L-amplifikatur tal-vidjo tal-log detector huwa prinċipalment użat f'sistemi ta 'komunikazzjoni bħal radar, sistemi ta' gwerra elettronika, u komunikazzjonijiet bis-satellita. F'dawn is-sistemi, l-amplifikatur tal-vidjo tal-log detector jista 'jgħin fl-ipproċessar ta' sinjali RF, estrazzjoni ta 'informazzjoni utli, u jikkonvertiha f'sinjali tal-vidjo adattati għal aktar ipproċessar. Barra minn hekk, l-amplifikatur tal-vidjo tal-log detector jista 'jiġi applikat ukoll f'oqsma bħas-sejba tad-direzzjoni tar-radju u l-monitoraġġ tal-interferenza tar-radju.
Għandu jiġi nnutat li l-amplifikatur tal-vidjo tal-log tad-detector mhuwiex amplifikatur universali, u d-disinn u l-applikazzjoni tiegħu jeħtieġ li jiġu ottimizzati skont sistemi speċifiċi ta 'komunikazzjoni u xenarji ta' applikazzjoni. Sadanittant, meta tuża amplifikatur tal-vidjo tal-log detector, għandha tingħata attenzjoni wkoll lill-kundizzjonijiet tax-xogħol u l-limitazzjonijiet tiegħu biex jiġu evitati problemi bħal ħsara jew degradazzjoni tal-prestazzjoni.
1. Sensittività għolja: L-amplifikatur tal-vidjo tad-detector jista 'jirċievi sinjali RF dgħajfa ħafna u jikkonvertihom f'sinjali tal-vidjo.
2. Ħoss baxx: Peress li s-sinjali RF ħafna drabi huma dgħajfa ħafna, l-amplifikatur tal-vidjo tal-log tad-detector jeħtieġ li jkollu karatteristiċi ta 'ħoss baxx biex jiżgura ċ-ċarezza u l-eżattezza tas-sinjal.
3. Firxa dinamika wiesgħa: L-amplifikatur tal-vidjo tal-log tad-detector jeħtieġ li jkollu firxa dinamika wiesgħa biex jadatta għal saħħiet tas-sinjali u firxiet ta 'frekwenza differenti.
4. Linearità tajba u stabbiltà: Sabiex jiġu żgurati l-eżattezza u l-affidabbiltà tal-ipproċessar tas-sinjal, l-amplifikatur tal-vidjo tal-log tad-detector jeħtieġ li jkollu linearità u stabbiltà tajba.
Qualwaveprovvisti Detector Log Video Amplifiers(DLVAs) minn DC sa 40GHz, u t-TSS huwa baxx daqs -72dBm.
