Injiza gusubira gutakaza mu guhitamwo umuhinduzi wa RF

A Rf Ihindura input return loss akenshi itoranywa mu gihe c’umugambi, ariko ishobora gufata ingingo nimba iradiyo, igice c’itumanaho canke urubaho rwo gupima bishobora gutunganirizwa ata gusubira guhingura. Mu guhindura ama connectors, RF test ports n’ibipande bigenzurwa n’impedansi, iki gice si ikintu co mu murongo gusa kiri mu gitabu c’ibikoresho. Ni igice c’inzira y’ikimenyetso, igice c’umugambi w’impedansi kandi, mu bicuruzwa vyinshi, igice c’impamvu urubaho rumwe rwitwararika kurusha urundi mu gihe co kwemeza. Paje y’ibicuruzwa ngirakamaro rero ikwiye gufasha abahinga kugereranya inyifato y’amashanyarazi ishobora gupimwa, atari amazina y’ibicuruzwa gusa canke ivyo abaguzi bavuga.

Iciyumviro ca mbere co guhitamwo ni igikorwa c’igice. Bivanye n’imiterere, ibihimba vy’umuhinduzi wa RF bishobora gukoreshwa mu kugabanya inguvu zigaragara ku ntumbero aho umuhinduzi ahurira n’inkomoko, umuhuza canke uruja n’uruza rwo hejuru. Uwo murimo utegerezwa gutomoka imbere y’uko ikiganiro c’inomero y’igice gitangura. Igihindura 1:1 RF, igihindura 1:4. Impedansi ihindura, umuhinduzi w’amajwi y’amajwi y’ama ohm 50 n’umuhinduzi w’amajwi y’amajwi y’amajwi y’amajwi ya balun y’umurongo wagutse vyose birashobora kuboneka mu bikoresho bisa n’ivyo vy’amajwi y’amajwi, ariko bitorera umuti ingorane zitandukanye. Iyo uruhara rusobanuwe, akayunguruzo gakurikira ni idirisha ry’umuyagankuba: Injiza RL, Zo(ohm), gutangura urubaho, urutonde rw’incuro n’ugushiramwo amapaki. Ivyo bipimo bibwira injeniyeri nimba umuntu ari ku rutonde rwa mbere rw’abatowe canke akwiye gukurwaho imbere y’uko asabwa ivyerekanwa.

Imbonerahamwe z’ibicuruzwa vya EASTEVER zikwiye gutuma izo ngingo zoroha mu kwerekana Zo(ohm), igipimo c’impedansi, Igipapuro, Min(MHz), Max(MHz), IL, Intambwe, Amp n’Injiza RL. Zo(ohm) n’igipimo c’impedansi bidondora ibidukikije bikoreshwa n’intumbero yo guhindura. Min(MHz) na Max(MHz) vyerekana nimba igice gipfutse umurongo w’ibikorwa nyawo aho gupfuka ahantu heza ho hagati. IL, canke gutakaza ivyo kwinjiza, birinda ingengo y’imari y’ikimenyetso. Phase na Amp balance birahambaye igihe cose circuit ikoresha ports za RF ziringaniye, ama receveurs y’itandukaniro canke uguhindura balun. Input RL ifasha injeniyeri guca urubanza ku ruhande rw’inkomoko, ivyo bikaba bihambaye cane cane hafi y’ibifatanya, amayunguruzo, ama switch ya RF n’ibibanza vya IC.

Iyo umuhinduzi yicaye iruhande y’igifatanya, igisubizo gipimwa ni uguhuza igice, amapadi, amavia yo hasi n’ubuhinga bwo gutangura. Injiza RL ikwiye gusuzumwa ku ntumbero itegekanijwe. Mu bikoresho vy’ukuri, uruzitiro rukikuje akenshi rurahindura igisubizo kuruta uko umuntu yari yiteze. Igihindura canke igice c’umuyagankuba kibona ubushobozi bw’ivyuma, ugusubira hasi, ubuhinga bwo gutera, ingabo ziri hafi, gutangura kw’ivyuma bifatanya n’ibindi rimwe na rimwe n’uruzitiro rw’igicuruzwa ca nyuma. Kubera iyo mpamvu, agaciro k’urutonde gakwiye gufatwa nk’intango y’isuzuma ry’ubuhinga. Ingingo ya nyuma ikwiye gushingira ku gupima mu gipande c’intumbero, n’ivyo nyene bifatanya, uruzitiro, umugozi n’ivyo igicuruzwa kizokoresha mu guhingura.

Ivyitegererezo vy’ishingiro nka TC1-1-13M+, TCD-13-4-75+ na DBTC-10-13LX+ ni ngirakamaro mu guhanahana amakuru hagati y’ubuhinga n’ugutanga amasoko kuko bidondora ubwoko bw’igikorwa buzwi. Bashobora kandi gufasha uwuguze gusigura igituma umugambi ukeneye gushirwa hejuru . Rf Ihindura, a 50 ohm Rf Ihindura, umuhinduzi w’umurongo wagutse canke balun ifise urutonde rw’incuro runaka. Ariko rero, ikigereranyo c’ishingiro ntigikwiye gushikirizwa nk’ikintu gisubirira ata guca ku ruhande. Ni vyiza gusobanura ibice vya EASTEVER nk’ubundi buryo bwo gusuzuma. Ivyo bigereranywa bikwiye gushiramwo urutonde rw’incuro, igipimo c’impedansi, ukubura kw’injiza, uburinganire bw’inzira n’uburemere, ukubura kw’ugusubira inyuma, umuzigo, ikirenge n’ukuboneka.

IC context na yo irafasha gutuma uguhitamwo kuba gutomoye. Ivyuma bikoresha ADF4351, AD9361 n’iminyororo y’ibimenyetso vya RF akenshi birafise ivyo vyitezwe vy’impedansi, imiterere y’ibimenyetso canke ingero z’ivyuma vy’isuzuma, ariko igice kidakora gica gitegerezwa kujana n’igicuruzwa nyaco. Igishushanyo c’ishingiro gishobora gukoresha balun, choke canke transformateur kubera ko urubaho rw’isuzuma rwari rufise umurongo, umuhuza n’uruzitiro rw’ibintu. Iyo iyo IC nyene yimuriwe muri radiyo ifatwa mu minwe, mu rubaho rwo guhanahana amakuru, mu ikarita yo gufata amakuru canke mu muryango w’ivyuma bitagira umurongo, uguhitamwo kw’ibidakora kwoshobora gukenera guhinduka.

Ku ba injeniyeri ba RF n’imigwi y’abagerageza bagereranya ibice vy’ibikoresho bigenzurwa, agaciro k’urupapuro rw’urutonde rwanditswe neza ni umuvuduko n’ukwizigira. Iryo paji rikwiye kwemerera umusomyi guhitamwo imbere y’uko yohereza ikibazo. Ivyo bishobora kandi guha amasoko ururimi ruhagije kugira ngo umuntu abaze ikibazo kibereye: impedance ikenewe, umurongo w’ibikorwa, umupaka w’amapaki, intumbero yo gutakaza, uburinganire busabwa, icizigiro co gutakaza n’uko igice kiriko kirakoreshwa mu guhingura umugambi mushasha canke mu gusubiramwo inkomoko y’ubundi buryo. Ivyo bigabanya amahirwe y’uko umuguzi asaba gusa inomero y’igice mu gihe injeniyeri agikeneye ko ivyiyumviro vy’amashanyarazi bisuzumwa.

Ikosa ry’uguhitamwo risanzwe ni ugufata ugutakaza ivy’ugusubira inyuma nk’ivyiyumviro vy’inyuma vy’urutonde naho kenshi bifata ingingo y’ingene ikimenyetso kigaragara ku ntebe. Ni co gituma iyo page idakwiye gusezerana birenze urugero. RF passive n’ibihimba vy’umuyagankuba birashikirwa cane n’imiterere n’imiterere y’imirongo. Ikete ry’uguhitamwo rifise inshingano ribwira umusomyi ico igice gishobora gufasha gutorera umuti, amakuru akwiye kugereranywa n’igituma igerageza ryo ku rwego rw’inama nkuru rikiri ngombwa. Iryo jwi rirashobora kwizigirwa cane ku ba injeniyeri kuruta ivyo abantu benshi bavuga ku bijanye n’uguhuza kw’ibintu vyose.

Ivyiza Rf Ihindura input return loss page ikwiye kuyobora umusomyi kuva ku gukenera gukoresha gushika ku kugereranya gupimwa. Tangana n’igikorwa, ushiremwo Zo(ohm) n’igipimo, wemeze Min(MHz) na Max(MHz), ugereranye IL, Phase, Amp na Input RL, hanyuma usuzume ko umuzigo n’imiterere bihuye. Inyuma y’ivyo, nusabe ivyitegererezo maze ubishire mu ngiro ku rubaho nyarwo. Iyi nzira ifasha abahinga ba RF, abahinga b’ibikoresho, abahinga b’amasoko n’abahinga b’ibice bindi kuko ihuza urutonde rw’ibicuruzwa n’ingingo bafata vy’ukuri.
