E PILI I KĒIA MANAWA

ʻO ka mea hoʻohui alakaʻi kea hoʻokahi Waveguide he ʻelua mau alakaʻi nalu ʻākau.

Hoʻokō ʻia ka hoʻopili ʻana ma ka hoʻomaka ʻana i ʻelua mau lua liʻiliʻi ma ka paia ākea o ka waveguide. Ma hope o ka hoʻolālā hoʻonui ʻana, hiki ke hoʻohuli ʻia a hoʻopau ʻia ka mana hōʻailona i hoʻopili ʻia ma o kēia mau lua hoʻopili ʻelua. Hana pinepine ʻia kēia mau lua i loko o kahi lua keʻa liʻiliʻi e hoʻokō ai i ka hana kūpono.

ʻO kahi coupler crossguide bi directional kahi ʻāpana e kau ana i ʻelua mau laina hoʻoili kokoke i hiki ke hoʻopili ʻia ka mana ma kekahi laina i kekahi. Hoʻohālikelike ʻia ka coupler i ka impedance hiʻohiʻona ma nā awa ʻehā a pau, e maʻalahi ai ke hoʻokomo ʻia i loko o nā kaapuni a i ʻole nā ʻōnaehana liʻiliʻi. Ma ka hoʻohana ʻana i nā ʻano hoʻopili like ʻole, nā mea hoʻopili, a me nā ʻano hana hoʻopili, hiki ke hoʻolālā ʻia nā coupler crossguide hoʻokahi directional coaial i kūpono no nā ʻōnaehana microwave like ʻole me nā koi like ʻole.

Ka hoʻohana ʻana o ka coupler crossguide kuhikuhi hoʻokahi kiʻekiʻe:

ʻO nā mea hoʻohui alakaʻi kuhikuhi hoʻokahi o ka microwave, ma ke ʻano he ʻāpana koʻikoʻi o nā kaapuni microwave he nui, ua hoʻohana nui ʻia i nā ʻōnaehana uila hou. Hiki ke hoʻohana ʻia e hāʻawi i ka mana laʻana no ka uku mahana a me nā kaapuni kaohi amplitude, a hiki ke hoʻopau i ka hoʻokaʻawale mana a me ka synthesis ma luna o kahi ākea alapine ākea.
1. I loko o kahi amplifier kaulike, kōkua ka rf single directional crossguide coupler i ka hoʻokō ʻana i ka input-output voltage standing wave ratio maikaʻi (VSWR).
2. I loko o nā mea hoʻohuihui kaulike a me nā mea hana microwave (e like me nā mea kālailai pūnaewele), hiki ke hoʻohana ʻia ka millimeter wave single directional crossguide coupler e laʻana i nā hōʻailona hanana a me nā hōʻailona i hōʻike ʻia.
3. I ke kamaʻilio kelepona, hiki i ka hoʻohana ʻana i kahi mea hoʻohui alahaka 90 ° ke hoʻoholo i ka hewa pae o kahi mea hoʻoili π/4 phase shift keying (QPSK).

Qualwavehoʻolako i nā mea hoʻohui alakaʻi kuhikuhi hoʻokahi mana kiʻekiʻe ma ka laulā ākea mai 1.13 a 40GHz. Aia nā ʻano like ʻole o nā awa alakaʻi nalu, e like me WR-28 a me WR-34. Hoʻohana nui ʻia nā mea hoʻohui alakaʻi kuhikuhi hoʻokahi alapine lekiō i nā noi he nui.
Welina mai i nā mea kūʻai aku e kāhea a nīnau.
