Kana iwe wakamboshandisa RF (redhiyo frequency) kutaurirana, maserura network, kana antenna masisitimu, unogona kusangana neizwi LMR tambo. Asi chii chaizvo uye nei ichishandiswa zvakanyanya? Muchinyorwa chino, tichaongorora kuti LMR tambo chii, hunhu hwayo hwakakosha, uye nei iri sarudzo inosarudzika yeRF zvikumbiro, topindura mubvunzo 'Chii chinonzi LMR tambo?'.
Nzwisisa LMR coaxial tambo
LMR tambo ndeye coaxial tambo yakagadzirirwa kushanda kwepamusoro, yakaderera kurasikirwa chiratidzo chekufambisa muRF zvikumbiro. LMR tambo dzinogadzirwa neTimes Microwave Systems uye dzinozivikanwa nekudzivirira kwadzo, kuderera kwechiratidzo kurasikirwa, uye kusimba, zvichiita kuti dzive dzakanakira kutaurirana isina waya GPS, Yakanakira sarudzo radar uye mamwe maRF akavakirwa masisitimu. Kusiyana netambo dzekoaxial dzechinyakare, tambo dzeLMR dzakagadzirwa nemateru akawanda ekudzivirira uye dielectric zvinhu kuti ive nechokwadi chekuvimbika kwechiratidzo. Ivo vanouya muhukuru hwakasiyana-siyana kusarudza kubva, seLMR-195, LMR-240, LMR-400, uye LMR-600, imwe neimwe yakagadzirirwa akasiyana ekugadzirisa simba uye chiratidzo chekurasikirwa zvinodiwa.
Hunhu hunhu hweLMR coaxial tambo
LMR tambo dzinomira pachena mumunda wecoaxial tambo nekuda kwechimiro chavo chakasiyana uye mabhenefiti ekuita:
1. Kurasikirwa kwechiratidzo chepasi
Imwe yemabhenefiti akanyanya kukosha eLMR tambo dzine yakaderera chiratidzo kurasikirwa ndiko kuderera kwavo kuderera pamusoro pemarefu madaro (chiratidzo kurasikirwa). Izvi zvinowanikwa kuburikidza nepamusoro-soro dielectric insulation uye shielding, iyo inoderedza kurasikirwa kwesimba kana zviratidzo zvichipfuura nematambo.
2. Excellent shielding performance
LMR tambo dhizaini ine akawanda ekudzivirira akaturikidzana, kazhinji anosanganisira aluminium strip shielding yepakutanga EMI (electromagnetic interference) kudzivirira. Kuruka kudzivirirwa kwekunze kunowedzera kusimba uye kunoderedza kupindira. Kudzivirira uku kunovimbisa masiginecha akasimba uye akajeka, zvichiita kuti tambo dzeLMR ive sarudzo yakanaka kune inonzwira tsitsi RF application.
3. Kugara uye kuramba kwemamiriro ekunze
Times Microwave Systems inogadzira tambo dzeLMR, ane sheath yakasimba yekunze yakagadzirwa ne polyethylene (PE) kana thermoplastic elastomer (TPE), zvichiita kuti isarambe kune ultraviolet mwaranzi, mwando, uye tembiricha yakanyanyisa. Mimwe misiyano, senge LMR-UF (Ultra Flex), inopa imwe shanduko yekumisikidza inoda kugara uchikotama uye kufamba.
4. Flexible uye nyore kuisa
Kuenzaniswa neyechinyakare dzakaomesesa coaxial tambo, LMR tambo dzine yakakwirira kuchinjika uye huremu, zvichiita kuti kuisirwa kuve nyore. Radhiyasi yavo yekupeta idiki zvakanyanya pane iya yakafanana neRF tambo, iyo inobvumira kuisirwa kwakasimba munzvimbo dzakavharirwa.
5. Kuenderana neRF connectors
LMR tambo dzinotsigira akawanda anobatanidza, kusanganisira N-mhando yekubatanidza (inowanzo shandiswa muantenna uye RF zvikumbiro). SMA connector (yewireless uye GPS masisitimu). BNC yekubatanidza (inozivikanwa mukutepfenyura uye networking). Uku kugarisana kunoita kuti vakwanise kuita zvakasiyana mumaindasitiri akasiyana.
Zvakajairwa Zvishandiso zveLMR Cables
Nekuda kwekuita kwayo kwakanaka, tambo dzeLMR dzinoshandiswa zvakanyanya mumaindasitiri anovimba neRF kutaurirana. Zvimwe zvezvinonyanya kushandiswa zvinosanganisira wireless uye cellular network, antenna neRF masisitimu, GPS uye setiraiti kutaurirana, aerospace application, yekutarisa nekuchengetedza masisitimu.
Sarudza iyo chaiyo LMR tambo
Kusarudzwa kweiyo chaiyo LMR tambo mhando kunoenderana nezvakati wandei, zvinosanganisira frequency, chinhambwe, kubata kwesimba, uye mamiriro ezvakatipoteredza. Hedzino dzimwe sarudzo dzakajairika:
LMR-195 uye LMR-240: Inokodzera mapfupi-renji maapplication akadai seWi Fi antennas uye GPS masisitimu.
LMR-400: Yakaderera kurasikirwa yepakati-renji sarudzo inowanzoshandiswa mumaserura uye maviri-nzira redhiyo masisitimu.
LMR-600: Yakanyatsokodzera kunyorera kureba uko kurasikirwa kwechiratidzo kunofanirwa kudzikiswa zvakanyanya.
Kana iwe uchida kuchinjika kwemafoni ekushandisa, LMR-UF (Ultra Flex) tambo zvakare isarudzo yakanaka.
