He aha kakānana RF?

ʻO ka kānana alapine lekiō he ʻāpana koʻikoʻi o ka ʻenehana uila. Hoʻohana pū ʻia me ka mea hoʻokipa lekiō e kānana i nā ʻāpana alapine pono ʻole a loaʻa wale ke alapine kūpono. Hoʻolālā ʻia nā kānana RF e hana maʻalahi i ka pae alapine mai ka alapine waena a i nā alapine kiʻekiʻe loa (ʻo ia hoʻi megahertz a me gigahertz). Ma muli o kāna mau hiʻohiʻona hana, hoʻohana pinepine ʻia ia i nā lekiō, ke kelepona uila, televise a me nā mea hana ʻē aʻe.

ʻO ka maʻamau, ʻo ka hapa nui o nā kānana RF i hui pū ʻia me nā resonator i hui pū ʻia, a hiki i kā lākou mau mea maikaʻi ke hoʻoholo i ka pae kānana ma RF. Ma muli o ka noi a me ka nui o nā lako uila, he nui nā ʻano kānana, ʻo ia hoʻi ka kānana cavity, kānana mokulele, kānana electroacoustic, kānana dielectric, kānana coaxial (kūʻokoʻa i ke kaula coaxial), etc.

Nā ʻano kumu o ke kānana lekiō

ʻO ka kānana RF kahi kaapuni kūikawā e hiki ai i nā hōʻailona kūpono ke hele ma ke kāpae ʻana i nā hōʻailona makemake ʻole. I ka ʻōlelo o ka topology kānana, ʻehā mau ʻano kānana RF maʻamau, ʻo ia hoʻi, kānana pass kiʻekiʻe, kānana pass haʻahaʻa, kānana band pass a me ka kānana band stop.

Kānana Ala Haʻahaʻa:

E like me ka inoa e hōʻike nei, ʻo kahi kānana haʻahaʻa haʻahaʻa he kānana e ʻae wale i nā alapine haʻahaʻa e hele a hoʻemi i nā alapine hōʻailona ʻē aʻe i ka manawa like. Ke hele ka hōʻailona ma kahi bandpass, hoʻoholo ʻia kona hōʻemi pinepine ʻana e nā kumu he nui, e like me ka topology kānana, ka hoʻonohonoho a me ka maikaʻi o nā mea. Eia kekahi, hoʻoholo ka topology kānana i ka wikiwiki o ka hoʻololi o ka kānana mai ka passband e hoʻokō i kāna hoʻopau hope.

Hiki mai nā kānana ha'aha'a ma nā 'ano like 'ole. ʻO ka noi nui o ka kānana ke kāohi i ka harmonic o RF amplifier. He mea koʻikoʻi kēia hiʻohiʻona no ka mea kōkua ia i ka pale ʻana i ke keʻakeʻa pono ʻole mai nā hui hoʻouna like ʻole. ʻO ka mea nui, hoʻohana ʻia nā kānana haʻahaʻa haʻahaʻa no nā noi leo a kānana i ka walaʻau mai kekahi kaapuni waho. Ma hope o ka kānana ʻana i ka hōʻailona hōʻailona kiʻekiʻe, loaʻa kahi ʻano maʻemaʻe o ke alapine i loaʻa.

Kānana Holo Kiʻekiʻe:

ʻOkoʻa i ka kānana ala haʻahaʻa, hiki i ka kānana ala kiʻekiʻe ke hele i nā hōʻailona alapine kiʻekiʻe wale nō. ʻO ka ʻoiaʻiʻo, ʻo ka kānana ala kiʻekiʻe a me ka kānana ala haʻahaʻa he hoʻohui nui, no ka mea hiki ke hoʻohana pū ʻia nā kānana ʻelua e hana i kahi kānana band-pass. ʻO ka hoʻolālā o ka kānana hele kiʻekiʻe he pololei a hoʻemi i ke alapine ma lalo o ka paepae paepae.

ʻO ka maʻamau, hoʻohana ʻia nā kānana kiʻekiʻe i nā ʻōnaehana leo, kahi e kānana ʻia ai nā alapine haʻahaʻa. Eia kekahi, hoʻohana ʻia e wehe i nā ʻōlelo liʻiliʻi a me nā bass i nā manawa he nui; Hoʻokumu ponoʻia kēia mau kānana i loko o nā mea'ōlelo. Eia nō naʻe, inā pili kekahi papahana DIY, hiki ke hoʻopili maʻalahi ka kānana kiʻekiʻe i ka ʻōnaehana.

Nā kānana Band Pass:

ʻO kahi kānana band-pass kahi kaapuni e hiki ai i nā hōʻailona mai ʻelua mau alapine like ʻole ke hele a hoʻemi i nā hōʻailona ʻaʻole i loko o kāna ākea ʻae. ʻO ka hapa nui o nā kānana band-pass e hilinaʻi i kekahi kumu mana waho a hoʻohana i nā mea hana, ʻo ia hoʻi nā kaapuni i hoʻohui ʻia a me nā transistors. Kapa ʻia kēia ʻano kānana i ke kānana band-pass hana. Ma ka ʻaoʻao ʻē aʻe, ʻaʻole hoʻohana kekahi mau kānana band-pass i ka mana o waho a hilinaʻi nui i nā ʻāpana passive, ʻo ia hoʻi nā inductors a me nā capacitors. Kapa ʻia kēia mau kānana i nā kānana passive band-pass.

Hoʻohana mau ʻia nā kānana Bandpass i nā mea hoʻokipa uila a me nā mea hoʻouna. ʻO kāna hana nui i ka transmitter ka palena o ka bandwidth o ka hōʻailona hoʻopuka i ka liʻiliʻi, i hiki ke hoʻouna ʻia ka ʻikepili i koi ʻia i ka wikiwiki a me ke ʻano. Ke komo ka mea hoʻokipa, ʻae ka kānana band-pass i ka decoding a i ʻole ka lohe ʻana i ka helu i koi ʻia o nā alapine, ʻoiai e ʻoki ana i nā hōʻailona ʻē aʻe mai nā alapine makemake ʻole.

Ma kahi huaʻōlelo, ke hoʻolālā ʻia kahi kānana band-pass, hiki iā ia ke hoʻonui maʻalahi i ka maikaʻi o ka hōʻailona a hoʻemi i ka hoʻokūkū a i ʻole ke keakea ʻana ma waena o nā hōʻailona.

Hōʻole ka bana:

I kekahi manawa i kapa ʻia ʻo band stop filter, band stop filter kahi kānana e hiki ai i ka hapa nui o nā alapine ke hele me ka loli ʻole. Eia naʻe, hoʻemi ia i nā alapine ma lalo o kahi kikoʻī kikoʻī. He kū'ē loa kāna hana i ka kānana band-pass. ʻO ka mea maʻamau, ʻo kāna hana ka hoʻohele ʻana i ke alapine mai ka ʻole a i ka ʻoki mua ʻana o ke alapine. Ma waena, e hala i nā alapine a pau ma luna o ka helu ʻoki ʻelua o ke alapine. Eia naʻe, hōʻole a poloka ia i nā alapine ʻē aʻe ma waena o kēia mau kiko ʻelua.

Ma kahi huaʻōlelo, ʻo kahi kānana kahi mea e hiki ai i nā hōʻailona ke hele ma ke kōkua o ka passband. I nā huaʻōlelo ʻē aʻe, ʻo ka stopband i loko o ka kānana kahi i hōʻole ʻia ai kekahi mau alapine e kekahi kānana. ʻO ke ala kiʻekiʻe, ka haʻahaʻa a i ʻole ka band pass, ʻo ka kānana kūpono he kānana me ka pohō ʻole o ka pā hele. Eia naʻe, ʻoiaʻiʻo, ʻaʻohe kānana kūpono no ka loaʻa ʻana o ka bandpass i ka nalowale alapine a ʻaʻole hiki ke hoʻokō i ka hoʻopau ʻole ʻana i ka wā e hiki ai ka stopband.

No ke aha he mea koʻikoʻi nā kānana Radio Frequency?

Hoʻohana ʻia nā kānana RF e hoʻokaʻawale i nā alapine hōʻailona, ​​​​akā he aha ka mea nui? I ka pōkole, hiki i nā kānana RF ke kānana i nā leo e pili ana i ka maikaʻi a i ʻole ka hana o kekahi ʻōnaehana kamaʻilio a i ʻole e hōʻemi i ka hoʻopili ʻana o nā hōʻailona waho. ʻO ka nele o ka kānana RF kūpono e hōʻino paha i ka hoʻouna ʻana i ka alapine hōʻailona, ​​​​a i ka hopena hiki ke hōʻino i ke kaʻina kamaʻilio.

No laila, hoʻokani koʻikoʻi nā kānana RF i nā ʻōnaehana kamaʻilio kelepona (ʻo ia hoʻi ka satellite, radar, nā ʻōnaehana kelepona kelepona, a me nā mea ʻē aʻe). I ka hiki ʻana mai i ka hana o nā kaʻa mokulele unmanned (UAS), ʻike ʻia ka mea nui o nā kānana RF. ʻO ka nele o ka ʻōnaehana kānana kūpono e hoʻopilikia iā UAS ma nā ʻano he nui, e like me:

Hiki ke hoʻemi ʻia ka laulā kamaʻilio i ka hoʻopilikia ʻia e nā kumu kūlohelohe o waho. Eia kekahi, ʻo ka loaʻa ʻana o ka nui o nā hōʻailona RF i ka lewa hiki ke hōʻeha nui i ka ʻōnaehana kamaʻilio UAV. Loaʻa nā hōʻailona hōʻino mai nā paepae ʻē aʻe akā ʻaʻole i kaupalena ʻia i:; ʻO ka hana hōʻailona Wi Fi ikaika a me nā ʻōnaehana kamaʻilio ʻē aʻe e hana ana i loko o ka UAS.

ʻO nā keʻakeʻa mai nā ʻōnaehana kamaʻilio ʻē aʻe e hoʻopau i ke kaila kamaʻilio UAS, a laila e hōʻemi a kaupalena ʻia ka laulā kamaʻilio o ia ʻōnaehana.

E hoʻopilikia pū kekahi i ka hōʻailona GPS o ka UAS; Hoʻonui kēia i ka hiki ʻana o nā hewa i ka nānā ʻana GPS. I ka hihia ʻino loa, hiki i kēia ke hopena i ka nalowale piha o ka loaʻa ʻana o ka hōʻailona GPS.

Me ka kānana RF kūpono, hiki ke hoʻopau maʻalahi ka hoʻopili ʻana i waho a me ka hōʻailona hōʻailona i hana ʻia e nā ʻōnaehana kamaʻilio pili. Mālama kēia i ka maikaʻi o ka alapine hōʻailona makemake ʻoiai e kānana maʻalahi i nā alapine hōʻailona makemake ʻole.

Eia kekahi, hana koʻikoʻi nā kānana RF i ke kaiapuni kelepona. I ka wā e pili ana i nā kelepona paʻalima, pono lākou i kahi helu o nā alapine e hana pono. Ma muli o ka loaʻa ʻole o nā kānana RF kūpono, ʻaʻole e hui pū nā ʻano alapine like ʻole i ka manawa like, ʻo ia hoʻi, e hōʻole ʻia kekahi mau kaha alapine, ʻo ia hoʻi, Global Navigation Satellite System (GNSS), palekana lehulehu, Wi Fi, a pēlā aku.

Ma keʻano laulā, māmā nā kānana i ke kaumaha a kōkua i ka hoʻomaikaʻi ʻana i ka hana o ke alapine hōʻailona. Inā ʻaʻole hāʻawi ka kānana RF i ka hana i makemake ʻia, a laila hiki iā ʻoe ke ʻimi i nā ʻano koho ʻē aʻe, ʻo kekahi o ia ka hoʻohui ʻana i nā amplifier i kāu hoʻolālā. Mai ka hoʻonui ʻana i ka grid i kekahi mea hoʻonui mana RF ʻē aʻe, hiki iā ʻoe ke hoʻololi i ke alapine hōʻailona haʻahaʻa i ke alapine hōʻailona kiʻekiʻe; No ka hoʻomaikaʻi ʻana i ka hana holoʻokoʻa o ka hoʻolālā RF.

ʻO Si Chuan Keenlion Microwave kahi koho nui ma nā ʻāpana haiki a me ka laulā ākea, e uhi ana i nā alapine mai 0.5 a 50 GHz. Hoʻolālā ʻia lākou e lawelawe mai ka 10 a 30 watts mana hoʻokomo i loko o kahi ʻōnaehana hoʻouna 50-ohm. Hoʻohana ʻia nā hoʻolālā Microstrip a i ʻole stripline, a hoʻopaʻa ʻia no ka hana maikaʻi loa.

Hiki iā mākou ke hana i ka RF Filter e like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻoponopono e hāʻawi i nā kikoʻī āu e pono ai.
