Intsinga za RF, nk’uburyo nyamukuru bwo gutanga ikimenyetso c’incuro nyinshi-, zifise uruhara rudashobora gusubirizwa mu guhanahana amakuru, mu vy’indege, mu gutangaza amakuru, no mu kugerageza no gupima. Ibirango vyavyo vy’ubuhinga biragira ico bikoze ku butungane bw’ikimenyetso, ku kwizigirwa kw’urutonde, no ku guhuza n’ibikorwa vy’ubuhinga. Iki kiganiro kirasigura mu buryo butunganye ibiranga ubuhinga nyamukuru vy’imirongo ya RF bivanye n’ubushobozi bw’umuyagankuba, imiterere y’ubuhinga, ubushobozi bwo guhindura ibidukikije, n’ibintu bisanzwe vyo gukoresha.
I. Ibikorwa vyiza cane vy’umuyagankuba: Gutakaza bike n’ugushikama kwinshi
Ivyerekeye ubuhinga bwa mbere bw’imirongo ya RF ni ubushobozi bwayo bwo gutanga ikimenyetso ku mirongo myinshi. Gutakaza bike ni kimwe mu vyiza vyabo nyamukuru. Mu gutuma ibikoresho vy’umuyagankuba bigenda neza (nk’umuringa udafise umwuka w’ikirere canke umuringa w’ifeza), ivyuma bizibira umuriro (nk’ivyuma bita polytetrafluoroethylene (PTFE) canke polyethylene ikomeye), be n’uguhingura imiterere y’ivyuma, ugucika intege kw’ibimenyetso vy’incuro nyinshi gushika kuri GHz birashobora kuba (typ ingero ziri hasi cane. Nk’akarorero, intsinga zikomeye zishobora gushika ku gutakaza 0,5 dB/meter mu murongo wa 18 GHz.
Ihuza ry’impedansi y’ibiranga ni ikindi kintu nyamukuru, gifise agaciro kagereranywa harimwo 50Ω (ikoreshwa mu gutanga ubushobozi no mu buryo bwo kugerageza) na 75Ω (isanzwe mu gutangaza amakuru no kuri televiziyo). Ivyiyumviro vy’ubushobozi bwo kwihanganira (nk’akarorero, ±1%) birabuza neza ivyerekanwa vy’ikimenyetso kandi bikaba bituma ubushobozi bugenda neza. Ikindi, ubushobozi bwo gukingira bushikwako biciye ku nzira nyinshi z’urusenga (nk’umuringa canke ifeza) canke ibikoresho vy’ivyuma vy’aluminium, bifise ubushobozi bwo gukingira burengeye -90dB, bugahagarika neza ububabare bw’umuyagankuba (RFMIakage) n’ububabare bw’umuyagankuba (RFMIakage).
II. Ugukora neza mu vy'ubuhinga: Guhuza Uguhinduranya n'Ugukomera
Igishushanyo c’ubuhinga c’imirongo ya RF kigomba guhuza ibisabwa vyo gutanga ikimenyetso n’ivyo gushiramwo. Hashingiwe ku bisabwa vyo guhinduranya, bishobora gushirwa mu migwi y’imirongo ikomeye (ikoresha umurongo w’inyuma w’umuringa ukomeye ugumya igipimo gikomeye inyuma yo gupfukama), imirongo y’inyuma ishobora guhinduka (ikoresheje umurongo w’inyuma ushobora guhinduka ufise intsinga nyinshi z’umuringa zishobora gukoreshwa kugira ngo ushike ku umuyoboro w’ibikomere ubereye kwinyiganza kenshi).
Guhitamwo uburyo bwo gukingira umuriro biragira ingaruka zitaziguye ku mico y’umubiri w’umugozi. Nk’akarorero, PTFE, n’ubushobozi bwayo bwo gukuraho umuriro buke cane (nk’ibice 2,1) n’ibiranga ubushuhe buhoraho (-55℃gushika kuri +260℃), irabereye gukoreshwa mu bidukikije bikomeye cane. Ku rundi ruhande, polyethylene yagutse iragabanya ugucika intege kw’ikimenyetso mu kugabanya uburemere bw’umuyagankuba mu gihe iguma ifise uburemere buke. Ibikoresho vyo hanze vy’igipfukisho (nk’ivyo bita polyvinyl chlorure (PVC), polyuréthane (TPU) canke ivyuma bita fluoropolymères) biratuma kandi umuntu adashobora gusenyuka, amavuta canke ngo akoreshe ibihe.
III. Igishushanyo ciza co guhindura ibidukikije
Intsinga za RF z’inganda n’iz’igisirikare zitegerezwa guhangana n’ingorane zikomeye z’ibidukikije. Ugushikama kw’ubushuhe gushikwako mu guhitamwo ibikoresho vy’ugukingira ubushuhe bwinshi- (nk’ivya FEP canke PTFE vyuzuye ivyuma-vyuzuye ivyuma). Ibintu bimwe bimwe bishobora kuguma bikora kuva kuri -70 gushika kuri +400 . Uguhangana n’ubukonje n’ugusenyuka bishingiye ku mibumbe y’ugukingira kw’igipfukisho (nk’igipande c’aluminium + igipfukisho c’ivyuma bishushe) canke ivyuma bidasanzwe (nk’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma) kugira ngo ubukonje ntibuze bwinjire mu gipfukisho n’ugusenyuka kw’ivyuma vy’ivyuma.
Kugira ngo umuntu akingirwe imibabaro y’ubuhinga, intsinga zikingira ibirwanisho zituma zikomera cane mu gukomera no gukomera hakoreshejwe ivyuma bitagira ibara canke umugozi w’icuma, bikaba bituma zishobora gushirwa munsi y’ubutaka canke zikoreshwa mu modoka. Ikindi, ibikoresho vyo gupfuka umwotsi muto -halogen (LSZH) bihuye n’ibisabwa vyo gukingira umuriro mu bijanye n’uguca mu nzira y’amagariyamoshi no mu bikorwa vyo mu kiyaga.
IV. Ibikoresho bisanzwe n'Ingingo z'Ihitamwo
Ibirango vy'ubuhinga vy'imirongo ya RF nivyo bigena ingene zikoreshwa:
Ivyuma vy’itumanaho n’uburyo bwa radar: Intsinga zikomeye zifise ubushobozi buke bwo gutakaza n’ubushobozi bwinshi (nk’urutonde rwa LMR) ni zo zikundwa kugira ngo ibimenyetso vy’imipfunda y’imirongo y’imirongo y’imirongo y’imirongo (nk’umurongo wa 28 GHz 5G) bishobore gushikama.
Laboratwari n’igerageza n’ingero: Intsinga zishobora guhinduka zifise ubuhinga bwinshi (nk’iza RG-316) zikoreshwa mu gupima ibikoresho nk’ibikoresho bipima urusobe rw’ibintu (VNAs) kubera inyishu yazo y’inzira idahinduka.
Satellite n’ivy’ikirere: Intsinga z’uburemere burengeye ubw’ibindi (nk’ibikoresho bifise uburemere buke cane) zifatanijwe n’ibikoresho bishobora guhangana n’imishwarara-bihuye n’ibisabwa mu bidukikije vy’ikirere bikomeye cane.
Igihe uhitamwo umugozi, nuzirikane urugero rw’incuro, ubushobozi bw’ububasha, uburebure bw’ugupfukama, n’ibiciro. Nk’akarorero, ibikorwa vy’incuro nyinshi-bisaba kwitwararika igipimo c’umuvuduko w’umuriro (VSWR), mu gihe ibikorwa vy’inguvu nyinshi bisaba uburebure bw’umurongo w’umuyagankuba n’uguhingura ubushuhe.
Iterambere ry’ubuhinga mu nsinga za RF rirabandanya gutuma habaho iterambere ry’ubuhinga bwa none bukoresha incuro nyinshi-. Kuva ku buhinga bw’ibikoresho (nk’ibipande vy’ivyuma vy’ivyuma) gushika ku buhinga bushasha bw’imibumbe (nk’imiterere y’ivyuma bishobora kuramburwa), imipaka y’ubushobozi bwavyo iraguma isunikwa. Mu gihe kizoza, n’iterambere ry’itumanaho rya 6G, ubuhinga bwa terahertz, n’ubuhinga bw’amakuru y’ubuhinga bwa quantum, intsinga za RF zizorushiriza gutera imbere zija ku rwego rwo hejuru -wideband, ultra-low loss, n’ubushobozi bw’ubwenge, zibe ikiraro nyamukuru gihuza isi y’umubiri n’iy’ubuhinga bwa none.
