Resistor ya RF ni iki?

Resistor ya RF ni iki? Mu magambo make, resistor zikoreshwa muri sisitemu y'itumanaho ya RF mikorobe zitwa resistor za RF.
Buri wese agomba kumenya neza umuvuduko w'amashanyarazi wa radiyo, ari na yo mvugo ngufi ivuga ku miraba ya electromagnetic ihindagurika cyane.
Umuyoboro w'amashanyarazi uhinduka inshuro zirenga 10000 ku isegonda witwa umuyoboro w'amashanyarazi ukoresha radiyo.
Resistor ya RF ni igikoresho kidakora gishobora kubuza umuvuduko w'amashanyarazi wa radiyo kwinjira. Kandi kigahindura ingufu z'amashanyarazi mo ubushyuhe cyangwa ubundi bwoko bw'ingufu, hamwe n'igice cya ohms (Ω) kimwe n'ubudahangarwa busanzwe.

Ibirwanya RF muri rusange bishyirwa mu byiciro hashingiwe ku mbaraga, kandi hari uburyo butandukanye bwo kubishyira mu byiciro:

Ishyizwe mu byiciro hakurikijwe imiterere yo hanze, ishobora kugabanywamo:

1. Uturinda twa Chip (uturinda twa chip tugabanyijemo uturinda twa electrode imwe na turinda twa electrode ebyiri)

2. Resistor ifite lead (resistor ifite lead zigabanyijemo resistor imwe ifite lead n'iy ...

3. Umurwanya w'urukiramende (imirwanyamubiri igabanyijemo imirwanyamubiri imwe n'imirwanyamubiri ibiri)

 

Dukurikije uburyo ibikorwa byo gukora bishyirwa mu byiciro, bishobora kugabanywamo:

1. Umurwanya w'urumuri rwinshi (witwa umurwanya w'urumuri rwinshi)

2. Umurwanya w'urumuri rw'urumuri rworoheje (witwa umurwanya w'urumuri rw'urumuri rworoheje)

 

Dukurikije ishyirwa mu byiciro ry'ingufu, ishobora kugabanywamo:

1. Ingufu nyinshi zo kurwanya RF (zitwa resistor ifite imbaraga nyinshi, muri rusange yerekeza ku ingufu zifite imbaraga za 60W cyangwa zirenga)

2. Resistor ya RF ifite imbaraga nke (mu magambo ahinnye nka resistor ifite imbaraga nke, muri rusange yerekeza ku resistor ifite imbaraga ziri munsi ya 20W)

 

Ishyizwe mu byiciro hakurikijwe inshuro, ishobora kugabanywamo:

1. Resistor ya RF ifite frequency nyinshi (izwi nka resistor ifite frequency nyinshi, muri rusange resistor ifite frequency iri hejuru ya 3GHz)

2. Resistor ya RF ifite frequency nkeya (mu magambo ahinnye nka resistor ifite frequency nkeya, muri rusange resistor ifite frequency iri munsi ya 3GHz)

 

Ibikoresho n'ibyiza n'ibibi byo gukora resistor za RF:

1. Oxyde ya Beriliyumu (BeO) ifite ubushobozi bwo gutwara ubushyuhe bwinshi, hafi ya buri kimwe n'umuringa n'aluminium, ifite ubushobozi bwo gutwara ubushyuhe bwa 200-250W (mK), bigatuma iba ibikoresho bikunzwe cyane mu gukora resistor za RF. Ingorane yayo ikomeye ni uko ifite uburozi bwinshi mu buryo bw'ifu, bigatuma bigorana ko ibikomere bikoranaho bikira. Muri rusange rero, abakora resistor za RF bagura ibikoresho byabumbwe kandi ntibakenera gutunganya ubwa kabiri. Ibi bituma ikoreshwa rya beriliyumu (BeO) mu gukora resistor za RF zishobora gucapwa gusa kuri chip imwe, bigabanya cyane umusaruro.

2. Aluminium nitride (AlN) nayo ni ibikoresho bifite ubushyuhe bwinshi, bifite ubushyuhe bungana na 20W/mK. Ifite imiterere myiza ya mekanike kandi ifite imbaraga zo kuzunguruka kurusha aluminium oxyde na beryllium oxide ceramics. Bitewe n'uko idahumanya, ishobora gucapwa hakoreshejwe ikoranabuhanga ryo gucapa rihoraho, rishobora kunoza cyane umusaruro. Kuri ubu, ni byo bikoresho bikunzwe cyane ku bikoresho birwanya ubushyuhe bwinshi.

3. Okiside ya aluminiyumu (Al2O3) ni yo ikundwa cyane mu gukingira ubushyuhe bukoresha ingufu nke, kuko ubushyuhe bwayo bungana na 1/5 cya nitride ya aluminiyumu. Ntikunze gukoreshwa mu guhitamo ibikoresho bya resistor za RF zifite imbaraga nyinshi.

 

RFTYTTechnology Co., Ltd. ni uruganda rw’umwuga rukora ibikoresho bidakoresha imbaraga nka resistor za RF, RF attenuators, coaxial loads, coaxial attenuators, adjustable attenuators, RF isolators, RF circulators, nibindi.
Ibicuruzwa byayo bikoreshwa cyane muri sisitemu nka radar, ibikoresho, navigation, itumanaho rya mikoroonde rikoresha imiyoboro myinshi, ikoranabuhanga ryo mu kirere, itumanaho rigendanwa, kohereza amashusho, na mikoroonde integrated circuits.
Kuva yashingwa, kugira ngo irusheho gukorera abakiriya no kugirira akamaro sosiyete, iyi sosiyete yibanze ku ikoranabuhanga inateza imbere imiyoboro mito y’amashanyarazi itandukanya ibicuruzwa n’ibicuruzwa (microstrip isolators/circulators) ubu iri ku rwego rumwe n’amahame mpuzamahanga. Ibintu bidasanzwe bigize iyi sosiyete ni ubugari, ubunini buto, n’uburemere bworoheje.
Kandi ifite ibyiza byo kuba ikora neza kandi ihendutse, bigatuma ikoreshwa cyane mu miyoboro ya microwave. Hamwe n'iterambere ryihuse rya sisitemu za microwave nka radar yashyizwe ku rwego rwo hejuru, amahirwe yo kuzikoresha azarushaho kuba meza.
Isosiyete izibanda ku guhaza ibyifuzo by'abakiriya bayo, iharanira gushyiraho imiterere yihariye no gukomeza kunoza ireme ry'ibicuruzwa, ubwoko bwabyo, na serivisi. Guha abakiriya icyubahiro, kubakoresha amarangamutima yacu, no kwihesha izina ry'ukuri kwacu.
Twagize icyizere ku bakiriya bacu dukoresheje ikoranabuhanga rihanitse, ireme ryinshi, na serivisi nziza, tugera ku nyungu rusange kandi tugaha igihugu ibidukikije bihamye kugira ngo habeho umuryango urangwa n'ubwumvikane.
