Digitaal kontroleare ferswakkers Digitale kontrôlestap
In digitaal kontroleare ferswakker is in mikrogolfkomponint dy't de ferswakkingshoeveelheid kin kontrolearje fia digitale sinjalen.
It ymplemintaasjeprinsipe is om de demping fan it sinjaal te kontrolearjen troch de steat fan 'e ynterne komponint of de grutte fan it ynfiersignaal oan te passen, wêrtroch't de wjerstânswearde feroare wurdt. Yn ferliking mei tradisjonele meganyske ferswakkers en fariabele wjerstannen.
Digitaal kontroleare ferswakkers hawwe de folgjende foardielen:
1. Hege presyzje: De digitale kontrôle-attenuator kin hege-presyzje kontrôle fan demping berikke fia digitale kontrôle, meastal berikt in krektens fan 0.1dB of minder.
2. Breedbân: Digitale ferswakkers wurkje typysk yn it GHz- of sels THz-berik en hawwe in brede bânbreedte.
3. Grut dynamysk berik: De digitale stapferswakker kin in ferstelber berik berikke fan 0dB oant 60dB of heger, en it oanpassingsberik is breed.
4. Programmeerbere kontrôle: De digitale kontrôle-attenuator kin programmearre wurde fia digitale ynterfaces lykas SPI en I2C, mei hege fleksibiliteit.
Digitaal kontroleare ferswakkers wurde benammen brûkt yn fjilden lykas mikrogolftesten, radar, kommunikaasje en satellytkommunikaasje. As wy de testapplikaasje as foarbyld nimme, kin de digitale kontrôleferswakker brûkt wurde om it fermogen fan it testsignaal oan te passen om de gefoelichheid en lineariteit fan 'e DUT (Device Under Test) te mjitten; kin brûkt wurde om it testsysteem te kalibrearjen om de krektens en konsistinsje te garandearjen; it kin brûkt wurde foar simulaasjetestscenario's om de anty-ynterferinsjeprestaasjes fan it systeem te evaluearjen tsjin ferskate ynterferinsje- en kanaalomstannichheden.
Kwalwaveleveret breedbân en heechdynamysk berik digitaal kontroleare ferswakkers by frekwinsjes oant 40 GHz. De stap kin 0,25 dB wêze en it ferswakkingsberik kin 100 dB of sels mear wêze. Us digitaal kontroleare ferswakkers hawwe goede kwaliteit en hege betrouberens, mei mear as 70 ûnderdielnûmers, dy't kinne foldwaan oan 'e behoeften fan ferskate klanten en wurde breed brûkt yn meardere fjilden.
