He aha ka mea pale RF?

He aha ke kū'ē RF? I ka ʻōlelo maʻalahi, ua kapa ʻia nā kū'ē i hoʻohana ʻia i nā ʻōnaehana kamaʻilio microwave RF he mau kū'ē RF.
Pono nā kānaka a pau e kamaʻāina i ke au alapine (frequency frequency) o ke au lekiō, ʻo ia ka pōkole no nā nalu electromagnetic o ke au alapine (frequency) kiʻekiʻe.
ʻO ke au alapine kiʻekiʻe e loli ana ma mua o 10000 mau manawa i kekona ua kapa ʻia ʻo ia he au alapine lekiō.
He mea hana passive ka resistor RF e hiki ke ālai i ke kahe ʻana o ke au alapine lekiō. A hoʻololi i ka ikehu uila i ka wela a i ʻole nā ​​ʻano ikehu ʻē aʻe, me ke anakahi o ohms (Ω) e like me ke kū'ē maʻamau.

Hoʻokaʻawale pinepine ʻia nā mea pale RF ma muli o ka mana, a aia nā ʻano like ʻole e hoʻokaʻawale ai iā lākou:

Ma muli o ke ʻano o waho, hiki ke hoʻokaʻawale ʻia i:

1.Chip Resistor (ua māhele ʻia nā resistors chip i hoʻokahi electrode chip resistor a me nā dual electrode chip resistors)

2. Resistor Leaded (ua māhele ʻia nā resistors alakaʻi i nā resistors alakaʻi hoʻokahi a me nā resistors alakaʻi pālua)

3.Flanged Resistor (ua māhele ʻia nā resistors flanged i nā resistors flanged alakaʻi hoʻokahi a me nā resistors flanged pālua)

 

Wahi a ke ʻano o ke kaʻina hana, hiki ke hoʻokaʻawale ʻia i:

1. ʻO ke kū'ē RF kiʻiʻoniʻoni mānoanoa (i kapa ʻia ʻo ke kū'ē kiʻiʻoniʻoni mānoanoa)

2. Ke kū'ē'ē RF ki'i'oni'oni lahilahi (i kapa'ia he kū'ē'ē ki'i'oni'oni lahilahi)

 

Ma muli o ke ʻano o ka mana, hiki ke hoʻokaʻawale ʻia i:

1.ʻO ke kū'ē RF mana kiʻekiʻe (i kapa ʻia ʻo ke kū'ē mana kiʻekiʻe, e pili ana i nā kū'ē me ka mana o 60W a ʻoi aku paha)

2.Low power RF resistor (hoʻopōkole ʻia e like me ka resistor mana haʻahaʻa, e pili ana i nā resistors mana ma lalo o 20W)

 

Hoʻokaʻawale ʻia e ka alapine (frequency), hiki ke puʻunaue ʻia i:

1.ʻO ke kū'ē RF alapine kiʻekiʻe (i kapa ʻia ʻo ke kū'ē alapine kiʻekiʻe, ʻo ia hoʻi he kū'ē me ke alapine kiʻekiʻe ma mua o 3GHz)

2. Ke kū'ē RF alapine haʻahaʻa (hoʻopōkole ʻia e like me ke kū'ē alapine haʻahaʻa, ma ke ʻano he kū'ē me ka alapine haʻahaʻa ma mua o 3GHz)

 

Nā mea hana a me nā pono a me nā hemahema no ka hana ʻana i nā pale RF:

1. Loaʻa i ka Beryllium oxide (BeO) ke kiʻekiʻe o ka conductivity thermal, kokoke like me ke keleawe maʻemaʻe a me ka alumini, me ka coefficient conductivity thermal o 200-250W (mK), e lilo ia i mea makemake nui ʻia no ka hana ʻana i nā resistors RF. ʻO kona hemahema nui loa, he mea ʻawahia loa ia i ke ʻano pauka, e paʻakikī ai ka ho'ōla ʻana i nā ʻeha pili. No laila, ma ke ʻano laulā, kūʻai nā mea hana o nā resistors RF i nā mea pepa i hoʻoheheʻe ʻia a ʻaʻole pono ka hana lua. ʻO kēia ka hopena i ka hoʻohana ʻana i ka beryllium oxide (BeO) e hana i nā resistors RF hiki ke paʻi wale ʻia ma kahi chip hoʻokahi, e hōʻemi nui ana i ka pono o ka hana.

2. ʻO ka alumini nitride (AlN) kekahi mea me ka conductivity thermal kiʻekiʻe, me ka conductivity thermal ma kahi o 20W/mK. Loaʻa iā ia nā waiwai mechanical maikaʻi a me ka ikaika flexural kiʻekiʻe ma mua o ka alumini oxide a me nā beryllium oxide keramika. Ma muli o kona ʻano ʻawahia ʻole, hiki ke paʻi ʻia me ka hoʻohana ʻana i ka ʻenehana paʻi hoʻomau, hiki ke hoʻomaikaʻi nui i ka pono hana. I kēia manawa, ʻo ia ka mea makemake ʻia no nā resistors RF mana kiʻekiʻe.

3. ʻO ka alumini oxide (Al2O3) ka mea i makemake ʻia no nā pale pale ʻili haʻahaʻa, ʻoiai ʻo kona conductivity thermal ma kahi o 1/5 o ka alumini nitride. ʻAʻole hoʻohana pinepine ʻia i ke koho ʻana i nā mea no nā pale pale RF mana kiʻekiʻe.

 

RFTYTʻO Technology Co., Ltd. kahi mea hana ʻoihana o nā ʻāpana passive e like me nā RF resistors, RF attenuators, coaxial loads, coaxial attenuators, adjustable attenuators, RF isolators, RF circulators, etc.
Hoʻohana nui ʻia kāna huahana i nā ʻōnaehana e like me ka radar, nā mea kani, ka hoʻokele, ke kamaʻilio microwave multi-channel, ka ʻenehana lewa, ke kamaʻilio kelepona, ka hoʻoili kiʻi, a me nā kaapuni hoʻohui microwave.
Mai kona hoʻokumu ʻia ʻana, i mea e lawelawe maikaʻi aku ai i nā mea kūʻai aku a hāʻawi hou aku i ke kaiāulu, ua kālele ka ʻoihana i ka ʻenehana a ua hoʻomohala i nā microstrip isolators/circulators e kū nei i ka pae like me nā kūlana honua. ʻO nā hiʻohiʻona koʻikoʻi o ka huahana, ʻo ia ka palahalaha, ka liʻiliʻi, a me ke kaumaha māmā.
A he mau pono kona o ke kūlike maikaʻi a me ke kumukūʻai haʻahaʻa, e hoʻohana nui ʻia ana i nā kaapuni hoʻohui microwave. Me ka wikiwiki o ka hoʻomohala ʻana o nā ʻōnaehana microwave e like me ka radar phased array, e ʻoi aku ka maikaʻi o kā lākou mau manaʻolana noi.
E hoʻolaʻa mau ana ka ʻoihana iā ia iho i ka hoʻokō ʻana i nā pono o nā mea kūʻai aku, e hoʻoikaika ana e hoʻokumu i nā hiʻohiʻona kūikawā a hoʻomaikaʻi mau i ka maikaʻi o ka huahana, nā ʻano like ʻole, a me ka lawelawe. E hāpai i nā mea kūʻai aku me ko mākou naʻau, e hoʻoneʻe iā lākou me ko mākou mau manaʻo, a e loaʻa kahi inoa no ko mākou ʻoiaʻiʻo.
Ua lanakila mākou i ka hilinaʻi o kā mākou mea kūʻai aku me ka ʻenehana kiʻekiʻe, ke kūlana kiʻekiʻe, a me ka lawelawe kiʻekiʻe, e hoʻokō ana i ka pōmaikaʻi like a me ka hoʻolako ʻana i kahi nohona paʻa no ka ʻāina e hoʻokumu i kahi kaiāulu kūlike.
