Coupler ndi chipangizo chomwe chimagwiritsidwa ntchito potumiza ma siginecha pakati pa mabwalo kapena makina osiyanasiyana. Amagwiritsidwa ntchito kwambiri pamawayilesi a wailesi ndi ma microwave. Ntchito yake yayikulu ndikuphatikiza gawo lina la mphamvu kuchokera pamzere waukulu wotumizira kupita ku mzere wachiwiri kuti mukwaniritse kugawa, kuyang'anira kapena kuyankha.
Momwe coupler imagwirira ntchito
Maanja nthawi zambiri amakhala ndi mizere yopatsirana kapena ma waveguide, omwe amasamutsa gawo la mphamvu yama siginecha mumzere waukulu kupita ku doko lolumikizira kudzera pamakina amagetsi amagetsi. Kuphatikizika kumeneku sikungakhudze kwambiri kutumiza kwa chizindikiro kwa mzere waukulu, kuonetsetsa kuti dongosololi likuyenda bwino.
Main mitundu ya couplers
Directional Coupler: Ili ndi madoko anayi ndipo imatha kuphatikiza gawo la siginecha molunjika ku doko linalake lotuluka kuti liwunikire ma siginecha ndikuwongolera mayankho.
Power Divider: Imagawira ma siginecha olowera kumadoko angapo otulutsa molingana, omwe amagwiritsidwa ntchito nthawi zambiri m'magulu a tinyanga ndi makina amakanema ambiri.
Hybrid Coupler: Itha kugawa siginecha yolowera muzizindikiro zingapo zotulutsa za matalikidwe ofanana koma magawo osiyanasiyana. Amagwiritsidwa ntchito kwambiri m'magawo osinthira ndi ma amplifiers oyenerera.
Zofunikira zazikulu za coupler
Coupling Factor: Imawonetsa chiŵerengero cha mphamvu ya siginecha yomwe imalandiridwa ndi doko lolumikizira ku mphamvu yolowera, yomwe nthawi zambiri imawonetsedwa mu ma decibel (dB).
Kudzipatula: Kumayesa kuchuluka kwa chizindikiro chodzipatula pakati pa madoko osagwiritsidwa ntchito. Kukwera kudzipatula, kumachepetsa kusokoneza pakati pa madoko.
Kutayika Kwakulowetsa: kumatanthauza kutaya mphamvu pamene chizindikiro chikudutsa pa coupler. Kutsika kwa kutayika koyikirako, kumapangitsanso kufalikira kwa ma signal.
Standing wave ratio (VSWR): ikuwonetsa kufananiza kwa doko la coupler. Kuyandikira kwa VSWR ndi 1, kumapangitsanso magwiridwe antchito abwinoko.
Ntchito magawo a couplers
Kuyang'anira ma Signal: M'makina a ma radio frequency, ma couplers amagwiritsidwa ntchito kuchotsa mbali ya sigino kuti iwunikire ndi kuyeza popanda kukhudza kutumiza kwa siginecha yayikulu.
Kugawa kwamagetsi: Pagulu la tinyanga, ma coupler amagwiritsidwa ntchito kugawa ma siginecha mofanana kuzinthu za mlongoti kuti akwaniritse kuwongolera ndi kuwongolera.
Kuwongolera kwamayankho: M'mabwalo amplifier, ma couplers amagwiritsidwa ntchito kuchotsa gawo lina la siginecha ndikulibwezera ku zomwe zalowetsedwa kuti zikhazikike kupindula ndikuwongolera mzere.
Kuphatikizika kwa ma Signal: M'makina olankhulirana, ma couplers atha kugwiritsidwa ntchito kupanga ma siginali angapo kukhala siginecha imodzi kuti ifalitse ndi kukonza mosavuta.
Kupita patsogolo kwaukadaulo kwaposachedwa
Ndi chitukuko chofulumira cha ukadaulo wolumikizirana, zofunikira za magwiridwe antchito a ma couplers potengera ma frequency apamwamba, mphamvu yayikulu komanso bandwidth yayikulu zikuchulukirachulukira. M'zaka zaposachedwa, zinthu za coupler zochokera ku zipangizo zatsopano ndi njira zatsopano zakhala zikuwonekera, ndikutayika kocheperako, kudzipatula kwapamwamba komanso gulu lafupipafupi la maulendo ogwiritsira ntchito, kukwaniritsa zosowa za 5G mauthenga, makina a radar, mauthenga a satana ndi zina.
Pomaliza
Monga gawo lofunikira pamakina a RF ndi ma microwave, ma couplers amatenga gawo lofunikira pakufalitsa, kugawa ndi kuwunika. Kumvetsetsa mfundo yake yogwirira ntchito, mtundu, magawo ofunikira ndi madera ogwiritsira ntchito kumathandizira kusankha koyenerana komanso kukhathamiritsa magwiridwe antchito pama projekiti enieni.
