Siffofin ayyuka na sauya RF

Sannu, zo don tuntuɓar samfuranmu!

RF da injin microwave na iya aika sigina da inganci a hanyar watsawa.Ana iya siffanta ayyukan waɗannan maɓallai da mahimman sigogin lantarki guda huɗu.Kodayake sigogi da yawa suna da alaƙa da aikin RF da injin microwave, ana ɗaukar sigogi huɗu masu zuwa da mahimmanci saboda ƙaƙƙarfan alaƙar su:

Kaɗaici
Keɓewa shine raguwa tsakanin shigarwa da fitarwa na kewaye.Yana da ma'auni na tasirin yanke-kashe na sauyawa.

Asarar shigarwa
Asarar shigarwa (wanda kuma ake kira asarar watsawa) ita ce jimlar ƙarfin da aka rasa lokacin da mai kunnawa ke kunne.Asarar shigar ita ce mafi mahimmancin ma'auni ga masu zanen kaya saboda zai iya kai tsaye ya haifar da haɓaka ƙirar tsarin amo.

Lokacin sauyawa
Sauyawa lokaci yana nufin lokacin da ake buƙata don sauyawa daga "on" jiha zuwa "kashe" jiha kuma daga "kashe" jiha zuwa "on" jiha.Wannan lokacin na iya kaiwa microseconds na babban ikon sauya wuta da nanoseconds na ƙaramin ƙarfin babban saurin saurin gudu.Mafi yawan ma'anar lokacin sauyawa shine lokacin da ake buƙata daga wutar lantarki mai sarrafa shigarwa ya kai 50% zuwa ƙarfin fitarwa na RF na ƙarshe ya kai 90%.

Ƙarfin sarrafa wutar lantarki
Bugu da kari, ana ayyana ƙarfin sarrafa wutar lantarki azaman matsakaicin ƙarfin shigarwar RF wanda maɓalli zai iya jurewa ba tare da lalata wutar lantarki ta dindindin ba.

Maɓallin RF mai ƙarfi
Za'a iya raba maɓallan RF mai ƙarfi zuwa nau'in mara tunani da nau'in tunani.Maɓallin da ba a juyo ba yana sanye take da 50 ohm matching matching resistor a kowane tashar fitarwa don cimma ƙarancin ƙarfin ƙarfin ƙarfin lantarki (VSWR) a cikin jihohi da kashewa.Resistor na tashar da aka saita akan tashar fitarwa na iya ɗaukar ƙarfin siginar abin da ya faru, yayin da tashar jiragen ruwa ba tare da tsayayyar madaidaicin tasha ba zai nuna siginar.Lokacin da siginar shigarwa dole ne a yada shi a cikin maɓalli, buɗe tashar tashar da ke sama za ta katse daga madaidaicin resistor, don haka barin ƙarfin siginar ya yadu gaba ɗaya daga maɓalli.Maɓallin sha ya dace da aikace-aikace inda ake buƙatar rage girman ma'anar amsawar tushen RF.

Sabanin haka, ba a sanye take da maɓalli masu haske tare da resistors na tasha don rage asarar shigar tashoshin jiragen ruwa.Maɓallai masu juyawa sun dace da aikace-aikacen da ba su da hankali ga babban ƙarfin igiyoyin igiyar wuta a wajen tashar jiragen ruwa.Bugu da kari, a cikin na'urar kunnawa, impedance matching an gane ta wasu aka gyara ban da tashar jiragen ruwa.

Wani sanannen siffa na ƙwanƙwaran juzu'i shine da'irori na tuƙi.Wasu nau'ikan maɓalli masu ƙarfi an haɗa su tare da direbobi masu sarrafa wutar lantarki.Halin dabarun sarrafa ƙarfin shigarwar waɗannan direbobi na iya cimma takamaiman ayyuka na sarrafawa - samar da halin yanzu da ake buƙata don tabbatar da cewa diode na iya samun jujjuyawar wutar lantarki ko gaba.

Za'a iya sanya maɓallan wutar lantarki da ƙarfi na RF zuwa samfura iri-iri tare da ƙayyadaddun marufi daban-daban da nau'ikan masu haɗawa - yawancin samfuran canjin coaxial tare da mitoci masu aiki har zuwa 26GHz suna amfani da masu haɗin SMA;Har zuwa 40GHz, 2.92mm ko mai haɗa nau'in K za a yi amfani da shi;Har zuwa 50GHz, yi amfani da mai haɗin 2.4mm;Har zuwa 65GHz amfani da masu haɗin 1.85mm.
