75 Ohms Joojinta Rarka Microwave-ka RF
Joojinta 75 ohm
Culayska 75 ohm waa Joojinta iska caabbinta ee caadiga ah oo inta badan loo isticmaalo tijaabinta iyo cabbiraadda qalabka sida matoorada calaamadaha, amplifiers-ka korontada, nidaamyada RF, telefishannada, iwm. wareegyada.
Joojinta Microwave-ka waxay leedahay sifooyinka soo socda:
1. Joojinta 75 ohm waxay yareysaa milicsiga calaamadaha iyo lumitaanka, waxay wanaajisaa gudbinta calaamadaha, sidaas darteedna waxay wanaajisaa xasilloonida nidaamka iyo isku halaynta.
2. Joojinta RF waa caqabad joojin heer sare ah oo si weyn looga isticmaalo warshadaha isgaarsiinta, taasoo buuxisa heerarka Shaybaarka Isgaarsiinta Federaalka (NIST) waana mid si fudud loogu isticmaali karo shaqada dhabta ah.
3. Inta lagu jiro habka cabbirka iyo tijaabinta, 75 ohm Joojinta waxay ka ilaalin kartaa qalabka isha waxyeello ka soo gaarta danabka xad-dhaafka ah ama korontada xad-dhaafka ah, iyadoo hubinaysa badbaadada qalabka tijaabada iyo qalabka la tijaabiyay.
4. Joojinta 75 ohm waxay taageeri kartaa soo saarista korontada sare waxaana lagu dabaqi karaa nidaamyada RF ee u baahan awood sare.
5. Joojinta 75 ohm waxay bixin kartaa iska caabinta joojinta oo sax ah si loo cabbiro sax ah oo ku saabsan xuduudaha astaamaha wareegga, taasoo ka dhigaysa natiijooyinka baaritaanka kuwo sax ah oo la isku halleyn karo.
Waxay leedahay shaqooyinka soo socda:
1. Joojinta 75 ohm waxaa loo isticmaali karaa in lagu tijaabiyo awoodda wax soo saarka, astaamaha jawaabta soo noqnoqoshada, iyo in la xaqiijiyo waxqabadka guud ee wareegga.
2. Joojinta 75 ohm waxaa loo isticmaali karaa in lagu waafajiyo is-hortaagga hirarka, lagu yareeyo milicsiga calaamadaha iyo khasaaraha, lagu wanaajiyo gudbinta calaamadaha, iyo in la hagaajiyo xasilloonida nidaamka iyo isku halaynta.
3. Joojinta 75 ohm waxay u adeegi kartaa dekedda wax soo saarka calaamadaha ee matoorada calaamadaha iyo qalabka kor u qaada korontada, taasoo awood u siinaysa calaamadaha in loo soo saaro qaybaha kale ee nidaamka si loogu sameeyo tijaabin iyo cabbiraad.
4. Joojinta 75 ohm waxay ka ilaalin kartaa qaybaha kale ee wareegga inay ka fogaadaan danab xad dhaaf ah iyo in ka badan Joojinta, taasoo yaraynaysa khatarta dhaawaca qalabka iyo cilladaha.
QualwaveWaxay bixisaa saxnaan sare iyo awood sare oo kala duwan oo ah 75 Ohms Joojinno waxay daboolaan inta jeer ee DC ~ 3GHz. Joojinta waxay leedahay nooc kala duwan si loo daboolo baahiyaha macaamiisha.
