Cholumikizira cha Waveguide cholunjika chimodzi chimakhala ndi ma waveguide awiri olunjika kumanja.

Kulumikiza kumachitika poyambitsa mabowo awiri ang'onoang'ono pakhoma lalikulu la waveguide. Pambuyo pa kapangidwe koyenera, mphamvu ya chizindikiro yolumikizidwa kudzera m'mabowo awiriwa olumikizira imatha kubwezeretsedwa ndikuchotsedwa. Mabowo awa nthawi zambiri amapangidwa kukhala dzenje laling'ono lopingasa kuti akwaniritse bwino ntchito.

Cholumikizira cha magiya awiri cholumikizirana ndi mbali imodzi chomwe chimayika mizere iwiri yotumizira pafupi kuti mphamvu pamzere umodzi ilumikizane ndi inayo. Cholumikiziracho chimagwirizana ndi impedance yodziwika bwino pamadoko onse anayi, zomwe zimapangitsa kuti zikhale zosavuta kuziyika m'mabwalo ena kapena ma subsystem ena. Mwa kugwiritsa ntchito njira zosiyanasiyana zolumikizirana, ma coupling media, ndi ma coupling mechanisms, ma coupling a coaial single directional crossguide coupling oyenerera machitidwe osiyanasiyana a microwave okhala ndi zofunikira zosiyanasiyana akhoza kupangidwa.

Kugwiritsa ntchito cholumikizira cha crossguide cholumikizira chapamwamba kwambiri:

Ma microwave single directional crossguide couplers, monga gawo lofunikira la ma microwave circuits ambiri, amagwiritsidwa ntchito kwambiri m'makina amakono amagetsi. Angagwiritsidwe ntchito kupereka mphamvu yoyesera kuti achepetse kutentha ndi ma amplitude control circuits, ndipo amatha kugawa mphamvu ndi kupanga mphamvu pa ma frequency osiyanasiyana.
1. Mu amplifier yolinganizidwa bwino, cholumikizira cha rf single directional crossguide chimathandiza kupeza chiŵerengero chabwino cha mafunde okhazikika a input-output (VSWR).
2. Mu zida zosakaniza bwino ndi zida za microwave (monga zowunikira maukonde), cholumikizira cha millimeter wave single directional crossguide chingagwiritsidwe ntchito kuyesa zizindikiro zamwadzidzidzi ndi zowunikira.
3. Mu kulumikizana kwa mafoni, kugwiritsa ntchito cholumikizira cha 90 ° bridge kumatha kudziwa cholakwika cha gawo la chotumizira cha π/4 phase shift keying (QPSK).

Qualwaveimapereka ma couplers a broadband amphamvu kwambiri okhala ndi ma single directional crossguide osiyanasiyana kuyambira 1.13 mpaka 40GHz. Pali mitundu yosiyanasiyana ya ma waveguide ports, monga WR-28 ndi WR-34. Ma radio frequency single directional crossguide couplers amagwiritsidwa ntchito kwambiri m'njira zambiri.
Takulandirani makasitomala kuti ayimbire foni ndikufunsa mafunso.
