Isikhulisi Sevidiyo Se-Detector Log, 0.5~10GHz, -60~0dBm, 14mV/dB

Isikhulisi Sevidiyo Selogi YesitholiAma-s (ama-DLVA) ayisici esiyinhloko sokulungisa isignali ezinhlelweni zesimanje ze-RF kanye ne-microwave. Yenza ngqo ukutholwa okuphezulu kwesignali ye-RF yokufaka, ikhulisa isignali ye-voltage yevidiyo ephumayo nge-logarithmically, futhi ekugcineni ikhiphe i-voltage ye-DC enobudlelwano obuqondile namandla e-RF yokufaka. Ngamagama alula, i-detector log video amplifier iyi-converter eqondile kusukela "kumandla e-RF kuya ku-voltage ye-DC." Inani layo eliyinhloko lisekhonweni layo lokucindezela amasignali e-RF ngebanga elikhulu kakhulu eliguquguqukayo libe yisignali ye-voltage ye-DC elawuleka kalula, encane, ngaleyo ndlela yenza kube lula kakhulu imisebenzi elandelayo yokucubungula amasignali njengokuguqulwa kwe-analog kuya kudijithali, ukuqhathanisa/ukwenza izinqumo, kanye nokubonisa.

Izici:

1. Ukumbozwa kwemvamisa ye-Ultra-wideband
Ibanga lemvamisa yokusebenza lihlanganisa i-0.5GHz kuya ku-10GHz, okuvumela uhlelo lokusebenza kububanzi obuhlukahlukene kusukela ku-L-band kuya ku-X-band. Iyunithi eyodwa ingathatha indawo yamadivayisi amaningi e-narrowband, okwenza kube lula ukwakheka kwesistimu.
2. Ububanzi obuguquguqukayo obungavamile kanye nokuzwela
Inikeza okokufaka okubanzi okuguquguqukayo kusukela ku--60dBm kuya ku-0dBm. Lokhu kusho ukuthi ingalinganisa ngokunembile amasignali asukela kubuthakathaka kakhulu (-60dBm, izinga le-nanowatt) kuya kunamandla kakhulu (0dBm, izinga le-milliwatt) ngasikhathi sinye, okwenza kube kuhle kakhulu ekuthwebuleni "amasignali amancane afihlwe amasignali amakhulu."
3. Ukulingana kwelogi okunembile kanye nokuvumelana
Inikeza ukulingana okuhle kakhulu kwelogi kulo lonke uhla oluguquguqukayo kanye nebhendi yemvamisa. I-voltage ye-DC ephumayo igcina ubudlelwano obuqinile obuqondile namandla e-RF okufakwayo, iqinisekisa imiphumela yokulinganisa amandla enembile nethembekile. Ukuvumelana okuphezulu kufinyelelwa phakathi kweziteshi (kwamamodeli aneziteshi eziningi) kanye nakuzo zonke izinhlobo zokukhiqiza.
4. Isivinini sokuphendula esisheshayo kakhulu
Iqukethe izikhathi zokwenyuka/ukuwa kwevidiyo ezingeni le-nanosecond kanye nokubambezeleka kokucubungula isignali. Ingakwazi ukulandelela ngokushesha ukuhlukahluka kwezimpawu eziguquliwe ze-pulse, ihlangabezane nezidingo zesikhathi sangempela zezinhlelo zokusebenza ezifana nokuhlaziywa kwe-radar pulse kanye nezinyathelo zokusekela ze-elekthronikhi (ESM).
5. Ukuhlanganiswa okuphezulu nokuthembeka
Isebenzisa ubuchwepheshe bokufaka phezulu kanye nomklamo wemodyuli ohlanganisiwe, ifaka i-detector, i-logarithmic amplifier, kanye ne-temperature compensation circuitry ngaphakathi kwendlu encane, evikelwe. Ibonisa ukuzinza okuhle kokushisa kanye nokuthembeka kokusebenza kwesikhathi eside, ifanelekela izindawo zempi nezimboni ezidinga kakhulu.

Izicelo:

1. Izinhlelo ze-electronic warfare (EW) kanye ne-signals intelligence (SIGINT)
Izindlela zokusekela ngogesi (ESM): Zisebenza njengesisekelo sangaphambi kwezamukeli zesexwayiso se-radar (RWR), zilinganisa ngokushesha, zihlonza, futhi zithole amandla ezimpawu ze-radar ezinonya ukuze kuqwashiswe ngosongo kanye nokukhiqizwa kwezithombe zesimo.
Ubuhlakani be-elekthronikhi (ELINT): Ihlaziya ngokunembile izici ze-pulse (ububanzi be-pulse, imvamisa yokuphindaphinda, amandla) wezimpawu ze-radar ezingaziwa zokuhlunga isignali kanye nokuthuthukiswa kwedathabheyisi yesiginesha.
2. Izinhlelo zokuqapha nokuphatha ama-spectrum
Iqapha umsebenzi wesignali kuyo yonke ibhendi yemvamisa ebanzi ngesikhathi sangempela, ilinganisa ngokunembile amazinga wamandla wesignali yokuphazamiseka okungekho emthethweni noma amasignali anobungane. Isetshenziselwa ukubona isimo se-spectrum, indawo yomthombo wokuphazamiseka, kanye nokuhlola ukuhambisana kwe-spectrum.
3. Amathuluzi okuhlola nokusebenza kahle kakhulu kanye nezinsimbi zokulinganisa
Ingasetshenziswa njengemojuli yokuthola amandla abalulekile kuma-vector network analyzers (VNA), ama-spectrum analyzers, noma imishini yokuhlola ekhethekile, okwandisa ikhono lokulinganisa ububanzi obuguqukayo bethuluzi, ikakhulukazi elihamba phambili ekulinganisweni kwamandla e-pulse.
4. Izinhlelo ze-radar
Isetshenziselwa ukuqapha ukulawula okuzenzakalelayo kokuthola (i-AGC) eziteshini zokwamukela i-radar, ukuqapha ukuphuma kwamandla okudlulisa, noma ukusebenza njengeyunithi yokukhawulela kanye nokuthola amandla ngaphambili kwezamukeli zedijithali (i-DRx) ukuvikela izingxenye ezibucayi ezilandelayo.
5. Ukuxhumana kanye nocwaningo kanye nokuthuthukiswa kwelebhu
Isetshenziselwa ukuqapha amandla okuxhumanisa kanye nokulinganisa ezinhlelweni zokuxhumana ze-broadband (isb., ukuxhumana kwesathelayithi, i-5G/mmWave R&D). Elabhorethri, iyithuluzi elisebenzayo lokuhlaziya izici zesignali ye-pulse kanye nokuhlolwa kokukhukhula kwamandla.

I-Qualwave Inc. inikeza ama-Detector Log Video Amplifier ahlanganisa kahle i-bandwidth ebanzi, ukuzwela okuphezulu, impendulo esheshayo, kanye nokulingana okuhle kakhulu, kanye nama-frequency afinyelela ku-40GHz.
Lo mbhalo wethula i-Detector Log Video Amplifier enokumbozwa kwemvamisa okungu-0.5 ~ 10GHz.
