Ukuqonda ama-acterocators aholwa: Umhlahlandlela wokulawulwa kwesiginali ye-RF

Ama-Acterocators aholwayo yizakhi ezibalulekile kuzinhlelo zokusebenza zeRF (Radio Frequency) zenzelwe ukunciphisa izinga lamandla kusizinda ngaphandle kokuhlanekezela kakhulu i-waveform yayo. Bajwayele ukusetshenziswa ezinhlotsheni eziningi ze-elekthronikhi, njengezinhlelo zokuxhumana, imishini yokuhlola, namadivaysi ezokwelapha, ukulawula amandla esiginali nokuvikela ukulayisha ngokweqile kwesiginali.

Umsebenzi oyinhloko we-attenuator eholwayo ukuhlinzeka ngenani elinqunyelwe noma eliguquguqukayo le-attenuation, elivezwa ngokujwayelekile kuma-decibels (DB). Leveli le-attenuation lingashintshwa ngokushintsha inani lokumelana ne-attenuator. Ama-actonuators aholwayo angahlukaniswa ezinhlotsheni ezimbili eziphambili: Abatholi abahleliwe kanye nabahlinzeki abahlukahlukene.

Ama-actenuators alungisiwe anezinga elithile le-attenuation acacisiwe angeke aguqulwe. Zivame ukusetshenziswa kuzinhlelo zokusebenza lapho kudingeka khona izinga le-atteation ye-atlogy eqhubekayo, njengokuthi kuma-amplifiers wesiginali noma ama-mixers. Ama-Actenuators aguqukayo, ngakolunye uhlangothi, avumele amazinga aguqukayo aguqukayo, abenze afanelekele izinhlelo zokusebenza lapho amandla wesiginali edinga ukulawulwa ngamandla.

Ama-actonecators aholwa ngokujwayelekile akhiwa ngokujwayelekile kusetshenziswa izinto zokulwa nezinqubo ezisezingeni eliphakeme, njengefilimu eliminyene noma amafilimu ancanyana, ukuqinisekisa ukusebenza okunembile nokwethembekile. Zifakwe kwiphakheji eholwayo, enikeza ukuvikelwa ngokomzimba kanye nokuhlanganiswa okulula kwimibuthano ye-elekthronikhi.

Kuhlelo lokusebenza lwe-RF, abalandeli abaholwayo badlala indima ebalulekile ekulondolozeni ubuqotho besiginali, benciphisa ukuboniswa kwesiginali, kanye nokwenza ngcono ukusebenza kohlelo lonke. Zivame ukusetshenziselwa ukuhlangana nezinye izingxenye ze-RF, ezinjengezimpikiswano, izihlungi, kanye nezimpondo, zokwandisa ukuhanjiswa kwesiginali nokwamukela.

Ekuphetheni, abalandeli abaholwayo bayizinto ezibalulekile ezihlelweni ze-RF ezinikezela ngokulawulwa okuqondile ngamandla wesiginali futhi basize ukuqinisekisa ukusebenza kahle kwamadivayisi we-elekthronikhi. Ukusebenza kwazo kanye nokwethenjwa kwenza ukuthi babenze basebenzise amathuluzi asemqoka onjiniyela nabaqambi abasebenza emkhakheni wezobuchwepheshe be-RF.
