Hangarau Ngaruiti o Sichuan Keenlion——Kaiwhakakotahi

Hangarau Ngaruiti Keenlion o Sichuan I whakatūria i te tau 2004, ko Sichuan Keenlion Mircrowave techenology CO., Ltd. te kaihanga matua o ngā wāhanga Mircrowave Whakakore i Sichuan Chengdu, Haina.

Ka whakaratohia e mātou ngā wāhanga whakaata-ngaru tino mahi me ngā ratonga e pā ana ki ngā tono ngaruiti i te kāinga me tāwāhi. He iti te utu o ngā hua, tae atu ki ngā momo wehewehe mana, ngā hononga aronga, ngā tātari, ngā whakakotahi, ngā takirua, ngā wāhanga kore mahi ritenga, ngā wehewehe me ngā porowhita. He mea hanga motuhake ā mātou hua mō ngā taiao me ngā pāmahana tino kino. Ka taea te whakatakoto i ngā whakatakotoranga kia rite ki ngā hiahia o te kiritaki, ā, e tika ana mō ngā roopu auau paerewa me ngā roopu auau rongonui katoa me ngā momo whānui mai i te DC ki te 50GHz.

Kaiwhakakotahi

I roto i te pūnaha whakawhitiwhiti waea pūkoro ahokore, ko te mahi matua o te whakakotahi ko te whakakotahi i ngā tohu maha-roopu whakauru me te whakaputa i aua tohu ki te pūnaha tohatoha o roto kotahi.

I roto i te tono hangarau, me whakaputa te whatunga C 800MHz, te whatunga G 900MHz, me ētahi atu auau rerekē rānei i te wā kotahi. Mā te whakamahi i te whakakotahitanga, ka taea e te huinga pūnaha tohatoha o roto te mahi i roto i te roopu auau CDMA, te roopu auau GSM, me ētahi atu roopu auau rānei i te wā kotahi.

Hei tauira, i roto i te pūnaha pūihi reo irirangi, ka honoa ngā tohu tāuru me ngā tohu tāuru o ngā momo auau rerekē (pēnei i te 145mhz me te 435mhz) mā te whakakotahi, kātahi ka honoa ki te teihana reo irirangi mā te whāngai, e kore e whakaora noa i te whāngai, engari ka karohia hoki te raruraru o te whakawhiti i ngā pūihi rerekē.

 

 

Epānga

I roto i ngā mahi hangarau, me whakakotahi te whatunga C 800MHz me te whatunga G 900MHz. Mā te whakamahi i te whakakotahi, ka taea e te huinga pūnaha tohatoha o roto te mahi i roto i te roopu CDMA me te roopu GSM i te wā kotahi. Hei tauira anō, i roto i te pūnaha pūihi reo irirangi, ka whakakotahihia ngā tohu whakauru me ngā tohu whakaputa o ngā roopu auau rerekē (pēnei i te 145mhz me te 435mhz) mā te whakakotahi, kātahi ka honoa ki te teihana reo irirangi me te whāngai, e kore e whakaora noa i te whāngai, engari ka karohia hoki te raruraru o te whakawhiti i ngā pūihi rerekē..

 

Whakaahuatanga o te whakarite matua

Ko te whakakotahi te mea e whakamahia whānuitia ana i te pito tuku. Ko tana mahi he whakakotahi i ngā tohu RF e rua, neke atu rānei, e tukuna ana mai i ngā tuku rerekē ki te kotahi, ka tukuna atu ki ngā taputapu RF e tukuna ana e te pūihi, me te karo hoki i te taunekeneke i waenga i ngā tohu o ia tauranga.

Ko ngā taputapu whakakotahi he rua, neke atu rānei ngā tauranga tāuru, ā, kotahi anake te tauranga putanga. He tohu nui te wehewehe tauranga hei whakaahua i te kaha o ngā tohu e rua ki te kore e pā tetahi ki tetahi. Ko te tikanga me neke atu i te 20dB.

E rua ngā tauranga tāuru me ngā tauranga putanga e rua o te whakakotahi piriti 3dB, e whakaaturia ana i te Pikitia 2. He mea whakamahi noa hei hanga i ngā auau kawe ahokore e rua, hei whāngai atu ki te pūihi, ki te pūnaha tohatoha rānei. Mena kotahi anake te tauranga putanga e whakamahia ana, me hono te tauranga putanga kē atu ki te kawenga 50W. I tēnei wā, ka ngaro te 3dB i muri i te whakakotahitanga o te tohu. I ētahi wā me whakamahi ngā tauranga putanga e rua, nō reira kāore he kawenga, kāore hoki he ngaronga 3dB.

Whakakotahitia te whiwhinga me te tuku tohu o te waea pūkoro ki te pūihi kotahi. I roto i te pūnaha GSM, nā te mea kāore te taputapu whakawhiti i te wā kotahi, ka taea e te waea pūkoro te tango i te taputapu takirua hei wehe i te taputapu whakawhiti, ā, ka whakamahia noa he taputapu whakawhiti ngāwari hei whakakotahi i ngā tohu tuku me te whiwhi ki te pūihi kotahi me te kore e pokanoa tetahi ki tetahi.

Mō te ara iahiko whiwhi, ka whiwhi te pūihi i te tohu, ka tomo ki te hongere whiwhi mā te whakakotahi, ka whakaranu ki te tohu oscillator ā-rohe i whiwhihia (arā, ko te tohu VCO i whiwhihia i hangaia e te synthesizer auau), ka huri i te tohu auau-tiketike hei tohu auau waenga, kātahi ka wetewetehia te tohu e te quadrature hei whakaputa i ngā tohu I me Q i whiwhihia; Kātahi ka whakahaerehia te wetewete GMSK (Gaussian filter minimum frequency shift keying) hei huri i te tohu anaro ki te tohu mamati, kātahi ka tukuna ki te wae tukatuka turanga.

Mō te ara iahiko tuku, ka tukuna e te wāhanga turanga te awa raraunga anga TDMA (me te tere o te 270.833kbit/s) mō te whakarerekētanga GSMK hei hanga i ngā tohu tuku I me Q, ka tukuna atu ki te kaitahuri tuku ake hei whakarerekētanga ki te roopu auau tuku. I muri i te whakanui mana, ka tukuna atu e te tuku mā te pūihi.

Ka whakaratohia e te whakahiato auau te tohu orooro ā-rohe e tika ana mō te tahuritanga auau mō te waeine tuku me te waeine whiwhi, ā, ka whakamahia te hangarau porowhita raka-wāhanga hei whakau i te auau. Ka whiwhi ia i te tohutoro auau mai i te ara iahiko tohutoro karaka.

Ko te ara iahiko tohutoro karaka he karaka 13mhz te tikanga. I tetahi taha, e whakarato ana i te tohutoro karaka mō te ara iahiko whakahiato auau me te karaka mahi mō te ara iahiko arorau.

Hei tāpiritanga, i roto i te whakamahinga o te whakakotahi, me mōhio ko te aratau whāngai tohu o te teihana turanga, o te pūrua rānei he ahokore, ā, ko tōna pūtake he whānuitanga whānui. Nō reira, me whaiti te whānuitanga whakawhiti i ētahi wā hei whakarite i te parakore o te tohu; ko te aratau whāngai tohu o te whakakotahi he taura, ā, ka tangohia tika te tohu mai i te pūtake, he tohu whānuitanga whāiti. Hei tauira, ko te whānui o te hongere CDMA / GSM o te whakakotahi jcdup-8026b he 800-960MHz. Ina uru atu ki te tohu auau kawe GSM, nā te mea he tohu auau kawe te pūtake, ko te tikanga whāngai he taura, ā, ko tēnei tohu auau kawe anake kei roto i te hongere me te kore he tohu whakararuraru kē atu. Nō reira, ka taea te hoahoa hongere whānui o te whakakotahi i roto i te whakamahinga mahi.

Ka taea hoki e mātou te whakarite i ngā wāhanga rf passive kia rite ki ō hiahia. Ka taea e koe te tomo ki te whārangi whakaritenga hei whakarato i ngā whakatakotoranga e hiahiatia ana e koe.
