ʻO Solid-state microwave power generator 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 no ka hoʻoulu ʻana i nā hawewe electromagnetic microwave frequency (e pili ana i 300MHz~300GHz).

He ʻokoʻa loa ia mai nā "mea uila uila" maʻamau i nā kumu microwave e like me nā magnetrons, nā paipu nalu huakaʻi, a me nā klystrons. Ke hilinaʻi nei nā mea hana kuʻuna i ka neʻe ʻana o nā electrons manuahi i loko o ka vacuum e hoʻohua i nā microwaves, ʻoiai nā mea hana mana microwave solid-state e hilinaʻi holoʻokoʻa i nā ʻano o nā mea paʻa semiconductor, e hana ana i nā oscillations ma o ka neʻe a me ka neʻe ʻana o ka pae ikehu o nā electrons i loko o ka hoʻolālā lattice semiconductor.

Nā hiʻohiʻona:

1. ʻO ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā: ʻO ke kumu he semiconductor chip, ʻaʻole ia e koi i nā puʻupuʻu vacuum a i ʻole nā lako mana uila kiʻekiʻe, e hana i ka hāmeʻa holoʻokoʻa a maʻalahi e hoʻohui i nā ʻōnaehana uila hou.
2. ʻO ka uila haʻahaʻa haʻahaʻa a me ka palekana kiʻekiʻe: ʻO ka maʻamau he mau volts wale nō a hiki i nā ʻumi volts o ka mana haʻahaʻa haʻahaʻa DC e pono ai, ʻoiai nā mea uila uila e koi pinepine i nā tausani volts o ka volts kiʻekiʻe. ʻO kēia ka mea e palekana a maʻalahi ka hoʻolālā mana.
3. ʻO ke ola lōʻihi a me ka hilinaʻi kiʻekiʻe: Me ka ʻole o nā mea hoʻohana e like me nā filament cathode, lōʻihi loa ke ola ʻana o nā mea semiconductor, hiki i nā ʻumi a i ʻole haneli haneli mau hola, ʻoi aku ma mua o nā paipu microwave maʻamau.
4. Ka maʻemaʻe a me ka paʻa pinepine: ʻOi loa no nā kumu paʻa me ka hoʻohana ʻana i ka ʻenehana phase-locked loop (PLL), hiki iā lākou ke hana i nā hōʻailona microwave maʻemaʻe a paʻa loa me ka leo haʻahaʻa.
5. Hiki ke hoʻololi koke ʻia ka alapine hoʻopuka, ka pae, a me ka amplitude ma o ka volta (voltage controlled oscillator VCO) a i ʻole nā hōʻailona kikohoʻe, e maʻalahi ke hoʻokō i ka modulation paʻakikī a me ka agility.
6. Ka haʻalulu maikaʻi a me ka haʻalulu ʻana: Me kahi ʻano paʻa paʻa paʻa, ʻaʻohe pūpū aniani a i ʻole nā filament, e hiki ke hoʻololi ʻia i nā kaiapuni mechanical paʻakikī.

Noi:

1. ʻO ke kumu radar o kēia wā: Hoʻohana nui ʻia i ka radar nalu millimeter automotive, pūʻali pūʻali pūʻali hoʻonohonoho radar, a me nā mea ʻē aʻe, no ka loaʻa ʻana o ka ʻike pololei a me ka nānā ʻana i ke kukui wikiwiki.
2. Ke kahua kamaʻilio uila: He mea nui ia o nā kahua kahua 5G/6G, kamaʻilio ukali, a me nā lako hoʻoili microwave, kuleana no ka hoʻopuka ʻana i nā hōʻailona lawe alapine kiʻekiʻe.
3. ʻO ka hoʻāʻo pololei a me ke ana ʻana: Ma ke ʻano he kumu hōʻailona, ʻo ia ka "naʻau" o nā mea hana kiʻekiʻe e like me nā spectrum analyzers a me nā mea nānā pūnaewele, e hōʻoiaʻiʻo ana i ka pololei o ka hoʻāʻo.
4. Nā mea hana ʻenehana a me ka ʻepekema: Hoʻohana ʻia no ka hoʻomehana ʻana i ka ʻoihana, ka hoʻomaloʻo ʻana, a me nā mea wikiwiki a me ka hoʻomehana plasma no nā mea hoʻohui nuklea 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 ke keakea.

Kaʻaleʻalehāʻawi i kahi mea hana mana microwave me ka alapine o 2.45GHz. Hoʻohana nui ʻia kā mākou huahana ma nā wahi he nui.
