamacandelo e-mirrowave asebenza kakhulu kunye neenkonzo ezinxulumene noko kwizicelo ze-microwave ekhaya naphesheya. Iimveliso azibizi kakhulu, kubandakanya ukwahlula amandla okwahlukeneyo, ii-couplers ezikhokelayo, izihluzi, izihlanganisi, ii-duplexers, iikhomponenti ezenziwe ngokwezifiso, i-isolator kunye neesetyhula. Iimveliso zethu ziyilelwe ngokukodwa iimeko ezahlukeneyo ezingqongileyo kunye namaqondo obushushu. Iinkcukacha zinokuqulunqwa ngokweemfuno zabathengi kwaye zisebenza kuzo zonke iibhendi eziqhelekileyo kunye nezidumileyo ezinamaza ohlukeneyo ukusuka kwi-DC ukuya kwi-50GHz.

Izixhobo zokwenziwa
Izixhobo zePassive ziyiklasi ebalulekileyo ye-microwave kunye nezixhobo ze-RF, ezidlala indima ebaluleke kakhulu kwi-teknoloji ye-microwave. Amacandelo e-Passive ikakhulu abandakanya izixhasi, ii-capacitors, ii-inductors, iziguquli, ii-gradients, iinethiwekhi ezihambelanayo, ii-resonators, izihluzi, izixube kunye nokutshintsha.

Uhlobo lwesixhobo
Intshayelelo yeentlobo
Amacandelo e-Passive ikakhulu abandakanya izixhasi, ii-capacitors, ii-inductors, iziguquli, ii-gradients, iinethiwekhi ezihambelanayo, ii-resonators, izihluzi, izixube kunye nokutshintsha. Icandelo lombane elingabonisa iimpawu zalo ngaphandle kokunikezelwa kwamandla angaphandle. Amalungu angenakwenziwa ikakhulu zizixhobo ezixhathisayo, inductive kunye ne-capacitive. Isici sabo esiqhelekileyo kukuba banokusebenza xa kukho umqondiso ngaphandle kokongeza amandla kwisiphaluka.

isixhasi
Xa i-current idlula kwi-conductor, ipropati yokuba ukuchasana kwangaphakathi kwe-conductor kuthintela okwangoku kubizwa ngokuba yi-resistance. Amacandelo adlala indima yokuthintela okwangoku kwisekethe ebizwa ngokuba yi-resistors, ebizwa ngokuba yi-resistors ngokufutshane. Injongo ephambili ye-resistor kukunciphisa i-voltage, ukwahlula i-voltage okanye i-shunt. Isetyenziswa njengomthwalo, impendulo, ukudibanisa, ukuhlukaniswa, njl. kwezinye iisekethe ezikhethekileyo.
Isimboli sokumelana nomzobo wesiphaluka unobumba R. Iyunithi esemgangathweni yokuchasana ngu-Ohm, ebhalwe njenge-Ω. Ngokuqhelekileyo zisetyenziswa koohm KΩ kunye ne-megaohm mΩ.
IKΩ=1000Ω 1MΩ=1000KΩ

capacitor
I-Capacitor yenye yezona zinto ziqhelekileyo kwiisekethe ze-elektroniki. Licandelo lokugcina amandla ombane. I-capacitor yenziwe ngabaqhubi ababini abanobukhulu obufanayo kunye nomgangatho odibeneyo kunye noluhlu lwe-insulating medium. Xa i-voltage isetyenziswe kuzo zombini iziphelo ze-capacitor, intlawulo yombane igcinwa kwi-capacitor. Nje ukuba i-voltage ingabikho, okoko nje kukho isekethe evaliweyo, iya kukhupha amandla ombane. I-capacitor ivimbela i-DC ukuba idlule kwisiphaluka kwaye ivumela i-AC ukuba idlule. Okukhona iphezulu i-frequency ye-AC, inamandla amandla okudlula. Ke ngoko, ii-capacitors zihlala zisetyenziswa kwiisekethe zokudibanisa, ukucofa i-bypass, impendulo, ixesha kunye ne-oscillation.
Ikhowudi yeleta ye-capacitor yi-C. Iyunithi ye-capacitance yi-farad (ibhalwe njenge-f), esetyenziswa ngokuqhelekileyo μF (indlela encinci), i-PF (okt μμF. Indlela yePico).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
Iimpawu ze-capacitance kwisiphaluka azifani. I-impedance yangoku ibizwa ngokuba yi-capacitive reactance. I-Capacitive Reactance ihambelana ngokuphambeneyo nomthamo kunye nobuninzi bomqondiso.

Inductor
Njenge-capacitance, i-inductance nayo iyinxalenye yokugcina amandla. Ii-inductors ngokubanzi zenziwe ngeekhoyili. Xa i-voltage ye-AC isetyenziswa kuzo zombini iziphelo zekhoyili, amandla e-electromotive eveliswa kwikhoyili, ethintela ukudlula kwangoku kwikhoyili ekutshintsheni. Lo mqobo ubizwa ngokuba yi-inductive resistance. I-reactance inductive ihambelana ngokuthe ngqo kwi-inductance kunye nokuphindaphinda komqondiso. Ayithinteli i-DC yangoku (kungakhathaliseki ukuxhathisa kwe-DC kwekhoyili). Ke ngoko, indima ye-inductance kwiisekethe ze-elektroniki yile: ukubhloka kwangoku, ukuguqulwa kwamandla ombane, ukudibanisa kunye nokudibanisa kunye ne-capacitance yokulungelelanisa, ukuhluza, ukhetho lwamaza, ulwahlulo lwamaza, njl.
Ikhowudi ye-inductance kwisekethe ngu-L. Iyunithi ye-inductance nguHenry (ebhalwe njenge-H), kunye nezona zisetyenziswa ngokuqhelekileyo ziyi-milliheng (MH) kunye ne-micro Heng (μH).
1H=1000mH 1mH=1000μH
I-inductance licandelo eliqhelekileyo lokungeniswa kwe-electromagnetic kunye nokuguqulwa kwe-electromagnetic. Esona sicelo siqhelekileyo sisiguquli.

Isikhokelo sophuhliso
1. Imodyuli edityanisiweyo yindlela yophuhliso lwexesha elizayo lwamacandelo okwenziwa. Imodyuli yokudibanisa inika amandla okudibanisa amacandelo asebenzayo okanye iimodyuli kunye namacandelo angenayo, kwaye ihlangabezana neemfuno zokunciphisa imodyuli kunye neendleko eziphantsi ngexesha elifanayo. Iindlela eziphambili zibandakanya: itekhnoloji ye-ceramic ephantsi kobushushu obuphantsi (LTCC), itekhnoloji yefilimu encinci, itekhnoloji ye-silicon wafer semiconductor, itekhnoloji yebhodi yesekethe ye-multilayer, njl.
2. Miniaturization. Ukusukela i-miniaturization kunye nekhaphukhaphu kwishishini elingenazingcingo lifuna izixhobo zokwenziwa ukuba ziphuhlise kwicala elincinci. IMicro electro mechanical system (MEMS) isetyenziswa ikakhulu ukwenza amacandelo eRF abe mancinci, abe nexabiso eliphantsi, abe namandla ngakumbi kwaye alungele ngakumbi ukudityaniswa.
3. Impembelelo ye-encapsulation. Xa kuthelekiswa nomgangatho oqhelekileyo osetyenziswayo owenziweyo, ukuhlanganiswa kwamacandelo kwiphakheji kunokuphucula ngokufanelekileyo ukuthembeka kwenkqubo, ukunciphisa indlela yokuqhuba, ukunciphisa imiphumo ye-parasitic, ukunciphisa iindleko kunye nokunciphisa ubungakanani bezixhobo.

Umahluko phakathi kwamalungu asebenzayo kunye nokwenziwa
Izixhobo zePassive zizixhobo ezinokubonisa iimpawu zazo zangaphandle ngokuzimeleyo ngaphandle kobukho bamandla angaphandle (DC okanye AC). Ngaphandle koko, kukho izixhobo ezisebenzayo. Into ebizwa ngokuba "yimpawu yangaphandle" kukuchaza ubuninzi bobudlelwane besixhobo, nangona amandla ombane okanye angoku, intsimi yombane okanye intsimi yemagnethi, uxinzelelo okanye isantya kunye nezinye izixa zisetyenziselwa ukuchaza ubudlelwane bayo.

Sisenokwenza ngokwezifiso amalungu e-rf passive ngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
