I ka makahiki 2020, i ka hui pū ʻana me Huawei ma Kina, e komo mākou i ke kūkulu ʻana i nā kaukani o nā kikowaena pūnaewele kelepona ʻole i ka huina, a ma waena o mākou e hāʻawi i nā microstrip power dividers me nā alapine o 0.5 / 6g a me 1-50g e like me ke kākoʻo lako.
ʻOi aku ka nui o ka uhi ʻana o nā mea hoʻokele pūnaewele kelepona i ka makahiki 2021, a ʻo ka nui o ka helu e manaʻo ʻia e ʻoi aku ma mua o ʻumi kaukani mau mea hana.
ʻO nā kaha alapine kūpono no nā kamaʻilio ukali
Manawa: 2021-10-28
Ua wehewehe ʻo ITU i nā kaha alapine, i hoʻohana ʻia no nā kamaʻilio ukali.
UHF (Ultra High Frequency) a i ʻole decimeter wave frequency band, ʻo 300MHz-3GHz ka laulā alapine.
Pili kēia pūʻulu alapine me IEEE UHF (300MHz-1GHz), L (1-2GHz), a me S (2-4GHz).
ʻO nā hawewe lekiō alapine UHF kokoke i ka hoʻolaha ʻana o ka ʻike, maʻalahi ke kāohi ʻia e nā mauna a me nā hale, a me nā mea ʻē aʻe, a ʻoi aku ka nui o ka attenuation o loko.
SHF (Super High Frequency) a i ʻole centimeter wave frequency band, ʻo ka laina alapine he 3-30GHz.
Pili kēia pūʻulu alapine me IEEE S (2-4GHz), C (4-8GHz), Ku (12-18GHz), K (18-27GHz) a me Ka (26.5-40GHz).
He 1cm-1dm ka nalu decimeter, a ua kokoke ko lakou ano hoolaha i na nalu malamalama.
EHF (Extremely High Frequency) a i ʻole millimeter wave frequency band, ʻo 30-300GHz ka laulā alapine.
Pili kēia pūʻulu alapine i ka IEEE's Ka (26.5-40GHz), V (40-75GHz) a me nā ala alapine ʻē aʻe.
Ua hoʻomaka nā ʻāina i kūkulu ʻia i ka hoʻolālā e hoʻohana i nā kaha alapine 50/40GHz Q/V ma nā ʻīpuka o ka lawelawe ʻoihana paʻa-satellite kiʻekiʻe (HDFSS) i ka wā e paʻa ana nā kumuwaiwai Ka-band.
Hiki iā mākou ke hana i nā ʻāpana passive rf e like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻoponopono e hāʻawi i nā kikoʻī āu e pono ai.
