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.

A bi directional crossguide coupler ndi gawo lomwe limayika mizere iwiri yotumizirana moyandikana kuti mphamvu pa mzere umodzi uphatikizidwe ndi inzake. Coupler imafananizidwa ndi mawonekedwe olepheretsa pamadoko onse anayi, zomwe zimapangitsa kuti zikhale zosavuta kuyika mabwalo ena kapena ma subsystems. Potengera mawonekedwe osiyanasiyana olumikizirana, ma media olumikizirana, ndi njira zolumikizirana, ma coaial single directional crossguide couplers oyenera makina osiyanasiyana a microwave okhala ndi zofunikira zosiyanasiyana amatha kupangidwa.

Kugwiritsa ntchito pafupipafupi single directional crossguide coupler:

Microwave single directional crossguide 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 yambiri.
1. Mu amplifier yolinganiza, rf single directional crossguide coupler imathandizira kukwaniritsa bwino input-output voltage Stand wave ratio (VSWR).
2. Mu zosakaniza zoyenerera ndi zida za ma microwave (monga zowunikira maukonde), ma millimeter wave single directional crossguide coupler angagwiritsidwe ntchito kuyesa zochitika ndi ma siginecha owonetseredwa.
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 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. Ma radio frequency single directional crossguide couplers amagwiritsidwa ntchito kwambiri pamapulogalamu ambiri.
Takulandirani makasitomala kuti muyimbire ndikufunsa.
