Ihuza ryerekezo ni microwave isanzwe / milimetero yibice bigize ibipimo bya microwave hamwe nubundi buryo bwa microwave.Birashobora gukoreshwa mugutandukanya ibimenyetso, gutandukana, no kuvanga, nko kugenzura ingufu, gusohora ingufu zituruka kumashanyarazi, ibimenyetso bitandukanya ibimenyetso, kwanduza no kugaragariza inshuro nyinshi Ikizamini, nibindi. muri kijyambere ya swpt-inshuro zigaragaza.Mubisanzwe, hari ubwoko bwinshi, nka waveguide, umurongo wa coaxial, umurongo, na microstrip.
Igishushanyo 1 nigishushanyo mbonera cyimiterere.Harimo cyane cyane ibice bibiri, umurongo nyamukuru hamwe numurongo wabafasha, uhujwe nundi muburyo butandukanye bwimyobo mito, ibice, nibyuho.Kubwibyo, igice cyimbaraga zinjiza kuva "1 ″ kumurongo wanyuma uzahuzwa kumurongo wa kabiri.Bitewe no kwivanga cyangwa kurenga imiraba, imbaraga zizajya zihererekanwa gusa kumurongo wa kabiri-icyerekezo kimwe (bita "imbere"), naho ubundi Ntabwo hafi yo gukwirakwiza amashanyarazi muburyo bumwe (bita "revers")
Igishushanyo cya 2 ni icyerekezo cyambukiranya icyerekezo, kimwe mu byambu biri muri kupler gihujwe nubatswe-bwuzuye umutwaro.
Gushyira mu bikorwa icyerekezo
1, kuri sisitemu ya synthesis
Icyerekezo cya 3dB cyerekezo (gikunze kwitwa ikiraro cya 3dB) gikunze gukoreshwa muri sisitemu yo gutwara ibintu byinshi, nkuko bigaragara mumashusho hepfo.Ubu bwoko bwumuzingi burasanzwe muri sisitemu yagabanijwe murugo.Nyuma yuko ibimenyetso f1 na f2 biva mubyuma bibiri byongera imbaraga zinyuze muri 3dB icyerekezo, icyerekezo cya buri muyoboro kirimo ibice bibiri bya f1 na f2, kandi 3dB igabanya amplitude ya buri kintu kigize.Niba imwe mubisohoka byahujwe nu mutwaro ukurura, ibindi bisohoka birashobora gukoreshwa nkimbaraga zimbaraga za pasiporo intermodulation yo gupima.Niba ukeneye kunoza ubwigunge kurushaho, urashobora kongeramo ibice nka filteri hamwe na wenyine.Gutandukanya ikiraro cyateguwe neza 3dB kirashobora kurenga 33dB.
Icyerekezo gihuza gikoreshwa mumbaraga zihuza sisitemu imwe.
Icyerekezo cya gully nkubundi buryo bwo gukoresha imbaraga bwerekanwe mubishusho (a) hepfo.Muri uyu muzunguruko, icyerekezo cyo guhuza icyerekezo cyashyizwe mubikorwa.Dufashe ko impamyabumenyi yo guhuza ibice byombi ari 10dB kandi icyerekezo ni 25dB, kwigunga hagati ya f1 na f2 ni 45dB.Niba inyongeramusaruro ya f1 na f2 zombi ari 0dBm, ibisohoka byose hamwe -10dBm.Ugereranije na couple ya Wilkinson mumashusho (b) hepfo (agaciro kayo ko kwigunga ni 20dB), ikimenyetso kimwe cyo kwinjiza OdBm, nyuma ya synthesis, hariho -3dBm (utitaye ku gihombo cyo gushiramo).Ugereranije na inter-sample imiterere, twongera ibimenyetso byinjira mubishusho (a) na 7dB kugirango ibisohoka bihure nigishushanyo (b).Muri iki gihe, kwigunga hagati ya f1 na f2 mubishusho (a) “bigabanuka” “Is 38 dB.Igisubizo cyanyuma cyo kugereranya nuko icyerekezo cyimbaraga za synthesis uburyo bwa 18dB hejuru ya Wilkinson.Iyi gahunda ikwiranye no gupima intermodulation ya amplifier icumi.
Icyerekezo gifatika gikoreshwa mumbaraga zihuza sisitemu 2
2, ikoreshwa mukwakira anti-intervention gupima cyangwa gupima spurious
Muri sisitemu yo gupima no gupima RF, uruziga rwerekanwe kumashusho hepfo rushobora kugaragara.Dufate ko DUT (igikoresho cyangwa ibikoresho biri kugeragezwa) niyakira.Muri icyo gihe, ikimenyetso cyegeranye cyumuyoboro gishobora kwinjizwa mubakira binyuze mumpera yanyuma yicyerekezo.Noneho ibizamini byahujwe bihuza nabo binyuze mubyerekezo bifatanyiriza hamwe bishobora kugerageza kwakira ababyakira - imikorere igihumbi yo kwivanga.Niba DUT ari terefone ngendanwa, imashini ya terefone irashobora gufungurwa nipimisha ryuzuye rihujwe no guhuza impera yicyerekezo.Noneho isesengura rya sprifike irashobora gukoreshwa mugupima ibisohoka bya terefone igaragara.Birumvikana, akayunguruzo kamwe kagomba kongerwaho mbere yisesengura.Kubera ko uru rugero ruvuga gusa ibyerekeranye no guhuza icyerekezo, akayunguruzo kasibwe.
Icyerekezo gifatika gikoreshwa mukurwanya anti-intervention gupima imashini yakira cyangwa uburebure bwa terefone igendanwa.
Muri iki kizamini cyizunguruka, icyerekezo cyerekezo gihuza ni ngombwa cyane.Isesengura rya sprifike ihujwe no kurangiza irashaka gusa kwakira ibimenyetso biva muri DUT kandi ntishaka kwakira ijambo ryibanga kuva iherezo.
3, kubimenyetso byo gutoranya no gukurikirana
Kohereza kumurongo no gupima no kugenzura birashobora kuba bimwe mubikoreshwa cyane muburyo bwo guhuza icyerekezo.Igishushanyo gikurikira nuburyo busanzwe bwo guhuza icyerekezo cyo gupima selile fatizo.Tuvuge ko imashini itanga imbaraga ari 43dBm (20W), guhuza icyerekezo.Ubushobozi ni 30dB, igihombo cyo kwinjiza (gutakaza umurongo wongeyeho igihombo cyo guhuza) ni 0.15dB.Impera yo guhuza ifite ikimenyetso cya 13dBm (20mW) yoherejwe mukigeragezo cya sitasiyo fatizo, ibisohoka bitaziguye byerekanwa ni 42,85dBm (19.3W), kandi kumeneka ni Imbaraga kuruhande rwitaruye zinjizwa numutwaro.
Icyerekezo gifatika gikoreshwa mugupima sitasiyo fatizo.
Hafi ya transmitter zose zikoresha ubu buryo bwo gutoranya no kugenzura kumurongo, kandi birashoboka ko ubu buryo bwonyine bushobora kwemeza ikizamini cyimikorere ya transmitter mubihe bisanzwe byakazi.Ariko twakagombye kumenya ko kimwe nikizamini cyohereza, kandi abipimisha batandukanye bafite impungenge zitandukanye.Dufashe stasiyo ya WCDMA nkurugero, abashoramari bagomba kwitondera ibipimo biri mumurongo wabo wogukora (2110 ~ 2170MHz), nkubwiza bwibimenyetso, mumiyoboro yumurongo, amashanyarazi yegeranye, nibindi. Muri iki cyemezo, ababikora bazashyiraho kuri ibisohoka birangirira kuri sitasiyo fatizo Umuyoboro muto (nka 2110 ~ 2170MHz) uhuza icyerekezo kugirango ukurikirane imiyoboro ya transmitter ikora kandi ikohereza mubigo bigenzura igihe icyo aricyo cyose.
Niba aribwo bugenzuzi bwa radiyo yumurongo wa radiyo-kugenzura radiyo kugirango igerageze ibipimo fatizo byoroshye, intego yayo iratandukanye rwose.Ukurikije ibisobanuro bya radiyo isabwa, ibipimo byikizamini byongerewe kugeza kuri 9kHz ~ 12.75GHz, kandi sitasiyo fatizo yageragejwe ni nini cyane.Ni bangahe imirasire idasanzwe izabyara umurongo wa radiyo kandi ikabangamira imikorere isanzwe yizindi sitasiyo?Impungenge za radiyo ikurikirana.Muri iki gihe, icyerekezo cyerekezo gifite umurongo umwe urasabwa kugirango ibimenyetso bitangwe, ariko icyerekezo gishobora gukwirakwiza 9kHz ~ 12.75GHz ntabwo gisa nkaho kibaho.Turabizi ko uburebure bwikiganza cyo guhuza icyerekezo gifitanye isano ninshuro yacyo hagati.Umuyoboro mugari wa ultra-Broadband icyerekezo cyerekezo gishobora kugera kuri 5-6 octave, nka 0.5-18GHz, ariko umurongo wumurongo uri munsi ya 500MHz ntushobora gutwikirwa.
4, gupima ingufu kumurongo
Muburyo bwa tekinoroji yo gupima imbaraga, icyerekezo cyerekezo nigikoresho gikomeye.Igishushanyo gikurikira cyerekana igishushanyo mbonera cyibisanzwe byanyuze muri sisitemu yo gupima imbaraga nyinshi.Imbaraga zimbere ziva muri amplifier munsi yikizamini ziteganijwe nicyerekezo cyo guhuza imbere (terminal 3) yicyerekezo cyoherejwe no koherezwa kuri metero yumuriro.Imbaraga zigaragazwa nicyitegererezo cyo guhuza itumanaho (terminal 4) no koherezwa kuri metero yimbaraga.
Icyerekezo gifatika gikoreshwa mugupima imbaraga nyinshi.
Nyamuneka Icyitonderwa: Usibye kwakira imbaraga zigaragara zivuye mumuzigo, guhuza guhuza kwinyuma (terminal 4) nayo yakira imbaraga ziva kumurongo ugana imbere (terminal 1), biterwa nubuyobozi bwa coupler yerekeza.Ingufu zigaragazwa nicyo ikizamini cyizera gupima, kandi imbaraga zo kumeneka nisoko yambere yamakosa mugupima imbaraga zigaragara.Imbaraga zigaragazwa nimbaraga zo kumeneka zirengerwa kumpera zinyuranye (impera 4) hanyuma zoherezwa kuri metero yumuriro.Kubera ko inzira zo kohereza ibimenyetso byombi zitandukanye, ni vector superposition.Niba imbaraga ziva mumashanyarazi zishobora kugereranwa nimbaraga zigaragara, bizatanga ikosa rikomeye ryo gupima.
Byumvikane ko imbaraga zigaragara zivuye mumuzigo (iherezo rya 2) nazo zizatemba zerekeza kumpera yimbere (iherezo 1, ntabwo ryerekanwa mumashusho hejuru).Nubwo bimeze bityo, ubunini bwayo ni buke ugereranije nimbaraga zimbere, zipima imbaraga imbere.Ikosa rivuyemo rirashobora kwirengagizwa.
Beijing Rofea Optoelectronics Co., Ltd iherereye mu Bushinwa “Silicon Valley” - Beijing Zhongguancun, ni ikigo cy’ikoranabuhanga rikomeye cyahariwe gukorera ibigo by’ubushakashatsi mu gihugu no mu mahanga, ibigo by’ubushakashatsi, kaminuza ndetse n’abakozi bashinzwe ubushakashatsi mu bumenyi.Isosiyete yacu ikora cyane cyane mubushakashatsi niterambere byigenga, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi bitanga ibisubizo bishya hamwe na serivise zumwuga, zihariye kubashakashatsi ba siyanse n'abashinzwe inganda.Nyuma yimyaka myinshi yo guhanga udushya, yakoze urutonde rwinshi kandi rwuzuye rwibicuruzwa byamashanyarazi, bikoreshwa cyane mumijyi, igisirikare, ubwikorezi, amashanyarazi, imari, uburezi, ubuvuzi nizindi nganda.
