Waveguide single directional crossguide coupler imakhala ndi ma waveguide awiri akumanja.

Kulumikizana kumatheka poyambitsa mabowo ang'onoang'ono awiri pakhoma lalikulu la waveguide. Pambuyo pakupanga kukhathamiritsa, mphamvu ya siginecha yolumikizidwa kudzera m'mabowo awiri olumikizirawa imatha kusinthidwa ndikuchotsedwa. Mabowowa nthawi zambiri amapangidwa kukhala kabowo kakang'ono kuti akwaniritse ntchito yabwino.

Cholumikizira chowongolera ndi gawo lomwe limayika mizere iwiri yotumizira moyandikana kuti mphamvu pamzere umodzi uphatikizidwe ndi imzake. Coupler imafananizidwa ndi mawonekedwe olepheretsa pamadoko onse anayi, zomwe zimapangitsa kuti zikhale zosavuta kuyika mabwalo ena kapena ma subsystems. Pakutengera mitundu yosiyanasiyana yolumikizirana, kuphatikiza media, ndi njira zolumikizirana, zolumikizira zolozera zoyenera kumakina osiyanasiyana a microwave okhala ndi zofunikira zosiyanasiyana zitha kupangidwa.

Ntchito:

Ma Directional couplers, monga gawo lofunikira pamabwalo ambiri a microwave, amagwiritsidwa ntchito kwambiri pamakina amakono amagetsi. Itha kugwiritsidwa ntchito popereka zitsanzo zamphamvu zolipirira kutentha ndi mabwalo owongolera matalikidwe, ndipo imatha kumaliza kugawa mphamvu ndi kaphatikizidwe pamitundu yosiyanasiyana.
1. Mu amplifier yoyenerera, imathandizira kukwaniritsa chiŵerengero chabwino cha input-output voltage Stand wave ratio (VSWR).
2. Mu makina osakaniza ndi ma microwave (monga ma analyzer a network), angagwiritsidwe ntchito kuyesa zochitika ndi zizindikiro zowonetsera.
3. Pakulankhulana kwa pa foni yam'manja, kugwiritsa ntchito 90 ° bridge coupler kungadziwe cholakwika cha π/4 phase shift keying (QPSK) transmitter.

Qualwaveimapereka ma Broadband ndi ma high power single directional crossguide couplers osiyanasiyana kuchokera ku 1.13 mpaka 40GHz. Pali mitundu yosiyanasiyana ya madoko a waveguide, monga WR-28 ndi WR-34. The couplers chimagwiritsidwa ntchito ambiri ntchito.
Takulandirani makasitomala kuti muyimbire ndikufunsa.
