ʻO Sichuan Keenlion Microwave Technology——Mea hoʻohui

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.

Mea hoʻohui

I loko o ka ʻōnaehana kelepona kelepona ʻole, ʻo ka hana nui o ka combiner ka hoʻohui ʻana i nā hōʻailona multi band input a hoʻopuka iā lākou i ka ʻōnaehana hoʻolaha i loko.

Ma ka noi ʻenehana, pono e hoʻopuka ʻia ka pūnaewele 800MHz C, 900MHz G a i ʻole nā ​​alapine ʻē aʻe i ka manawa like. Me ka hoʻohana ʻana i ka hui hui, hiki i kahi pūnaehana hoʻolaha i loko ke hana ma ka CDMA frequency band, GSM frequency band a i ʻole nā ​​​​mea alapine ʻē aʻe i ka manawa like.

No ka laʻana, i loko o ka ʻōnaehana antenna radio, ua hui pū ʻia nā hōʻailona hoʻokomo a me nā mea hoʻopuka o nā ʻāpana alapine like ʻole (e like me 145mhz a me 435mhz) ma o ka hui pū ʻana, a laila pili pū me ka lekiō me kahi mea hānai, ʻaʻole ia e mālama wale i kahi mea hānai, akā pale pū nō hoʻi i ka pilikia o ka hoʻololi ʻana i nā antenna like ʻole.

 

 

Effect

I nā noi ʻenehana, pono e hoʻohui i ka pūnaewele 800MHz C a me ka pūnaewele 900MHz G. Me ka hoʻohana ʻana i ka hui hui, hiki i kahi pūnaehana hoʻolaha i loko ke hana ma ka band CDMA a me ka band GSM i ka manawa like. No kekahi laʻana, i loko o ka ʻōnaehana antenna radio, ua hui pū ʻia nā hōʻailona hoʻokomo a me nā mea hoʻopuka o nā ʻāpana alapine like ʻole (e like me 145mhz a me 435mhz) ma o ka hui pū ʻana, a laila pili pū me ka lekiō me kahi mea hānai, ʻaʻole ia e mālama wale i kahi mea hānai, akā pale pū kekahi i ka pilikia o ka hoʻololi ʻana i nā antenna ʻokoʻa..

 

Ka wehewehe analogy kumu

Hoʻohana maʻamau ka mea hui ma ka hopena hoʻouna. ʻO kāna hana ʻo ka hoʻohui ʻana i ʻelua mau hōʻailona RF i hoʻouna ʻia mai nā transmitters like ʻole i hoʻokahi a hoʻouna iā lākou i nā mea RF i hoʻouna ʻia e ka antenna, ʻoiai e pale ana i ka pilina ma waena o nā hōʻailona o kēlā me kēia awa.

Loaʻa i nā mea hui pū ʻelua a ʻoi aku paha nā awa hoʻokomo a hoʻokahi wale nō puka puka. ʻO ka hoʻokaʻawale ʻana i ke awa he kuhikuhi nui e wehewehe i ka hiki o nā hōʻailona ʻelua ke pili ʻole kekahi i kekahi. Pono e ʻoi aku ma mua o 20dB.

ʻO 3dB bridge combiner ʻelua mau awa hoʻokomo a me ʻelua mau puka puka, e like me ka hōʻike ʻana ma ke Kiʻi 2. Hoʻohana maʻamau ia e synthesize ʻelua mau alapine uila a hānai iā lākou i loko o ka antenna a i ʻole ka ʻōnaehana hoʻolaha. Inā hoʻohana ʻia hoʻokahi awa puka, pono e hoʻopili ʻia ke awa puka ʻē aʻe i kahi ukana 50W. I kēia manawa, aia he 3dB nalowale ma hope o ka hui ʻana o ka hōʻailona. I kekahi manawa pono e hoʻohana ʻia nā awa puka ʻelua, no laila ʻaʻohe ukana a ʻaʻohe poho 3dB.

E hoʻohui i ka loaʻa ʻana a me ka hoʻouna ʻana o ke kelepona paʻalima i hoʻokahi antenna. Ma ka ʻōnaehana GSM, no ka mea ʻaʻole ka transceiver i ka manawa like, hiki i ke kelepona paʻa ke haʻalele i ka duplexer no ka hoʻokaʻawale ʻana i ka transceiver, a hoʻohana wale i kahi mea hoʻohui transceiver maʻalahi e hoʻohui i ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona i hoʻokahi antenna me ka ʻole e hoʻopilikia kekahi i kekahi.

No ke kaapuni kaʻapuni, loaʻa ka antenna i ka hōʻailona, ​​​​e komo i ke kahawai hoʻokipa ma o ka hui pū ʻana, hui pū me ka hōʻailona oscillator kūloko i loaʻa (ʻo ia ka hōʻailona VCO i hana ʻia e ka frequency synthesizer), hoʻololi i ka hōʻailona alapine kiʻekiʻe i kahi hōʻailona alapine waena, a laila hoʻohaʻahaʻa ʻia ka quadrature i ka hōʻailona e hana i nā hōʻailona I a me Q i loaʻa; A laila, lawe ʻia ka demodulation e hoʻohuli i ka hōʻailona analog i ka hōʻailona kikohoʻe, a laila hoʻouna ʻia i ka ʻāpana hana baseband.

No ke kaapuni hoʻouna, hoʻouna ka ʻāpana baseband i ke kahawai data frame TDMA (me ka wikiwiki o 270.833kbit / s) no ka modulation GSMK e hana i nā hōʻailona I a me Q, a laila e hoʻouna ʻia i ka mea hoʻololi hoʻouna no ka hoʻololi ʻana i ka band frequency transmission. Ma hope o ka hoʻonui ʻana i ka mana, hoʻouna ka transmitter iā ia e ka antenna.

Hāʻawi ka frequency synthesizer i ka hōʻailona oscillator kūloko e pono ai no ka hoʻololi pinepine ʻana no ka hoʻouna ʻana a me ka loaʻa ʻana, a hoʻohana i ka ʻenehana loop-locked loop e hoʻopaʻa i ke alapine. Loaʻa iā ia ka kuhikuhi alapine mai ke kaapuni kuhikuhi uaki.

ʻO ka uaki kuhikuhi kaapuni maʻamau he 13mhz uaki. Ma ka lima hoʻokahi, hāʻawi ia i ka ʻōlelo kuhikuhi no ka kaʻapuni synthesis frequency a me ka uaki hana no ka kaapuni logic.

Hoʻokaʻawale nui

Mea hui alapine pālua

Hoʻokahi puka i uhi i ka tetra / iden, CDMA a me GSM pūnaewele alapine (800-960MHz), a hiki ke hoʻokomo i ka tetra / iden, CDMA, GSM a i ʻole kekahi hui pū ʻana o ia mea; ʻO ke awa ʻē aʻe ka uhi ʻana i ka pā alapine o DCS, PHS, 3G a me WLAN ʻōnaehana (1710-2500mhz), a hiki ke hoʻokomo i ka DCS, PHS, 3G, WLAN a i ʻole kekahi hui pū ʻana o ia mau mea.

④ JCDUP-8022

(CDMA / GSM / DCS / 3G) & WLAN mea hoʻohui ʻelua alapine he mea ʻelua i loko a hoʻokahi i waho. Hoʻokahi awa e uhi i ka CDMA, GSM, DCS a me 3G system frequency band (824-960 / 1710-2170mhz), a hiki ke hoʻokomo i ka CDMA, GSM, DCS, 3G a i ʻole kekahi hui pū ʻana; Ua uhi ʻia ke awa ʻē aʻe i ka pūnaewele ʻōnaehana WLAN (2400-2500mhz) a hiki ke hoʻokomo i nā hōʻailona ʻōnaehana WLAN.

ʻEkolu alapine hoʻohui

① JCDUP-8024 / JCDUP-8024B

ʻO GSM & DCS & 3G ʻekolu mea hoʻohui alapine he ʻekolu i loko a hoʻokahi i waho. Hiki ke hoʻohui ʻia nā hōʻailona GSM (885-960mhz), DCS (1710-1880mhz) a me 3G (1920-2170MHz).

ʻEhā hoʻohui pinepine

① JCDUP-8031

ʻO GSM & DCS & 3G & WLAN ʻehā mea hoʻohui alapine he ʻehā ma ka hoʻokahi. ʻO GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) a me WLAN (2400-2483.5mhz) hiki ke hoʻohui ʻia nā hōʻailona alapine ʻehā.

Eia kekahi, i ka hoʻohana ʻana i ka combiner, pono e hoʻomaopopo ʻia ʻo ke ʻano hānai hōʻailona o ka base station a i ʻole repeater he uea ʻole, a ʻo kona kumu he ākea ākea. No laila, koi ʻia ka passband haiki i kekahi mau hihia e hōʻoia i ka maʻemaʻe o ka hōʻailona; ʻO ke ʻano hānai hōʻailona o ka hui pū ʻana he uwea, a lawe pololei ʻia ka hōʻailona mai ke kumu mai, ʻo ia ka hōʻailona kikoʻī. No ka laʻana, ʻo ka CDMA / GSM channel o combiner jcdup-8026b he ākea ākea o 800-960MHz. I ke komo ʻana i kahi hōʻailona alapine lawe GSM, no ka mea, ʻo ke kumu he hōʻailona alapine lawe, ʻo ke ala hānai ʻana he uwea, a aia wale nō kēia hōʻailona alapine lawe i ke kahawai me nā hōʻailona ʻē aʻe. No laila, hiki ke hoʻolālā ʻia ke ala ākea o ka combiner i ka hoʻohana pono.

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.
