I del 1<\/a> av den h\u00e4r serien utforskade vi antennens betydelse f\u00f6r att tillhandah\u00e5lla en p\u00e5litlig och motst\u00e5ndskraftig data- eller r\u00f6stkommunikationsl\u00e4nk. I denna avslutande del unders\u00f6ker vi p\u00e5 vilket s\u00e4tt det \u00e4r lika viktigt att v\u00e4lja r\u00e4tt kabel och kontakt.<\/p>\n\n\n\n

Som vi uppt\u00e4ckte fr\u00e5n del 1<\/a>, \u00e4r prestandan hos en tr\u00e5dl\u00f6s s\u00e4ndare beroende av varje komponent, fr\u00e5n utg\u00e5ngen hos s\u00e4ndarens ffektf\u00f6rst\u00e4rkarsteg till antennen, inklusive \u00f6verf\u00f6ringslinan och anslutningarna som anv\u00e4nds. Detta tillv\u00e4gag\u00e5ngss\u00e4tt \u00e4r lika viktigt f\u00f6r den mottagna signalv\u00e4gen, d\u00e4r l\u00e5ga \u00b5V-signaler \u00e4r involverade. F\u00f6r de flesta l\u00e5geffekt-RF-till\u00e4mpningar, s\u00e5 som Wi-Fi, Bluetooth, LTE, \u00e4r \u00f6verf\u00f6ringslinan enkel, vanligtvis bara en l\u00e4ngd koaxialkabel.<\/p>\n\n\n\n

Koaxialkabelspecifikationer<\/h2>\n\n\n\n

En typisk koaxialkabel (vanligen f\u00f6rkortad koax) innefattar en inre mittledare, vanligtvis koppar, omgiven av en dielektrisk plastk\u00e4rna, som i sin tur \u00e4r t\u00e4ckt av ett eller flera ledande skikt, och sedan en slutlig yttre mantel. Mittledaren kan vara av en enda solid k\u00e4rna, eller vanligen flertr\u00e5dig. Den yttre ledaren innefattar som regel en f\u00f6rtennad kopparfl\u00e4ta, och ibland en extra kopparfolie f\u00f6r att ge ytterligare avsk\u00e4rmning. Den yttre manteln ger ett yttre fysiskt skyddande lager och f\u00f6rhindrar att fukt och smuts tr\u00e4nger in.<\/p>\n\n\n\n

Den totala diametern p\u00e5 en koaxialkabel har en betydande inverkan p\u00e5 dess vikt per meter och minsta b\u00f6jradie. D\u00e4remot best\u00e4mmer elektriska faktorer vilken konstruktionsmetod som anv\u00e4nds och vilka l\u00e4mpliga applikationer.<\/p>\n\n\n\n

Viktiga koaxialkabelparametrar<\/h2>\n\n\n\n

Karakteristisk impedans:<\/strong> Impedans \u00e4r ett viktigt urvalskriterium och m\u00e5ste matcha antennen i ena \u00e4nden och s\u00e4ndaren eller mottagaren i den andra \u00e4nden f\u00f6r att uppn\u00e5 h\u00f6gsta signal\u00f6verf\u00f6ringseffektivitet. De flesta koaxialkablar \u00e4r tillg\u00e4ngliga med antingen 50 Ohm eller 75 Ohm impedans, d\u00e4r professionella applikationer vanligtvis \u00e4r 50 Ohm. Impedansen f\u00f6r en koaxialkabel \u00e4r komplex och kan kr\u00e4va en unders\u00f6kning av den dielektriska kapacitansen mellan mitten och de yttre ledarna.<\/p>\n\n\n\n

F\u00f6rlust eller d\u00e4mpning:<\/strong> Lika viktigt som urvalskriterie \u00e4r en kabels f\u00f6rlust- eller d\u00e4mpningsegenskaper. Typiskt angivna i dB per 100 meter, och vid ett antal frekvenser, indikerar d\u00e4mpningsegenskaperna hur mycket s\u00e4ndareffekt eller mottagen signal som g\u00e5r f\u00f6rlorad l\u00e4ngs dess l\u00e4ngd. Kabelns resistiva och dielektriska egenskaper p\u00e5verkar avsev\u00e4rt dess d\u00e4mpningsegenskaper.<\/p>\n\n\n\n

Effekthanteringskapacitet:<\/strong> Den maximala effektkapaciteten f\u00f6r en kabel beror p\u00e5 flera faktorer, inklusive topparbetssp\u00e4nning som dielektrikumet kan motst\u00e5, resistiva f\u00f6rluster som kan uppst\u00e5 som v\u00e4rme och p\u00e5verka den maximala drifttemperaturen och antennens returf\u00f6rlust\/VSWR.<\/p>\n\n\n\n

Utbredningshastighet:<\/strong> I fri luft f\u00e4rdas en elektromagnetisk v\u00e5g med ljusets hastighet; men i en koaxialkabel minskar de kapacitiva och induktiva egenskaperna, skin-effekten och dielektriska f\u00f6rluster hastigheten som signalerna fortplantar sig med. Hastighet p\u00e5verkar fasen av s\u00e4nda och mottagna signaler, vilket kan vara kritiskt med flera antenner.<\/p>\n\n\n\n

Exempel p\u00e5 RF-koaxialkabel<\/h2>\n\n\n\n

Flera RF-koax-standarder har utvecklats under \u00e5ren, den mest etablerade \u00e4r RG-systemet. Exemplen inkluderar RG58, RG59 och RG174.<\/p>\n\n\n\n

RG58<\/strong> – denna 50 Ohm koaxialkabel fr\u00e5n Bedea <\/a>– se bild 1 – har en ytterdiameter p\u00e5 5.0 mm, kopparfl\u00e4tad sk\u00e4rm och en hastighetsfaktor p\u00e5 0.66. D\u00e4mpningen per 100 m vid 100 MHz \u00e4r 15.2 dB och stiger till 34.4 dB\/100 m vid 500 MHz. Ur ett mekaniskt perspektiv \u00e4r den minsta b\u00f6jradien 25 mm och vikten 36 kg\/km.<\/p>\n\n\n\n

RG59<\/strong> – ett exempel p\u00e5 en 75 Ohm impedans koaxialkabel \u00e4r RG 59 Flex<\/a> fr\u00e5n Tasker<\/a>. Med en ytterdiameter p\u00e5 6.1 mm och en maximal sp\u00e4nning p\u00e5 2 000 V. D\u00e4mpningsegenskaperna \u00e4r 15.7 dB\/100m vid 200 MHz och 33.6 dB\/100m vid 800 MHz.<\/p>\n\n\n\n

RG174<\/strong> (LMR-100A) – diametern p\u00e5 denna RG174<\/a> koaxialkabel fr\u00e5n Bedea<\/a> m\u00e4ter 2.8 mm, impedans 50 Ohm och maximal sp\u00e4nning 1100 V. Vid 200 MHz \u00e4r d\u00e4mpningen 41.5 dB\/100m och 68 dB\/100m vid 500 MHz.<\/p>\n\n\n\n

RF-kontaktdon<\/h2>\n\n\n\n

RF-kontakdon kan i stora drag delas in i tv\u00e5 kategorier. S\u00e5dana som \u00e4r l\u00e4mpliga f\u00f6r montering externt p\u00e5 utrustning och de f\u00f6r anv\u00e4ndning inuti en kapsling. Majoriteten av kontakter som anv\u00e4nds f\u00f6r sammankoppling tenderar att rymma tjockare koaxialkablar, ge en viss dragavlastning och tillhandah\u00e5ller vanligtvis ett s\u00e4tt att l\u00e5sa ihop hona och hane. Dessa kontakter inkluderar N-typ, TNC<\/a>, BNC<\/a>, UHF(PL259)<\/a>, SMA och RPSMA <\/a>(SMA med omv\u00e4nd polaritet).<\/p>\n\n\n\n

RF-kontakter anv\u00e4nds ocks\u00e5 f\u00f6r att f\u00e4sta antenner internt, till exempel fr\u00e5n en tr\u00e5dl\u00f6s modul till en internt f\u00e4st antenn, inklusive u.Fl-serien fr\u00e5n Hirose och MHF-serien fr\u00e5n IPEX. B\u00e4gge serierna har en viss grad av korskompatibilitet.<\/p>\n\n\n\n

Liksom de flesta kontaktdon \u00e4r de specificerade efter k\u00f6n och passar vanligtvis ett begr\u00e4nsat antal koaxialkabeltyper. De flesta kontakter angivna h\u00e4r har maximal arbetsfrekvens upp till tiotals GHz. Vid val av kontakter, kontrollera \u00e4ven returf\u00f6rlustegenskaperna och effekthanteringsf\u00f6rm\u00e5gan.<\/p>\n\n\n\n

Den har ett m\u00e4ssingshus med diameter 7.9 mm med en teflonisolator och ett guldpl\u00e4terat mittstift. Kabeltypen som st\u00f6ds \u00e4r RG-174. En serie med omv\u00e4nt k\u00f6n (RPSMA) finns ocks\u00e5.<\/p>\n\n\n\n
