I loko o nā ʻōnaehana kamaʻilio uea ʻole o kēia wā, ʻo nā duplexers, triplexers a me quadplexers nā ʻāpana passive koʻikoʻi no ka hoʻokō ʻana i ka hoʻoili hōʻailona multi-band. Hoʻohui a hoʻokaʻawale paha lākou i nā hōʻailona mai nā ʻāpana alapine he nui, e ʻae ana i nā mea hana e hoʻouna a loaʻa i nā alapine he nui i ka manawa like i ka wā e kaʻana like ana i nā antenna. ʻOiai nā ʻokoʻa o nā inoa a me nā hale, ua like ko lākou mau kumu kumu, me ka ʻokoʻa nui ʻo ka helu a me ka paʻakikī o nā kaha alapine i hana ʻia.
Duplexer
ʻO ka duplexer he ʻelua kānana e kaʻana like i kahi awa maʻamau (maʻamau he antenna) a hoʻohana ʻia e hoʻokō i nā hana o ka transmit (Tx) a loaʻa (Rx) ma ka mea like. Hoʻohana nui ʻia ia i nā ʻōnaehana frequency division duplex (FDD) e pale ai i ka hoʻopili like ʻana ma o ka hoʻokaʻawale ʻana i ka transmit a loaʻa nā hōʻailona. Pono nā Duplexers i kahi kiʻekiʻe o ka noho kaʻawale, ʻoi aku ma mua o 55 dB, i mea e hōʻoia ai ʻaʻole pili ka hōʻailona i hoʻouna ʻia i ka naʻau o ka mea hoʻokipa.
Tripplexer
Loaʻa i kahi tripplexer ʻekolu kānana e kaʻana like i kahi awa maʻamau. Hāʻawi ia i kahi mea hana e hana i nā hōʻailona mai ʻekolu mau ala alapine like ʻole i ka manawa like a hoʻohana pinepine ʻia i nā ʻōnaehana kamaʻilio e pono ai ke kākoʻo i nā alapine he nui i ka manawa like. Pono ka hoʻolālā ʻana o ka triplexer e hōʻoia ʻaʻole e hoʻouka ka passband o kēlā me kēia kānana i nā kānana ʻē aʻe a hāʻawi i kahi kaʻawale kūpono e pale ai i ka hoʻopili like ʻana ma waena o nā kaha alapine.
Pākuʻi ʻehā
Loaʻa i kahi quadplexer ʻehā kānana e kaʻana like i kahi awa maʻamau. Hāʻawi ia i ka hāmeʻa e hana i nā hōʻailona mai ʻehā mau ʻāpana alapine like ʻole i ka manawa like a kūpono i nā ʻōnaehana kamaʻilio paʻakikī e koi ana i ka pono spectral kiʻekiʻe, e like me ka ʻenehana hoʻohui lawe. He kiʻekiʻe ka paʻakikī o ka hoʻolālā ʻana o ka quadplexer a pono e hoʻokō i nā koi cross-isolation koʻikoʻi e hōʻoia i ka hoʻopili ʻole ʻana o nā hōʻailona ma waena o nā kaha alapine.
Nā ʻokoʻa nui
Ka helu o nā kaha alapine: Hoʻoponopono nā Duplexers i ʻelua mau kaha alapine, hana ʻekolu mau kaha alapine ʻekolu, a ʻo nā pahu ʻehā ʻehā.
ʻO ka paʻakikī o ka hoʻolālā: Ke piʻi nei ka nui o nā kaha alapine, ʻoi aku ka paʻakikī o ka hoʻolālā a me nā koi kaʻawale.
Nā hiʻohiʻona noiʻi: Hoʻohana pinepine ʻia nā Duplexers i nā ʻōnaehana FDD maʻamau, ʻoiai hoʻohana ʻia nā triplexers a me nā quadplexers i nā ʻōnaehana kamaʻilio holomua e pono e kākoʻo i nā ʻāpana alapine he nui i ka manawa like.
ʻO ka hoʻomaopopo ʻana i nā ʻano hana a me nā ʻokoʻa o nā duplexers, triplexers, a me quadplexers he mea koʻikoʻi i ka hoʻolālā ʻana a me ka hoʻonui ʻana i nā ʻōnaehana kamaʻilio uila. ʻO ke koho ʻana i ke ʻano multiplexer kūpono hiki ke hoʻomaikaʻi maikaʻi i ka hoʻohana ʻana o ka spectrum a me ka maikaʻi kamaʻilio.
