Ma ke kahua o ka RF a me ka hoʻouna ʻana i ka hōʻailona microwave, ma kahi o ka hoʻouna ʻana i nā hōʻailona uila, ʻo ka hapa nui o lākou e koi i nā laina hoʻouna no ka lawe ʻana i ka hōʻailona, me nā laina coaxial a me nā alakaʻi nalu i hoʻohana nui ʻia e hoʻouna i ka ikehu RF microwave.
Loaʻa i nā laina hoʻouna Waveguide nā pōmaikaʻi o ka conductor haʻahaʻa a me nā poho dielectric, ka mana mana nui, ʻaʻohe poho radiation, ka hana maʻalahi, a me ka hana maʻalahi.ʻO nā alakaʻi nalu i hoʻohana pinepine ʻia, ʻo ia ka rectangular, circular, single ridged, double ridged, a me elliptical.I kēia manawa, ʻo nā alakaʻi nalu i hoʻohana nui ʻia he mau alakaʻi hawewe rectangular.
Ma ke kaʻina noi o nā mea alakaʻi nalu, pono e hoʻopili pinepine ʻia nā mea he nui, a ʻo ka pilina ma waena o nā mea alakaʻi nalu pili e loaʻa pinepine ʻia ma o ka pilina pili o nā flanges.
E like me nā mea hoʻohui coaxial RF, ua hoʻohālikelike ʻia nā alakaʻi nalu maʻamau a me nā flanges ma ke ao holoʻokoʻa.Ma o ka papa ma lalo nei, hiki iā ʻoe ke nīnau i nā inoa maʻamau a me nā nui like ʻole o nā alakaʻi nalu.
Noi o ka Waveguide Coaxial Converter
Pēlā nō, ʻo nā laina coaxial ka laina hoʻouna maʻamau i hoʻohana ʻia i ka microwave a me ka ʻenekini alapine radio, me nā hiʻohiʻona broadband e hiki ke hana mai ke au pololei a hiki i ka millimeter wave band, a i ʻole ke kiʻekiʻe.Ua hoʻohana nui ʻia nā laina hoʻouna coaxial i nā ʻōnaehana microwave a me nā ʻāpana microwave.
Nui nā ʻokoʻa i ka nui, nā mea, a me nā ʻano hoʻoili ma waena o nā laina hoʻouna coaxial a me waveguide.Eia nō naʻe, ma muli o kā lākou ākea ākea, ʻike pinepine nā mea ʻenekinia RF i nā kūlana kahi e pono ai e hoʻopili ʻia nā laina hoʻouna ʻelua, e koi ana i nā mea hoʻololi coaxial waveguide.
ʻO nā mea huli hawewe coaxial nā mea pono i nā lako microwave, ana microwave, ʻōnaehana microwave, a me ka ʻenekinia.ʻO kā lākou mau ʻano hoʻololi, ʻo ia ka hoʻopili ʻana i nā puka liʻiliʻi, ka hoʻopili ʻana i ka ʻimi, ka hoʻololi ʻana o ka laina hope, a me ka hoʻohuli ʻana i ka hawewe nalu;ʻO ka coaxial probe coupling kahi ala hoʻololi i hoʻohana nui ʻia ma waena o lākou.
ʻO ka waveguide coaxial converter ka nui o ka mea hoʻololi mua, ka lua o ka mea hoʻololi, a me ka flange, me nā ʻāpana ʻekolu i hoʻopili ʻia i ke kaʻina.Aia nā mea hoʻololi coaxial orthogonal 90 ° a hoʻopau i nā mea hoʻololi coaxial 180 °.Loaʻa i ka mea huli hawewe coaxial nā hiʻohiʻona o ka pā alapine ākea, ka poho hoʻokomo haʻahaʻa, a me ka nalu kū liʻiliʻi.He ākea ka bandwidth o ka laina coaxial a me ka nalu i ka wā e hoʻouna ai i kēlā me kēia, a ʻo ka bandwidth ma hope o ka hoʻopili ʻana e pili ana i ka hoʻohālikelike ʻana i ke ʻano impedance o ka nalu coaxial.
Hoʻohana maʻamau ka hoʻololi ʻana i ka hawewe coaxial i nā ʻōnaehana microwave, e like me nā antennas, transmitters, receivers, a me nā mea lawe pahu pahu, hiki ke hoʻohana nui ʻia i ke kamaʻilio ukali, radar, kamaʻilio uila, ʻenehana microwave, hoʻāʻo microwave a me nā ʻōnaehana ana, nā ʻōnaehana microwave lapaʻau. , etc.
