ʻO Sichuan Keenlion Microwave Technology——Passive device

ʻO Sichuan Keenlion Microwave Technology I hoʻokumu ʻia ma 2004, ʻo Sichuan Keenlion Mircrowave techenology CO., Ltd. ka mea hana nui o nā ʻāpana Passive Mircrowave ma Sichuan Chengdu, Kina.
Hāʻawi mākou i nā ʻāpana mirrowave kiʻekiʻe a me nā lawelawe pili no nā noi microwave ma ka home a ma waho. ʻO nā huahana ke kumu kūʻai, me nā mea hoʻokaʻawale mana like ʻole, nā mea hoʻopili kuhikuhi, nā kānana, nā hui pū, nā duplexers, nā ʻāpana passive i hana ʻia, nā mea hoʻokaʻawale a me nā circulators. Hoʻolālā kūikawā ʻia kā mākou huahana no nā kaiapuni koʻikoʻi a me nā mahana. Hiki ke hoʻonohonoho ʻia nā kikoʻī e like me nā koi o ka mea kūʻai aku a pili i nā mea āpau maʻamau a kaulana hoʻi me nā bandwidth like ʻole mai DC a 50GHz.

ʻO nā mea hana paʻa
He papa koʻikoʻi nā ʻenehana passive o ka microwave a me nā polokalamu RF, kahi mea nui i ka ʻenehana microwave. ʻO nā ʻāpana passive ka nui o nā resistors, capacitors, inductors, converters, gradients, nā hui like, resonators, filters, mixers a me nā hoʻololi.

ʻAno hāmeʻa
Hoʻolauna ʻano ʻano
ʻO nā ʻāpana passive ka nui o nā resistors, capacitors, inductors, converters, gradients, nā hui like, resonators, filters, mixers a me nā hoʻololi. He mea uila hiki ke hōʻike i kona mau hiʻohiʻona me ka ʻole o ka mana waho. ʻO nā ʻāpana passive ka nui o ka resistive, inductive a me nā mea capacitive. ʻO kā lākou hiʻohiʻona maʻamau hiki iā lākou ke hana inā loaʻa kahi hōʻailona me ka ʻole o ka hoʻohui ʻana i ka mana i ke kaapuni.

mea pale pale
Ke hele ka au i ke au, ʻo ka waiwai i hoʻopaʻa ʻia e ke kūʻē kūloko o ka mea hoʻokele i ke au i kapa ʻia ʻo resistance. ʻO nā ʻāpana e pāʻani ana i ke ʻano o ka pale ʻana i kēia manawa i ke kaapuni i kapa ʻia he resistors, i kapa ʻia he resistors no ka pōkole. ʻO ke kumu nui o ka resistor ʻo ia ka hoʻohaʻahaʻa i ka volta, hoʻokaʻawale i ka volta a i ʻole shunt. Hoʻohana ʻia ʻo ia ma ke ʻano he ukana, manaʻo manaʻo, hoʻopili, hoʻokaʻawale, etc.
ʻO ka hōʻailona o ke kū'ē i ke kiʻi kaapuni ʻo ia ka leka R. ʻO ka ʻāpana maʻamau o ke kū'ē ʻana ʻo Ohm, i kākau ʻia ʻo Ω. ʻO ka kiloohm KΩ a me megaohm mΩ ka mea maʻamau.
IKΩ=1000Ω 1MΩ=1000KΩ

capacitor
ʻO ka Capacitor kekahi o nā mea maʻamau i nā kaapuni uila. He mea ia no ka mālama ʻana i ka ikehu uila. Hoʻokumu ʻia ka capacitor i ʻelua conductors o ka nui like a me ka maikaʻi sandwiched me kahi papa o ka insulating medium. Ke hoʻohana ʻia ka volta i nā ʻaoʻao ʻelua o ka capacitor, mālama ʻia kahi uku uila ma ka capacitor. I ka manawa ʻaʻohe volta, ʻoiai aia kahi kaapuni paʻa, e hoʻokuʻu ia i ka ikehu uila. Kāohi ka capacitor i ka hele ʻana o DC ma ke kaapuni a hiki i ka AC ke hele. ʻO ke kiʻekiʻe o ke alapine o AC, ʻoi aku ka ikaika o ka hiki ke hele. No laila, hoʻohana pinepine ʻia nā capacitors i nā kaapuni no ka hoʻopili ʻana, ke kāʻei ʻana i ke kānana, ka pane ʻana, ka manawa a me ka oscillation.
ʻO ka helu leka o ka capacitor ʻo C. ʻO ka ʻāpana o ka capacitance he farad (i hoʻopaʻa ʻia e like me f), i hoʻohana mau ʻia ʻo μF (micro method), PF (ie μμF. Pico method).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
ʻO nā hiʻohiʻona o ka capacitance ma ke kaapuni he nonlinear. Ua kapa ʻia ka impedance i kēia manawa capacitive reactance. Hoʻohālikelike ʻia ka capacitance reactance i ka capacitance a me ke alapine hōʻailona.

Mea hoʻohuihui
E like me ka capacitance, ʻo ka inductance kekahi mea mālama ikehu. Hana ʻia nā inductors me nā coils. Ke hoʻohana ʻia ka volta AC ma nā ʻaoʻao ʻelua o ka coil, hoʻokumu ʻia ka ikaika electromotive i loko o ka coil, ka mea e pale ai i ka hoʻololi ʻana o ka manawa e hele ana i ka coil. Kapa ʻia kēia ʻākeʻakeʻa i ke kūʻē inductive. ʻO ka reactance inductive e pili pono i ka inductance a me ke alapine o ka hōʻailona. ʻAʻole ia e pale i ka DC o kēia manawa (me ka nānā ʻole i ke kūpaʻa DC o ka coil). No laila, ʻo ke kuleana o ka inductance i nā kaapuni uila: ka pale ʻana i kēia manawa, ka hoʻololi ʻana o ka volta, ka hoʻopili ʻana a me ka hoʻohālikelike ʻana me ka capacitance no ke kani ʻana, kānana ʻana, koho pinepine ʻana, ka mahele pinepine, etc.
ʻO ke code o ka inductance ma ke kaapuni ʻo L. ʻO Henry ka ʻāpana o ka inductance (i hoʻopaʻa ʻia ʻo H), a ʻo nā mea maʻamau ʻo milliheng (MH) a me micro Heng（μH).
1H=1000mH 1mH=1000μH
ʻO ka inductance kahi mea maʻamau o ka induction electromagnetic a me ka hoʻololi electromagnetic. ʻO ka noi maʻamau ka transformer.

Kuhikuhi hoʻomohala
1. ʻO ka modularization hoʻohui ʻia ke ʻano hoʻomohala e hiki mai ana o nā ʻāpana passive. Hāʻawi ka module hoʻohui i ka hiki ke hoʻohui i nā mea hana a i ʻole nā ​​modula a me nā ʻāpana passive, a hoʻokō i nā koi o ka hoʻemi ʻana o ka module a me ke kumu kūʻai haʻahaʻa i ka manawa like. ʻO nā ʻano kumu nui: haʻahaʻa haʻahaʻa co fired ceramic technology (LTCC), ʻenehana kiʻiʻoniʻoni lahilahi, silicon wafer semiconductor ʻenehana, ʻenehana papa kaapuni multilayer, etc.
2. Hoʻonui liʻiliʻi. ʻO ka ʻimi ʻana i ka miniaturization a me ka māmā ma ka ʻoihana uila e pono ai nā mea passive e hoʻomohala i kahi ala liʻiliʻi. Hoʻohana nui ʻia ʻo Micro electro mechanical system (MEMS) e hana i nā ʻāpana RF liʻiliʻi, haʻahaʻa haʻahaʻa, ʻoi aku ka ikaika a ʻoi aku ka maikaʻi o ka hoʻohui ʻana.
3. Encapsulation hopena. Hoʻohālikelike ʻia me nā ʻāpana passive maʻamau i hoʻohana ʻia, hiki i ka hoʻohui ʻana o nā ʻāpana i loko o ka pōʻai ke hoʻomaikaʻi maikaʻi i ka hilinaʻi o ka ʻōnaehana, hoʻopōkole i ke ala conductive, hōʻemi i nā hopena parasitic, hoʻemi i nā kumukūʻai a hoʻemi i ka nui o nā mea hana.

Nā ʻokoʻa ma waena o nā mea hana a me nā mea passive
ʻO nā hāmeʻa passive nā mea hiki ke hōʻike i ko lākou mau hiʻohiʻona kūʻokoʻa me ka ʻole o ka mana o waho (DC a i ʻole AC). Ma waho aʻe, aia nā mea hana hana. ʻO ka mea i kapa ʻia ʻo "ʻano waho" ka wehewehe ʻana i kahi nui pili o ka mea hana, ʻoiai ke hoʻohana ʻia ka volta a i ʻole ke au, ke kahua uila a i ʻole ke kahua magnetic, ke kaomi a i ʻole ka wikiwiki a me nā nui ʻē aʻe e wehewehe i kona pilina.

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.
