E PILI I KĒIA MANAWA

ʻO ka mea hana mana microwave paʻa-mokuʻāina he mea uila e hoʻohana ana i nā mea semiconductor e like me Gunn diodes, IMPATT diodes, FET transistors, HEMT transistors, a me nā mea ʻē aʻe e hana i nā nalu electromagnetic alapine microwave (e pili pinepine ana i 300MHz ~ 300GHz).

He ʻokoʻa loa ia mai nā kumu microwave "electric vacuum devices" kuʻuna e like me nā magnetrons, nā paipu nalu huakaʻi, a me nā klystrons. Hilinaʻi nā mea kuʻuna i ka neʻe ʻana o nā electrons manuahi i loko o ka vacuum e hana i nā microwaves, ʻoiai ʻo nā mea hana mana microwave solid-state e hilinaʻi piha i nā ʻano o nā mea paʻa semiconductor, e hana ana i nā oscillations ma o ka neʻe ʻana a me ka pae ikehu o nā electrons i loko o ka semiconductor lattice structure.

Nā ʻano:

1. Ka liʻiliʻi a me ke kaumaha māmā: ʻO ke kikowaena he ʻāpana semiconductor, ʻaʻole pono nā ʻōmole vacuum a i ʻole nā lako mana kiʻekiʻe-voltage, e hoʻolilo ana i ka hāmeʻa holoʻokoʻa i mea liʻiliʻi loa a maʻalahi hoʻi e hoʻohui i nā ʻōnaehana uila hou.
2. Haʻahaʻa ka uila hana a me ka palekana kiʻekiʻe: ʻO ka maʻamau, he mau volts a he ʻumi volts wale nō o ka mana uila haʻahaʻa DC e pono ai, ʻoiai ʻo nā mea hana vacuum uila e koi pinepine i nā tausani volts o ka uila kiʻekiʻe. ʻO kēia ka mea e palekana ai a maʻalahi ka hoʻolālā mana.
3. Ola lōʻihi a me ka hilinaʻi kiʻekiʻe: Me ka ʻole o nā mea hoʻopau e like me nā filament cathode, ua lōʻihi loa ke ola kumumanaʻo o nā mea semiconductor, hiki i nā ʻumi a i ʻole nā haneli haneli mau hola, ʻoi aku ka nui ma mua o nā paipu microwave kuʻuna.
4. Ka maʻemaʻe o ka spectrum a me ke kūpaʻa alapine (frequency): ʻOi aku hoʻi no nā kumu solid-state e hoʻohana ana i ka ʻenehana phase-locked loop (PLL), hiki iā lākou ke hana i nā hōʻailona microwave maʻemaʻe loa a paʻa loa me ka walaʻau haʻahaʻa.
5. Ka wikiwiki o ka hoʻonohonoho wikiwiki ʻana a me ka mana maʻalahi: Hiki ke hoʻololi koke ʻia ke alapine hoʻopuka, ka pae, a me ka amplitude ma o ka voltage (voltage controlled oscillator VCO) a i ʻole nā hōʻailona kikohoʻe, e maʻalahi ai ka hoʻokō ʻana i ka modulation paʻakikī a me ka agility.
6. Kū'ē maikaʻi i ka haʻalulu a me ka haʻalulu: Me kahi ʻano paʻa, ʻaʻohe pūpū aniani palupalu a i ʻole nā filaments, e ʻoi aku ka maʻalahi i nā ʻano mechanical ʻino.

Noi:

1. ʻO ke kumu radar hou: Hoʻohana nui ʻia i ka radar nalu millimeter automotive, ka radar array phased koa, a me nā mea ʻē aʻe, e hoʻokō i ka ʻike pololei a me ka scan kukuna wikiwiki.
2. Ke kahua kamaʻilio uea ʻole: He ʻāpana koʻikoʻi ia o nā kikowaena kahua 5G/6G, ke kamaʻilio ukali, a me nā lako hoʻoili microwave, kuleana no ka hoʻoulu ʻana i nā hōʻailona lawe alapine kiʻekiʻe.
3. Hoʻāʻo pololei a me ke ana ʻana: Ma ke ʻano he kumu hōʻailona, ʻo ia ka "puʻuwai" o nā mea hana kiʻekiʻe e like me nā mea kālailai spectrum a me nā mea kālailai pūnaewele, e hōʻoiaʻiʻo ana i ka pololei o ka hoʻāʻo ʻana.
4. Nā mea hana ʻoihana a me nā mea ʻepekema: Hoʻohana ʻia no ka hoʻomehana ʻoihana, ka hoʻomaloʻo ʻana, a me nā mea hoʻolalelale ʻāpana a me ka hoʻomehana plasma no nā mea hana fusion nukelea ma nā kahua noiʻi ʻepekema.
5. Palekana a me ke kaua uila: Hoʻohana ʻia no nā ʻōnaehana kiʻi palekana kanaka a me nā mīkini jamming i ke kaua uila, e hana ana i nā hōʻailona paʻakikī e hoʻokō i ka hoʻopilikia.

Qualwavehāʻawi i kahi mea hana mana microwave paʻa me ka alapine (frequency) o 2.45GHz. Hoʻohana nui ʻia kā mākou huahana ma nā wahi he nui.
