Amakuru

Hari ubwoko bubiri bw'ibanze bwa duplexers: Band Pass na Band Reject.

Antene isanzwe ifite duplexer

Akamaro gagaragara ko gukoresha duplexer ni uko dushobora kohereza no kwakira antene imwe gusa. Kubera ko dufite umwanya uri ku minara ku biro by'ibanze ku giciro gito, iyi ni inyungu nyayo.

Muri sisitemu imwe y’umuyoboro, aho hari umuyoboro umwe gusa n’umukiriya umwe, gukoresha duplexer kugira ngo bashobore gusangira antene imwe ni amahitamo yoroshye. Ariko, iyo hatekerejwe ku miyoboro myinshi irimo imiyoboro myinshi ihuriweho yo kohereza no kwakira, ibintu birushaho kuba ingorabahizi.

Ingorane nyamukuru yo gukoresha duplexers muri sisitemu nyinshi z'itumanaho irashobora kugaragara iyo dutekereje ku buryo bwo guhinduranya amakuru. Uku ni uruvange rw'ibimenyetso byinshi byo kohereza amakuru kuri antene.

Antene za Tx na Rx zitandukanye

Iyo dukoresheje antene zitandukanye zo kohereza no kwakira, bifata umwanya munini ku munara.

Inyungu ikomeye ni uko, nubwo uburyo bwo gukwirakwiza amakuru bukomeje kuba kimwe hagati y’ibimenyetso byoherejwe hamwe, nta nzira igororotse ibi bicuruzwa bikigeramo.

icyuma gifata amashusho. Ahubwo, kwitandukanya hagati y’antene zohereza amakuru n’izikira bitanga uburinzi bwinyongera. Niba icyuma gifata amashusho n’izikira amakuru biteguye mu buryo bugororotse (ni ukuvuga: kimwe kiri hejuru y’ikindi, muri rusange antene yo kwakira iri hejuru y’umunara), ubwo kwitandukanya birenga 50dB biroroshye kugerwaho.

Mu gusoza rero, kuri sisitemu imwe y'imiyoboro, komeza ukoreshe duplexer. Ariko kuri sisitemu zifite imiyoboro myinshi, nubwo antene zitandukanye zizagutwara umwanya munini kuri buri munara, iyi ni yo nzira ikomeye. Irinda sisitemu yawe neza kubangamira gukomeye guturuka ku miyoboro idakora bitewe n'udukosa duto cyane kandi bigoye gutandukanya ibyuma cyangwa ibikoresho byo kubungabunga.

UHF DuplexerUmushinga

Impamvu nyamukuru hano ni ukurinda ishyirwaho ry'insinga mu rugo.

Ubwo yubatswega, inzu yanjye yashyizwemo insinga imwe ya coaxial drop down iva mu cyumba cyo hejuru ijya mu cyumba cyo kuruhuka, ihishe neza mu rukuta rwo mu gisenge. Iyi nsinga itwara imiyoboro ya televiziyo ya DVB kuva kuri antene yo hejuru ijya kuri televiziyo yo mu cyumba cyo kuruhuka. Mfite kandi agasanduku ka televiziyo ya cable muri icyo cyumba cyo kuruhuka nifuza ko gakwirakwizwa hirya no hino mu nzu kandi amplifiers zishyirwa neza muri icyo cyumba kugira ngo byoroshye kugera mu byumba byose. Kubwibyo, Duplexer iri ku mpera zombi z'insinga ya drop down izayifasha gutwara DVB-TV ku gice cyo hejuru na Cable-TV ku gice cyo hejuru icyarimwe, mu gihe nahisemo Frequency ikwiye yo gukwirakwiza Cable-TV.

Televiziyo nyinshi zitangirira kuri 739MHz zikagera kuri 800MHz. Ikwirakwizwa rya Cable-TV rishobora gukorwa kuva kuri 471-860 MHz. Bityo nzashyira mu bikorwa igice cyo gutwara CableTV hejuru kuri ~488MHz n'igice cyo gutwara DVB-TV hasi. Igice cyo gutwara hasi kizanatwara DC kugira ngo gishyire ingufu kuri amplifiya yo gutwara mu cyumba cyo hejuru na kode za remote za Magic-eye zisubira mu gasanduku ka Cable-TV.
