Isixhobo sokukhulisa ividiyo se-Detector Log, 0.5~10GHz, -60~0dBm, 14mV/dB

Isandisi-lizwi seVidiyo yeLog yesiVavanyiIi-s (ii-DLVA) ziyinxalenye yokulungisa isignali ephambili kwiinkqubo zanamhlanje ze-RF kunye nee-microwave. Ifumanisa ngokuthe ngqo isignali ye-RF engenayo, yandisa isignali ye-voltage yevidiyo ephumayo, kwaye ekugqibeleni ikhupha i-voltage ye-DC enobudlelwane obuhambelanayo namandla e-RF engenayo. Ngamazwi alula, i-detector log video amplifier yi-converter ehambelanayo ukusuka "kumandla e-RF ukuya kwi-voltage ye-DC." Ixabiso layo eliphambili likwikhono layo lokucinezela imiqondiso ye-RF enoluhlu olukhulu kakhulu oluguquguqukayo ukuya kwisignali ye-voltage ye-DC elawulekayo, encinci, ngaloo ndlela yenza lula kakhulu imisebenzi elandelayo yokucubungula isignali efana nokuguqulwa kwe-analog ukuya kwidijithali, ukuthelekisa/ukwenza izigqibo, kunye nokubonisa.

Iimbonakalo:

1. Ukugubungela ifrikhwensi ye-Ultra-wideband
Uluhlu lweefrikhwensi zokusebenza lugubungela i-0.5GHz ukuya kwi-10GHz, nto leyo evumela ukusetyenziswa kuluhlu olubanzi ukusuka kwi-L-band ukuya kwi-X-band. Iyunithi enye inokutshintsha izixhobo ezininzi ze-narrowband, nto leyo eyenza kube lula ukuyila inkqubo.
2. Uluhlu oluguquguqukayo olungaqhelekanga kunye novakalelo
Inika igalelo elibanzi lobubanzi obuguqukayo ukusuka kwi--60dBm ukuya kwi-0dBm. Oku kuthetha ukuba inokulinganisa ngokuchanekileyo imiqondiso ukusuka kobuthathaka kakhulu (-60dBm, inqanaba le-nanowatt) ukuya komeleleyo (0dBm, inqanaba le-milliwatt) ngaxeshanye, okwenza ukuba ifaneleke ukubamba "imiqondiso emincinci egqunywe yimiqondiso emikhulu."
3. Ulungelelwano oluchanekileyo lwelog kunye nokuhambelana
Inika ulungelelwaniso oluhle kakhulu lwelog kulo lonke uluhlu oluguquguqukayo kunye nebhendi yefrikhwensi. I-voltage ye-DC ephumayo igcina ubudlelwane obuqinileyo obuhambelanayo namandla e-RF angenayo, iqinisekisa iziphumo zokulinganisa amandla ezichanekileyo nezithembekileyo. Ukuhambelana okuphezulu kufezekiswa phakathi kweetshaneli (kwiimodeli zetshaneli ezininzi) nakwiibhetshi zemveliso.
4. Isantya sokuphendula esikhawulezayo kakhulu
Ibonisa amaxesha okunyuka/ukuwa kwevidiyo kwinqanaba le-nanosecond kunye nokulibaziseka kokucubungula isignali. Ingalandelela ngokukhawuleza umahluko wesandisi esiguquliweyo se-pulse-modulated signals, ihlangabezana neemfuno zexesha langempela zezicelo ezifana nohlalutyo lwe-radar pulse kunye namanyathelo okuxhasa nge-elektroniki (ESM).
5. Ukuhlanganiswa okuphezulu kunye nokuthembeka
Isebenzisa itekhnoloji yokuxhoma umphezulu kunye noyilo oludibeneyo lwemodyuli, ibandakanya isixhobo sokubona, i-logarithmic amplifier, kunye nesekethe yokuhlawula ubushushu ngaphakathi kwendlu encinci, ekhuselweyo. Ibonisa uzinzo oluhle lobushushu kunye nokuthembeka kokusebenza ixesha elide, ifanelekile kwiindawo ezifuna amandla omkhosi kunye nezoshishino.

Izicelo:

1. Iinkqubo zemfazwe ye-elektroniki (EW) kunye ne-signals intelligence (SIGINT)
Amanyathelo okuxhasa nge-elektroniki (ESM): Isebenza njengesixhobo sokufumana isilumkiso se-radar (RWR), ilinganisa ngokukhawuleza, ichonge, kwaye ifumane amandla emiqondiso ye-radar enobutshaba ukuze iqonde ngengozi kwaye ivelise imifanekiso yemeko ethile.
Ubukrelekrele be-elektroniki (ELINT): Ihlalutya ngokuchanekileyo iimpawu ze-pulse (ububanzi be-pulse, i-frequency yokuphindaphinda, amandla) yezibonakaliso ze-radar ezingaziwayo zokuhlelwa kwesignali kunye nophuhliso lwedathabheyisi yesiginitsha.
2. Iinkqubo zokubeka esweni nokulawula iispektrum
Ijonga umsebenzi wesignali kwibhendi ebanzi yamaza ngexesha langempela, ilinganisa ngokuchanekileyo amanqanaba amandla emiqondiso yokuphazamiseka okungekho mthethweni okanye imiqondiso enobuhlobo. Isetyenziselwa ukubonisa imeko yespectrum, indawo yomthombo wokuphazamiseka, kunye nokujonga ukuthotyelwa kwespectrum.
3. Izixhobo zovavanyo oluphezulu kunye nokulinganisa
Ingasetyenziswa njengemodyuli yokubona amandla abalulekileyo kwii-vector network analyzers (VNA), ii-spectrum analyzers, okanye izixhobo zovavanyo ezikhethekileyo, ukwandisa amandla okulinganisa ububanzi besixhobo, ngakumbi ukugqwesa ekulinganiseni amandla e-pulse.
4. Iinkqubo zeradar
Isetyenziselwa ukujonga ulawulo lokunyuswa ngokuzenzekelayo (AGC) kwiitshaneli zokufumana i-radar, ukujonga ukuphuma kwamandla okudlulisa, okanye ukusebenza njengeyunithi yokukhawulela kunye nokufumanisa amandla ngaphambili kwezixhobo zokwamkela zedijithali (DRx) ukukhusela izinto ezibuthathaka ezilandelayo.
5. Unxibelelwano kunye nophando lwelebhu kunye nophuhliso
Isetyenziselwa ukujonga amandla onxibelelwano kunye nokulinganisa kwiinkqubo zonxibelelwano lwe-broadband (umz., unxibelelwano lwesathelayithi, uphononongo nophuhliso lwe-5G/mmWave). Kwilabhoratri, sisixhobo esisebenzayo sohlalutyo lweempawu zesignali ye-pulse kunye novavanyo lokuntywila kwamandla.
