Sichuan Keenlion Microwave Technology——Passive devices

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.

Lisebelisoa tse sa sebetseng
Lisebelisoa tsa Passive ke sehlopha sa bohlokoa sa lisebelisoa tsa microwave le RF, tse bapalang karolo ea bohlokoa haholo theknoloji ea microwave. Likarolo tse sa sebetseng haholo li kenyelletsa li-resistors, li-capacitor, li-inductors, li-converter, li-gradients, marang-rang a tšoanang, li-resonator, li-filters, li-mixer le li-switches.

Mofuta oa sesebelisoa
Selelekela sa mefuta
Likarolo tse sa sebetseng haholo li kenyelletsa li-resistors, li-capacitor, li-inductors, li-converter, li-gradients, marang-rang a tšoanang, li-resonator, li-filters, li-mixer le li-switches. Karolo ea elektronike e ka bontšang litšobotsi tsa eona ntle le matla a ka ntle. Likarolo tse sa sebetseng ke lisebelisoa tse hanyetsanang haholo, tse inductive le capacitive. Tšobotsi ea bona e tloaelehileng ke hore ba ka sebetsa ha ho e-na le letšoao ntle le ho eketsa matla a potoloho.

mohanyetsi
Ha hona joale ho feta mokhanni, thepa eo khanyetso ea ka hare ea mokhanni e sitisang hona joale e bitsoa ho hanyetsa. Likarolo tse phethang karolo ea ho thibela hona joale potolohong li bitsoa li-resistors, tse bitsoang li-resistors ka nako e khutšoanyane. Sepheo se seholo sa resistor ke ho fokotsa motlakase, ho arola voltage kapa shunt. E sebelisoa e le mojaro, maikutlo, ho kopanya, ho itšehla thajana, joalo-joalo lipotolohong tse ling tse khethehileng.
Letšoao la ho hanyetsa setšoantšong sa potoloho ke lengolo R. Sehlopha se tloaelehileng sa ho hanyetsa ke Ohm, se tlalehiloeng e le Ω. Tse sebelisoang hangata ke kiloohm KΩ le megaohm mΩ.
IKΩ=1000Ω 1MΩ=1000KΩ

capacitor
Capacitor hape ke e 'ngoe ea likarolo tse atileng haholo lipotolohong tsa elektroniki. Ke karolo ea ho boloka matla a motlakase. Capacitor e entsoe ka li-conductors tse peli tsa boholo bo lekanang le boleng bo kentsoeng ka lera la insulating medium. Ha motlakase o sebelisoa lipheletsong tse peli tsa capacitor, tefiso ea motlakase e bolokiloe ho capacitor. Hang ha ho se na motlakase, hafeela ho na le potoloho e koetsoeng, e tla lokolla matla a motlakase. Capacitor e thibela DC ho feta potolohong mme e lumella AC hore e fete. Ha maqhubu a AC a phahame, matla a ho feta a matla. Ka hona, li-capacitor li atisa ho sebelisoa lipotolohong bakeng sa ho kopanya, ho sefa, ho fana ka maikutlo, nako le oscillation.
Khoutu ea lengolo la capacitor ke C. Sehlopha sa capacitance ke farad (e tlalehiloeng e le f), e atisang ho sebelisoa μF (mokhoa o monyenyane), PF (ke hore μμF. Pico mokhoa).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
Litšobotsi tsa capacitance ka potoloho ke nonlinear. The impedance to current e bitsoa capacitive reactance. Capacitive reactance e fapana ka tsela e fapaneng le matla le maqhubu a mats'oao.

Inductor
Joalo ka capacitance, inductance le eona ke karolo ea polokelo ea matla. Hangata li-inductors li entsoe ka likhoele. Ha motlakase oa AC o sebelisoa lipheletsong tse peli tsa coil, matla a electromotive a susumelitsoeng a hlahisoa ka har'a coil, e thibelang hore hona joale ho fete ka khoele ho se fetohe. Tšitiso ena e bitsoa inductive resistance. The inductive reactance e lekana ka kotloloho le inductance le khafetsa ea lets'oao. Ha e sitise DC hona joale (ho sa tsotellehe ho hanyetsa ha DC ha coil). Ka hona, karolo ea inductance ho li-circuits tsa elektroniki ke: ho thibela hona joale, phetoho ea motlakase, ho kopanya le ho tsamaisana le bokhoni ba ho hlophisa, ho sefa, khetho ea khafetsa, karohano ea maqhubu, jj.
Khoutu ea inductance potolohong ke L. Sehlopha sa inductance ke Henry (e tlalehiloeng e le H), 'me tse sebelisoang hangata ke milliheng (MH) le micro Heng（μH).
1H=1000mH 1mH=1000μH
Inductance ke karolo e tloaelehileng ea induction ea electromagnetic le phetoho ea motlakase. Sesebelisoa se tsebahalang haholo ke transformer.

Tataiso ea ntlafatso
1. Integrated modularization ke mokhoa oa nakong e tlang oa ntshetsopele ea likarolo tse sa sebetseng. Mojule oa ho kopanya o fana ka bokhoni ba ho kopanya likarolo tse sebetsang kapa li-module le likarolo tse sa sebetseng, 'me o finyella litlhoko tsa ho fokotsa li-module le litšenyehelo tse tlaase ka nako e le' ngoe. Mekhoa e ka sehloohong e kenyelletsa: thekenoloji ea mocheso o tlase oa mocheso o chesang oa ceramic (LTCC), theknoloji e tšesaane ea filimi, theknoloji ea silicon wafer semiconductor, theknoloji ea multilayer circuit board, joalo-joalo.
2. Miniaturization. Ho lelekisa miniaturization le bobebe indastering e se nang mohala ho hloka lisebelisoa tse sa sebetseng hore li hole ka tsela e nyane. Micro electro mechanical system (MEMS) e sebelisoa haholo-holo ho etsa hore likarolo tsa RF li be nyane, li theko e tlase, li be matla le ho thusa ho kopanya.
3. Phello ea encapsulation. Ha ho bapisoa le lisebelisoa tse tloaelehileng tse sebelisoang holim'a metsi, ho kopanngoa ha likarolo ka har'a sephutheloana ho ka ntlafatsa ho tšepahala ha tsamaiso ka katleho, ho khutsufatsa tsela ea ho khanna, ho fokotsa liphello tsa likokoana-hloko, ho fokotsa litšenyehelo le ho fokotsa boholo ba lisebelisoa.

Phapang lipakeng tsa likarolo tse sebetsang le tse sa sebetseng
Lisebelisoa tsa Passive ke lisebelisoa tse ka bonts'ang litšoaneleho tsa tsona tsa kantle ka boits'oaro ntle le ho ba teng ha matla a kantle (DC kapa AC). Ho feta moo, ho na le lisebelisoa tse sebetsang. Seo ho thoeng ke "tšobotsi ea ka ntle" ke ho hlalosa palo e itseng ea kamano ea sesebelisoa, le hoja motlakase kapa hona joale, matla a motlakase kapa matla a khoheli, khatello kapa lebelo le tse ling tse ngata li sebelisoa ho hlalosa kamano ea eona.

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.
