RF Cable Introduction

Ma waho aʻe o ke alapine, ka lākiō hawewe kū, ka nalowale o ka hoʻokomo ʻana a me nā mea ʻē aʻe, ʻo ke koho pololei ʻana o nā ʻāpana RF cable pono e noʻonoʻo pono i nā ʻano mechanical o ke kaula, ka ʻenehana hana a me nā koi noi, ʻo ia hoʻi, ʻo ke kumukūʻai he mea hoʻololi mau. .

Ma kēia pepa, e kūkākūkā nui ʻia nā ʻano kuhikuhi like ʻole a me ka hana o ke kelepona RF.He mea maikaʻi loa ka ʻike ʻana i ka hana o ke kaula no ke koho ʻana i ka hui kelepona RF maikaʻi loa.

Koho uwea
Hoʻohana ʻia ke kaula coaxial Rf e hoʻouna i ka ikehu hōʻailona RF a me ka microwave.He kaapuni hoʻokaʻawale ia nona ka lōʻihi uila he hana o ka lōʻihi kino a me ka wikiwiki o ka hoʻouna ʻana, he ʻokoʻa loa ia mai ka kaapuni alapine haʻahaʻa.

Hiki ke hoʻokaʻawale ʻia nā kaula coaxial Rf i nā uwea semi-rigid a me semi-flexible, nā kaula wili hiki ke hoʻololi ʻia, a me nā uwea huʻa kino.Pono e koho ʻia nā ʻano kaula like ʻole no nā noi like ʻole.Hoʻohana mau ʻia nā kaula semi-rigid a semi-flexible no ka hoʻopili ʻana i loko o nā mea hana;Ma ke kahua o ka hoʻāʻo ʻana a me ke ana ʻana, pono e hoʻohana ʻia nā kaula maʻalahi;Hoʻohana pinepine ʻia nā uwea foamed i nā ʻōnaehana hānai antenna base station.

uwea Semi-rigid
E like me ka inoa i hōʻike ʻia, ʻaʻole maʻalahi kēia ʻano kelepona i ke ʻano.Hana ʻia ka conductor waho me ka alumini a i ʻole ke keleawe keleawe.He liʻiliʻi loa ka leakage RF (emi ma lalo o -120dB) a he mea ʻole ke kamaʻilio keʻa i hana ʻia i loko o ka ʻōnaehana.

He kūpono loa ka ʻano intermodulation passive o kēia kelepona.Inā makemake ʻoe e kulou iā ia i kekahi ʻano, pono ʻoe i kahi mīkini hoʻoheheʻe kūikawā a i ʻole kahi mold manual e hana ai.ʻO ia ʻenehana hoʻoponopono pilikia ma ka hoʻihoʻi ʻana i ka hana paʻa loa, ke kaula semi-rigid me ka hoʻohana ʻana i nā mea polytetrafluoroethylene paʻa e like me ka mea hoʻopiha piha, ʻo kēia mea he mau hiʻohiʻona paʻa loa, ʻoi aku ma lalo o nā kūlana wela kiʻekiʻe, loaʻa ka paʻa maikaʻi loa.

ʻOi aku ke kumukūʻai o nā kaula Semi-rigid ma mua o nā kaula semi-flexible a hoʻohana nui ʻia i nā ʻōnaehana RF a me ka microwave.

uwea wili hikiwawe
ʻO ke kaula hikiwawe ke kelepona "hōʻoia".Ke hoʻohālikelike ʻia me nā kaula semi-rigid a me semi-flexible, ʻoi aku ka pipiʻi o ke kumukūʻai o nā kaula maʻalahi, no ka mea, ua hoʻolālā ʻia nā kaula maʻalahi e noʻonoʻo i nā mea ʻē aʻe.Pono e maʻalahi ke kulou ʻana i nā manawa he nui a mālama mau i ka hana, ʻo ia ke koi kumu ma ke ʻano he kaula hoʻāʻo.ʻO nā hōʻailona uila palupalu a maikaʻi he mau kū'ē'ē, akā alakaʻi pū i ke kumukūʻai o ke kumu nui.

ʻO ke koho ʻana i nā ʻāpana kelepona RF maʻalahi e noʻonoʻo i nā mea like ʻole i ka manawa like, a he kūʻē kekahi o kēia mau mea, no ka laʻana, ʻo ke kaula coaxial me ka conductor i loko hoʻokahi he haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa amplitude i ka wā e kulou ana ma mua o ke kaula coaxial multi-strand. , akā, ʻaʻole maikaʻi ka hana paʻa o ka pae e like me ka mea hope.No laila, ʻo ke koho ʻana i kahi ʻāpana kelepona, ma waho aʻe o ke alapine, ka lākiō hawewe kū, ka hoʻokomo ʻana a me nā mea ʻē aʻe, pono e noʻonoʻo i nā ʻano mechanical o ke kaula, ka ʻenehana hana a me nā koi noi, ʻo ia hoʻi, ʻo ke kumukūʻai he mau. mea kumu.
