Nūhou - Helical Duplexer No nā kamaʻilio VHF/UHF

Ke hoʻomau nei nā kaula alapine VHF/UHF i kahi hana nui i nā kamaʻilio kīwila a me nā ʻoihana.duplexer helicalHoʻohanohano ʻo ia i ka hana kānana pololei, ka paʻa paʻa a me ke kumukūʻai kiʻekiʻe, e lilo ia i koho kiʻekiʻe no nā ʻōnaehana lekiō, nā mea hana hou a me nā polokalamu kelepona.

ʻO ka pōmaikaʻi nui o kēiaduplexer kelepona helicalaia i loko o kāna hoʻolālā hoʻonohonoho helical, i hui pū ʻia me ka lōʻihi piha¼ λʻenehana resonance. Hiki i kēia hoʻolālā ke hoʻonohonoho i loko o ka ʻO 150MHz a me 380-450MHz mau alapine (frequency) me ka hoʻokō ʻana ma luna o 85 dB o ka hoʻokaʻawale ʻana—e kānana pono ana i nā clutter electromagnetic a me ka hoʻemi ʻana i ka pohō hoʻokomo i ka nui loa. Ma ke ʻano kūkulu, ʻo kaduplexer helicalhōʻike ʻia kahi hale alumini extruded compact, i hoʻokō ʻia e kahi chassis kila passivated a me nā ʻāpana Teflon-insulated. Ua uhi ʻia kona ʻaoʻao waho me ka vinyl ʻeleʻele pale i ka pala, e hōʻoiaʻiʻo ana i ka hana paʻa ʻoiai ma nā wahi waho a me nā ʻoihana ʻino.

1. Nā Mea Hana Hou Mana HaʻahaʻaMālama i kahi Voltage Standing Wave Ratio (VSWR) paʻa i ka wā o ka hana piha piha, e hōʻemi nui ana i ka nalowale ikehu. Kūpono loa no ka hoʻolaha ʻana me ka nānā ʻole ʻia ma nā wahi mauna, lalo o ka honua, a me nā wahi ʻē aʻe, kōkua ia i ka hoʻonui ʻana i ka uhi kamaʻilio.

2. Nā lekiō uila uila a me nā lekiō analogUhi i nā kāʻei alapine (frequency bands) VHF 150 MHz a me UHF 380–450 MHz, e hiki ai ke hoʻohui pono me nā lako hana nui me ka ʻole o ka pono no nā hoʻoponopono alapine hou aʻe. Hoʻopau loa ia i ka crosstalk i nā wahi electromagnetic paʻakikī, e hoʻolako ana i nā kamaʻilio hoʻouna ʻoihana a me nā pono hoʻohana lekiō amateur.

3. Kelepona Piha Nā Hāmeʻa DuplexMe kahi ʻano paʻa, ke kū'ē i ka haʻalulu, a me ka hiki ke hoʻololi i ka mahana, hiki iā ia ke hoʻoili maʻalahi a me ka synchronous i nā hōʻailona. He ʻāpana kūpono ia no nā hiʻohiʻona e like me ka hoʻopakele ulia pōpilikia a me nā hana kahua.

Ke hoʻohālikelike ʻia me ka nui o ka duplexer kuʻuna, loaʻa i kēia huahana kahi kaulike kūpono ma waena o ka hana a me ka pono, me nā pono koʻikoʻi i ka pono o ka ikehu a me ke kumukūʻai kūpono. He kūpono ia no ka hoʻolaha nui ʻana i nā papahana liʻiliʻi a me ka hoʻonui ʻana i nā lako ʻoihana, e hāʻawi ana i ke kākoʻo ikaika no nā kamaʻilio VHF/UHF hanauna hou.

E leka uila mai iā mākou no kahi ʻōlelo kūʻai! Hoʻohana nui ʻia i ka palekana o ka lehulehu, ka logistics a me ka halihali, ka automation ʻoihana, a me ka lekiō amateur, ua hilinaʻi nui ʻia kēia huahana e ka mākeke.
