He pūihi waho mō te 3G-pouwhanga - tono o nga take pūrere

tangata katoa e kua riro 3G-pouwhanga, maoro, anga te raruraru o te fariiraa tohu rawakore. I tona taumata iti e taea te āwhina pūihi waho o 3G-pouwhanga. Ko tōna whakamahi nui faarahi te taumata o te tohu riro. Waho pūihi o 3G-pouwhanga taea e rave rahi taime ki te tere ake te tuku o te mōhiohio taketake. i mahi ia i roto i te uira. I roto i tenei take, te whāurutau whakapā-kore. ka anō-emit ratou te tohu i te pouwhanga ki te pūihi waho, me te te hurihia. E ko, te kaupapa whānui ko e whai ake: hiahia kotahi pūihi waho mō te 3G-pouwhanga me te ā pūihi RF kounga taura tafenga he whakarea attenuation iti i 2100 MHz. tenei katoa e taea te hokona i te toa makehe, engari ka taea e hanga e koe koe he pūrere waho.

hoahoa ohie

pūihi waho o 3G-pouwhanga ki o koutou ringa - e kore te reira pakeke. Ko tētahi o nga rerekē o tenei hoahoa kua whakaekea ki runga ki te Internet tino pinepine. pūihi tenei Kharchenko o 3G-pouwhanga. Kei te hoki i huaina te reira "e waru" mo te āhua āhuatanga. Ko te pūtake hoki reira ko Kharchenko waveguide, waru ahua rua rhombuses, i whakaarohia ana te kaituhi mō te fariiraa i takere pouaka whakaata i roto i te awhe UHF. Heoi, i tona whakamahi rite te tohu kaiwhiwhi 3G ka whai ki te hanga i te tahi mau huringa i roto i te hoahoa. E tauturu te reira ki te whakapakari i te tohu, ki te he te reira. Ki te kore ko te tohu GSM i roto i te whānui, he reira pai ki te whakamahi i te whakatinanatanga rerekē, i hanga i runga i te kaupapa o te pūihi amiorangi. "Waru" ki te mahi o te parahi waea 4mm², e taea te hokona i roto i tetahi E-toa. Mai i te farii piko koropiko waea. Tenei - e rua taimana ki taha e 53 mm me rua 120 ° koki i runga i nga rhombuses akitu taha o. "E kore te waru hono i te pokapū rite te pullback - he ahua, i reira he he rangi āputa 5 mm, me he nui tenei. E katia pito iahiko i te whakapiringa. Me tapahi te whārangi Aluminium 2 mm pereti matotoru 140x140 mm, e ka mahi rite te whakaata. I roto i te pokapū o te poka pereti tāne mo te taura ki te diameter 8-10 mm o. eke Circuit i roto i 36 mm runga ake te reflector. I wahi ia ki te hei i roto i te whakapā ki a ia. hanga hoki tenei kēmu e o te uruhanga. Ka taea e waiho ratou kirihou. Na e hiahia ana koe ki te whakatau me pehea ki te taiepa-Maunga kōwhiringa. Ka taea e koe te whakamahi i te taiapa i te rihi amiorangi. soldered te taura pūihi te. E tūtohu ana ki te whakamahi i te taura tafenga 75 Ohm. Heoi, ka tahuri te reira i roto i empirically e ka te fariiraa poipoi 2100m Hz, e hāngai ana ki te paerewa HSDPA, hangaia te tohu mana e taua e, no te tonu pirau te ātete i runga 50 ohms. Kei te reira anihia ki te whakamahi i te taura ki te parenga ia o 50 ohms. tino kia te waea taua hanga o parahi, a he mea ohie ki te tāpiri whakapiringa. Me tāuta te pūrere, ka punga i wahi. I te tahi atu pito o te taura whakamana te Rite. Tenei ka rapua e te konumohe parahi. Ka taea te whiwhi i tēnei kinaki i tuuraki i te hiko tawhito, hoko noa i te reira i te toa ranei. hanga te kinaki te take i rawe ki. Ko tētahi taha o te taupoki ki te kia 45 mm. e kore e Case noho raru i runga i te tinana o to tatou whakaaro 3G.

Hoki whiri Me taura i te wahi o te konumohe te rahi 27h76 mm. soldered te whiri e ki tenei wahi o te konumohe e hipokina te taupoki, engari wahi e kore e whakaaro ki a ia, ka soldered te matua o te waea e ki te taupoki ake. Otiia e kore e e te reira pa ki tika ano te tinana o te pouwhanga. I roto i te meka, he rite hoki te mahi hei pūihi waho mo 3gG-pouwhanga. Me anake Na ki te whirihora i te reira na roto i te tahuri noa i runga i te maunga i roto i te rapu o te fariiraa pai tohu.
