An kwokunze kanyanga nokuda 3G-Modem - pokushandisa mudziyo zvinokonzera

Munhu wese anenge awana 3G-Modem, pakupedzisira anotarisana dambudziko murombo chiratidzo mabiko. Nechepakati shoma pamwero kunogona kubatsira zvokunze kanyanga pamusoro 3G-Modem. Kushandiswa kwaro anowedzera zvikuru ufanane akagamuchira chiratidzo. External kanyanga pamusoro 3G-Modem achibvumira kanoverengeka kuti rikurumidze nokupfuuridzirwa mashoko yepakutanga. Iye akaita mune nokupenya. Panyaya iyi, asiri kuonana adapteri. Vachataura kuzodzosera emit chiratidzo kubva Modem kusvika kwokunze kanyanga ndiEzekieri. Iyo vakawanda zano riri sezvinotevera: vanoda imwe zvokunze kanyanga nokuda 3G-Modem uye dzomunyika kanyanga RF unhu coaxial waya ane diki attenuation coefficient pa 2100 MHz. izvi zvose zvinogona kutengwa mumwe dzakagadzirirwa chitoro, asi iwe unogona kuita iwe mudziyo kwokunze.

External kanyanga pamusoro 3G-Modem nemaoko enyu - hazvina kuoma. Mumwe dzakasiyana kwezvinhu izvi zvaipiwa paIndaneti kazhinji. Izvi kanyanga Kharchenko pamusoro 3G-Modem. It Anonziwo "masere" nokuti maitiro chimiro. Hwaro nokuti Kharchenko waveguide, sere chakatodzana rhombuses maviri, izvo munyori wakatangwa pakugamuchira terevhizheni mugero ari UHF siyana. Zvisinei, kushandiswa kwayo sechinhu 3G chiratidzo mugamuchiri achafanira kuti zvimwe kuchinja magadzirirwo. Zvichakubatsira kusimbisa chiratidzo kana zviri. Kana GSM mureza hakusi zvavo, zvakanakisisa kushandisa zvakasiyana musimboti, yakaumbwa pachishandiswa yacho Satellite kanyanga. "Vasere" kuita kuti mhangura waya 4mm², izvo zvinogona kutengwa chero E-chitoro. Kubva waya loop hwakakungwa receiver. Izvi - mangoda maviri apamafudzi 53 mm uye maviri 120 ° pamakona kurutivi vertices rhombuses. "Vasere haina kubata panguva pakati sezvo pullback - dimikira, pane mhepo gwanza 5 neMM, uye ichi zvakakosha. Dunhu migumo dzakavharika ne pokunamatidza. Aluminum jira 2 mm gobvu ndiro anofanira kugera 140x140 neMM, izvo achaita somunhu reflector. In nechepakati ndiro mugomba akachera kuti waya ane dhayamita pakati 8-10 mm. Circuit vakatasva muna 36 mm pamusoro reflector. Akanga asiko kuva uchikurukura naye. Nokuti yechigarire uyu wakaitwa dielectric. Vanogona kuva epurasitiki. Zvino unofanira kusarudza sei wall-kugomo zvokusarudza. Unogona kushandisa chikomboredzo kubva Satellite dhishi. The kanyanga wire iri soldered. Zvinokurudzirwa kushandisa coaxial waya 75 Ohm. Zvisinei, izvozvo zvakaitika empirically kuti kana mabiko chinozunguzirwa 2100m Hz, izvo unoenderana HSDPA mureza, simba chiratidzo riri wakadenha zvokuti kana nemishonga pamusoro 50 ohms pakarepo decays. naizvozvo zvinganaka kushandisa waya ane impedance 50 ohms. waya akadaro anogona zvachose zvakagadzirwa nemhangura, uye zviri nyore kuisa pokunamatidza. The mudziyo inofanira kuiswa uye midzi panzvimbo. Panguva imwe mugumo waya rinoitwa matcher. Izvi zvinoda munhu foil mhangura. foil Izvi zvinogona kuwanikwa dismantling akwegura transformer, kana chete kutenga kubvira retailer. The foil anoitwa nyaya yaingowanikwa. Kurutivi rumwe pechifukidziro kuva 45 mm. Case usingatangi kugara zvakasimba pamusoro muviri wedu 3G mano.

Nokuti rakarukwa netambo vanoda chimedu foil kukura 27h76 mm. The chirukwa iri soldered kuti chidimbu ichi angazvidzvisa anofukidza pakavha, asi hapana asingadi chokuita naye uye chinoumba ari waya iri soldered kavha pachayo. Asiwo vanofanira zvakananga haana kubata muviri Modem. Kutaura zvazviri, imwe zvokunze kanyanga nokuda 3gG-Modem zvagadzirirwa kuti kushanda. Zvino tinoda chete kugadzira nayo nokungonyepedzera kutendeukira pagomo iri kunotsvaka chiratidzo womuchato.
