Nā kānana RF: Nā ʻāpana koʻikoʻi koʻikoʻi o nā hāmeʻa kamaʻilio uila

Nā kānana RF, ma ke ʻano he ʻāpana koʻikoʻi o nā ʻōnaehana kamaʻilio uila, e hoʻokō i ka loiloi hōʻailona a hoʻomaikaʻi i ka maikaʻi o ka hoʻouna ʻana ma ke kānana koho ʻana i nā hōʻailona alapine. I kēia ao pili loa, ke kuleana oNā kānana RFʻaʻole hiki ke mālama ʻia.

Nā hana nui a me nā hiʻohiʻona oNā kānana RF

Nā kānana RFhiki ke hoʻomaikaʻi maikaʻi i ka maikaʻi o nā ʻōnaehana kamaʻilio ma ka hōʻole ʻana i nā hōʻailona makemake ʻole a me ka ʻae ʻana i nā hōʻailona frequency target e hala. Hoʻohana nui ʻia lākou i nā kamaʻilio kelepona, kamaʻilio satellite, radar, a me nā polokalamu Pūnaewele o nā Mea (IoT).

Kiʻekiʻe-hanaNā kānana RFpono e loaʻa nā ʻano penei:

Haʻahaʻa hoʻokomo poho: hōʻoia i ka liʻiliʻi loa attenuation hōʻailona i loko o ka passband.

ʻO ka hoʻokaʻawale kiʻekiʻe a me ka attenuation stopband: hoʻopaʻa pono i nā hōʻailona non-target a hoʻemi i ka hoʻopili.

Waiwai Q kiʻekiʻe: hoʻomaikaʻi i ka koho a me ka pololei o ka kānana.

Hana maikaʻi loa passive intermodulation (PIM): hōʻemi i ka intermodulation intermodulation hōʻailona a hoʻomaikaʻi i ka paʻa o ka ʻōnaehana.

Hoʻolālā liʻiliʻi: hoʻololi i nā pono o nā mea hana hou no nā hale paʻa ʻoiai e hōʻoiaʻiʻo ana i ka hiki ke hoʻokele mana.

Nā ʻano oNā kānana RF

Ma muli o nā mea hana a me nā kaʻina hana,Nā kānana RFhiki ke maheleia i kekahi mau ano:
Nā kānana lua
Nā kānana dielectric
Nā kānana Coaxial
Nā kānana Planar
Nā kānana Electroacoustic
Loaʻa i kēlā me kēia kānana nā pōmaikaʻi kūʻokoʻa i ka hoʻolālā, hana a me nā hiʻohiʻona noi, a hiki ke hoʻokō i nā pono o nā ʻōnaehana kamaʻilio kelepona ʻole.

Nā Kūlana Makeke

Me ka hoʻolaha nui ʻana o nā pūnaewele 5G a me ka hoʻonui ʻana i nā noi i ka band hawewe millimeter, koi ka mākeke no ke alapine kiʻekiʻe a me ka hana kiʻekiʻe.Nā kānana RFke ulu mau nei. Eia kekahi, ʻo ka piʻi ʻana o nā mea IoT ua hāʻawi pū i nā mea hou aʻe no ka ʻenehana ʻenehana o nā kānana RF.

Ka mea nui oNā kānana RF

I nā ʻōnaehana kelepona ʻole, ke kuleana oNā kānana RFʻaʻole i kaupalena ʻia i ka hele ʻana i nā hōʻailona alapine kikoʻī, akā pū kekahi me ka pale ʻana i nā alapine interfering a me ka maikaʻi o ka hōʻailona. Pono nā lako uila o kēia wā i nā kānana i haku ʻia me nā resonator, nā alakaʻi nalu a i ʻole nā ​​mea passive e kākoʻo i kā lākou mau hana kamaʻilio. Ke hilinaʻi nei kēlā me kēia mea hanaNā kānana RFe hōʻoia i ka hoʻouna kūpono a me ka hilinaʻi o nā hōʻailona.

Hōʻuluʻulu manaʻo

Ma ke ʻano he ʻāpana kumu o nā ʻōnaehana kamaʻilio uila,Nā kānana RFpāʻani i kahi kuleana nui i ka hana pono o nā mea hana. Mai nā smartphones i nā ʻōnaehana radar a i nā terminal IoT, nā wahi noi oNā kānana RFe hoonui mau ana. Me ka holomua o ka ʻenehana a me ka piʻi ʻana o ka noi no nā kamaʻilio uila,Nā kānana RFe pāʻani i kahi kūlana koʻikoʻi i ka mākeke e hiki mai ana.
Inā ʻoe e ʻimi nei i ke kūlana kiʻekiʻekānana RFnā hāʻina, hiki iā mākou ke hāʻawi iā ʻoe i nā ʻano koho maʻamau a i hoʻonohonoho ʻia paha, a e alakaʻi i kāu mau huahana me kahi lawelawe ʻekolu makahiki! E ʻoluʻolu e kelepona mai iā mākou no ka ʻike hou aku.
