Aia nā ʻāpana microwavenā mea hana microwave, ʻike ʻia hoʻi he mau mea RF, e like me nā kānana, mixers, etc.Loaʻa pū kekahi i nā ʻāpana multifunctional i haku ʻia me nā kaapuni microwave a me nā mea hana microwave discrete, e like me nā ʻāpana tr, nā ʻāpana hoʻololi alapine i luna a i lalo, etc;Aia pū kekahi mau subsystems, e like me nā mea hoʻokipa.
Hoʻohana nui ʻia nā ʻāpana Microwave i ka pūʻali koa i ka radar, kamaʻilio, nā countermeasures uila a me nā mea ʻike ʻike pale aupuni ʻē aʻe, a me ka waiwai o nā ʻāpana microwave, ʻo ia hoʻi, ka ʻaoʻao o ka lekiō. o ka oihana koa;Eia kekahi, ma ke kahua kīwila, hoʻohana nui ʻia i lokokamaʻilio ʻole, kaʻa kaʻamillimeter wave radar,a me nā mea ʻē aʻe, aia i kahi subfield me ka koi ikaika no ka mana kūʻokoʻa ma waena a me luna o nā ʻenehana kumu a me nā ʻenehana o Kina.He wahi nui loa no ka hoʻohui kīwila pūʻali koa, no laila e nui aʻe nā manawa hoʻolimalima i nā ʻāpana microwave.
Hoʻohana ʻia nā ʻāpana microwave e ʻike i ke alapine, ka mana, ka pae a me nā hoʻololi ʻē aʻe o nā hōʻailona microwave.Ma waena o lākou, ua like nā manaʻo o nā hōʻailona microwave a me RF, ʻo ia hoʻi, nā hōʻailona analog me nā alapine kiʻekiʻe, maʻamau mai ka ʻumi megahertz a hiki i nā haneli gigahertz a terahertz;Hoʻokumu ʻia nā ʻāpana microwave me nā kaʻa microwave a me kekahi mau mea hana microwave discrete.ʻO ke kuhikuhi hoʻomohala ʻenehana ʻo ka miniaturization a me ke kumu kūʻai haʻahaʻa.ʻO nā ala ʻenehana e ʻike ai iā lākou e komo pū me Hmic a me MMIC.Hoʻolālā ʻo MMIC i nā ʻāpana microwave ma kahi chip semiconductor.ʻO ka degere hoʻohui ʻia ʻo 2 ~ 3 mau kauoha o ka nui ma mua o Hmic.ʻO ka maʻamau, hiki i kahi MMIC ke hoʻomaopopo i hoʻokahi hana.I ka wā e hiki mai ana, he hoʻohui multi-functional.ʻO ka hope, e ʻike ʻia nā hana pae ʻōnaehana ma hoʻokahi chip, lilo ia i RF SOC kaulana;Hiki ke manaʻo ʻia ʻo Hmic i ka hoʻohui lua o MMIC.Hoʻokomo nui ʻia ka Hmic i ke kaapuni hoʻohui kiʻi ʻoniʻoni mānoanoa, ka pōʻai hoʻohui kiʻi ʻoniʻoni ʻoniʻoni a me ka ʻōnaehana pae hoʻopili sip.ʻO ka pōʻaiapuni hoʻohui kiʻi mānoanoa he kaʻina hana microwave maʻamau, nona nā mea maikaʻi o ke kumu kūʻai haʻahaʻa, pōkole pōkole a me ka hoʻolālā maʻalahi.ʻO ke kaʻina hana hoʻopihapiha 3D e pili ana i ka LTCC hiki ke hoʻomaopopo hou i ka miniaturization o nā ʻāpana microwave, a ke piʻi mālie nei kāna noi ma ka kahua kaua.Ma ke kahua kaua, hiki ke hana ʻia kekahi mau ʻāpana me ka nui o ka hoʻohana ʻana i hoʻokahi pahu.No ka laʻana, he nui loa ka hoʻohana ʻana i ka mana hoʻonui hope loa i ka module TR o phased array radar, a he mea pono ke hoʻolilo iā ia i hoʻokahi chip;No ka laʻana, ʻaʻole kūpono nā huahana liʻiliʻi liʻiliʻi e hana ʻia i loko o nā ʻāpana hoʻokahi, akā ʻo ka nui o nā hybrid integrated circuits.
Ma ka mākeke koa, ʻoi aku ka nui o ka waiwai o nā ʻāpana microwave ma mua o 60% ma nā kahua o ka radar, kamaʻilio a me nā countermeasures uila.Ua manaʻo mākou i ka mākeke o nā ʻāpana microwave ma ke kahua o ka radar a me nā countermeasures uila.Ma ke kahua o ka radar, ua manaʻo nui mākou i ka waiwai hoʻopuka radar o nā keʻena noiʻi radar nui o Kina, me 14 a me 38 Institute of CETC, 23, 25 a me 35 Institutes of Aerospace Science a me ka ʻoihana, 704 a me 802 Institutes of Aerospace Science a me ka ʻenehana. 607 Institutes of AVIC, etc, Manaʻo mākou he 33billion ka mākeke ma 2018, a ʻo ka mākeke no nā ʻāpana microwave e hiki i 20billion;ʻO ka 29 Institute of CETC, 8511 Institutes of Aerospace Science a me ka ʻoihana a me 723 Institutes of CSIC e noʻonoʻo nui ʻia no nā countermeasures uila.ʻO ka mākeke holoʻokoʻa o nā mea hana countermeasures uila ma kahi o 8billion, nona ka waiwai o nā ʻāpana microwave he 5billion.ʻAʻole mākou i noʻonoʻo i ka ʻoihana kamaʻilio no ka manawa no ka mea ʻoi loa ka ʻāpana o ka mākeke o kēia ʻoihana.Ma hope, e hoʻomau mākou i ka noiʻi hohonu a me ka hoʻohui.ʻO ka mākeke o nā ʻāpana microwave i ka radar a me nā countermeasures uila wale nō i hiki i 25billion.
ʻO ka mākeke kīwila ka mea nuikamaʻilio ʻolea me ka radar nalu millimeter kaʻa.Ma ke kahua o ke kamaʻilio kelepona, ʻelua ʻāpana o ka mākeke: kelepona paʻa a me ke kahua kahua.ʻO ka RRU ma ke kahua kahua ka nui o nā ʻāpana microwave e like me ka module, transceiver module, power amplifier a me kāna module filter.Hōʻike nā ʻāpana Microwave i ka piʻi nui ʻana o ke kahua kumu.Ma nā kikowaena pūnaewele 2G, ʻo ka waiwai o nā polokalamu RF e pili ana i ka 4% o ka waiwai o ka waihona kumu holoʻokoʻa.Me ka hoʻomohala ʻana o ka base station e pili ana i ka miniaturization, ua piʻi mālie nā polokalamu RF i nā ʻenehana 3G a me 4G i 6% ~ 8%, a hiki i ka hapa o kekahi mau kahua kahua ke hiki i 9% ~ 10%.E hoʻomaikaʻi hou ʻia ka ʻāpana waiwai o nā mea RF i ka wā 5g.I loko o ka ʻōnaehana kamaʻilio kelepona paʻa, ʻo RF mua-hope kekahi o nā mea nui.ʻO nā mea hana RF i loko o nā pahu kelepona ʻo ia ka mea nui i ka mana amplifier, duplexer, RF switch, kānana, haʻahaʻa haʻahaʻa haʻahaʻa, a me nā mea ʻē aʻe.ʻO ke kumukūʻai maʻamau i ka wā 4G ma kahi o $10, a ua manaʻo ʻia ʻo 5g ma mua o $50.Manaʻo ʻia ka mākeke nalu millimeter wave radar e hōʻea i 5billion US kālā ma 2020, kahi o ka RF front-end ʻāpana he 40% ~ 50%.
ʻO nā ʻāpana microwave pūʻali koa a me nā ʻāpana microwave kīwila i hui pū ʻia ma ke kumu, akā i ka wā e pili ana i nā noi kikoʻī, ʻokoʻa nā koi no nā ʻāpana microwave, e hopena i ka hoʻokaʻawale ʻana o nā pūʻali koa a me nā ʻāpana kīwila.No ka laʻana, koi maʻamau nā huahana koa i ka mana hoʻokuʻu kiʻekiʻe e ʻike i nā pahuhopu mamao loa, ʻo ia ka hoʻomaka o kā lākou hoʻolālā ʻana, ʻoiai nā huahana kīwila e nānā nui aku i ka pono;Eia kekahi, ʻokoʻa ka alapine.I mea e pale aku ai i ka hoʻopilikia ʻana, ke piʻi aʻe nei ka bandwidth hana o ka pūʻali koa a ʻoi aku ka kiʻekiʻe, ʻoiai ʻo ke kīwila ma ke ʻano maʻamau.Eia kekahi, ʻoi aku ka nui o nā huahana kīwila i ke kumukūʻai, ʻoiai ʻaʻole pili nā huahana koa i ke kumukūʻai.
Me ka hoʻomohala ʻana o ka ʻenehana i ka wā e hiki mai ana, e ʻoi aku ka nui o nā mea like ma waena o ka hoʻohana pūʻali koa a me ka hoʻohana kīwila, a e hui pū nā koi no ka pinepine, ka mana a me ke kumu kūʻai haʻahaʻa.E lawe i ka hui kaulana ʻAmelika qorvo i laʻana.ʻAʻole wale ia e lawelawe ma ke ʻano he PA o ke kahua kahua, akā hāʻawi pū kekahi i ka Power Amplifier MMIC no ka radar pūʻali koa, i hoʻohana ʻia ma Shipborne, airborne a me nā ʻōnaehana hoʻokele ʻāina, a me ka kamaʻilio a me nā ʻōnaehana kaua uila.I ka wā e hiki mai ana, e hōʻike pū ana ʻo Kina i kahi kūlana o ka hoʻomohala hoʻohui ʻana i nā pūʻali koa, a aia kahi manawa kūpono no ka pūʻali koa i ka hoʻohuli kīwila.
