Amathuba Amasha Ekuxhumaneni Kwe-Microwave: Isixhumanisi Se-Analog Se-40GHzI-RF phezu kwefayibha
Emkhakheni wokuxhumana nge-microwave, izixazululo zokudlulisa zendabuko bezilokhu zivinjelwe yizinkinga ezimbili ezinkulu: izintambo ze-coaxial ezibizayo kanye nama-waveguides akugcini nje ngokwandisa izindleko zokuthunyelwa kodwa futhi kukhawulela kakhulu ukudluliselwa kwesignali ngebanga. Ngaphezu kwalokho, ukumbozwa kwebhendi yemvamisa kanye nokuqina kunzima ukuhlangabezana nezidingo zezinhlelo zokusebenza ze-broadband. Sibhekene nalesi simo, siyajabula ukukuncoma - uchungechunge lwe-ROFBox 40GHz lwangaphandle lwe-Modulation Broadband Analog Link RF phezu kwefayibha. Lokhu akuyona nje umkhiqizo; kuyiphepha lempendulo elihle kakhulu esilithumele ukuze sidlule imikhawulo yomzimba.
Lo mkhiqizo omusha usebenzisa ikhambi lokudlulisa ukukhanya le-optical modulation yangaphandle, elisekela ukuguqulwa kwesignali ye-RF ngaphandle kokulahlekelwa ngaphakathi kobubanzi obuhlukahlukene be-1-40GHz ultra-wideband. Uthatha indawo yemidiya yensimbi yendabuko ngeizixhumanisi zefayibha yokukhanya, iphula ngokuphelele imikhawulo ebonakalayo yebanga lokudlulisela. Inzuzo yayo eyinhloko itholakala ku:
Ukuthembeka okuphezulu kwebhendi ephelele: Ukumbozwa kwebhendi ebanzi engu-1-40GHz, kuhlanganiswe nomklamo olungiselelwe kahle, kuqinisekisa ukukhiqizwa kabusha okunembile kobukhulu besiginali kanye nesigaba. Ukwenyuka kokusebenza kahle kwezindleko: Gwema izintambo ze-coaxial ezibizayo kanye nezinhlangano ze-waveguide, kunciphisa izindleko zokufakwa ngaphezu kuka-60%; Ukuphumelela kwamandla okulwa nokuphazamiseka:Ukudluliswa kwefayibha yokukhanyaimelana ngokwemvelo nokuphazamiseka kwe-electromagnetic, futhi ukuzinza kwesignali ezindaweni eziyinkimbinkimbi kuthuthukiswe kakhulu.
Kusukela ekudlulisweni kwesignali ekuxhumaneni okungenantambo okude kuya ekwabiweni okunembile kwezibonakaliso zesikhathi, bese kuba ukusetshenziswa okungokoqobo kwezinhlelo ze-telemetry kanye nemigqa yokulibaziseka, ingakwazi ukuzivumelanisa kahle, inikeze ukwesekwa okuqinile kwezimo ezahlukahlukene ze-microwave ye-broadband futhi ivule imingcele engenzeka yokuchaza kabusha izinhlelo zokusebenza ze-microwave ye-analog broadband.
Incazelo Yomkhiqizo
Uchungechunge lwe-ROFBox lwe-broadband yokuguquguquka kwangaphandleIsixhumanisi se-Analog RF phezu kwefayibhaIsebenzisa imodi yokusebenza yokushintshashintsha kwangaphandle futhi ingahlinzeka ngokudluliselwa kwesignali ye-RF ngaphakathi kwebanga lemvamisa elingu-1-40GHz, inikeza ukuxhumana kwe-fiber optical okusebenzayo okuphezulu kwezinhlelo zokusebenza ezahlukahlukene ze-microwave ye-analog broadband. Ngokugwema ukusebenzisa izintambo noma ama-waveguides abizayo, ukulinganiselwa kwebanga lokudlulisela kuqediwe, okuthuthukisa kakhulu ikhwalithi yesignali kanye nokuthembeka kokuxhumana kwe-microwave. Ingasetshenziswa kabanzi emikhakheni yokuxhumana ye-microwave njengezintambo ezingenantambo ezikude, isikhathi, ukusatshalaliswa kwesignali yereferensi, i-telemetry kanye nemigqa yokulibaziseka.
