Amplifier ya video ya kumbukumbu ya kigunduzi hutumiwa zaidi katika mifumo ya mawasiliano kama vile rada, mifumo ya vita vya kielektroniki na mawasiliano ya setilaiti. Katika mifumo hii, kipaza sauti cha logi cha kigunduzi kinaweza kusaidia katika kuchakata mawimbi ya RF, kutoa taarifa muhimu, na kuzibadilisha kuwa ishara za video zinazofaa kwa usindikaji zaidi. Kwa kuongeza, amplifaya ya video ya kumbukumbu ya kigunduzi pia inaweza kutumika katika nyanja kama vile kutafuta mwelekeo wa redio na ufuatiliaji wa kuingiliwa kwa redio.
Ikumbukwe kwamba amplifier ya video ya logi ya detector sio amplifier ya ulimwengu wote, na muundo na matumizi yake yanahitaji kuboreshwa kulingana na mifumo maalum ya mawasiliano na matukio ya maombi. Wakati huo huo, unapotumia amplifier ya video ya logi, tahadhari inapaswa pia kulipwa kwa hali yake ya kazi na vikwazo ili kuepuka matatizo kama vile uharibifu au uharibifu wa utendaji.
1. Unyeti wa hali ya juu: Kikuza sauti cha logi cha kigunduzi kinaweza kupokea mawimbi dhaifu sana ya RF na kuwageuza kuwa mawimbi ya video.
2. Kelele ya chini: Kwa kuwa mawimbi ya RF mara nyingi ni dhaifu sana, kipaza sauti cha kumbukumbu cha kigunduzi kinahitaji kuwa na sifa za chini za kelele ili kuhakikisha uwazi na usahihi wa mawimbi.
3. Upeo mpana unaobadilika: Kikuza sauti cha kumbukumbu ya kigunduzi kinahitaji kuwa na masafa pana inayobadilika ili kuendana na nguvu tofauti za mawimbi na masafa ya masafa.
4. Mstari mzuri na uthabiti: Ili kuhakikisha usahihi na kutegemewa kwa usindikaji wa mawimbi, amplifier ya video ya logi inahitaji kuwa na mstari mzuri na uthabiti.
Qualwavehutoa Vikuza Video vya Kigundua Ingia (DLVA) kutoka DC hadi 40GHz, na TSS iko chini kama -72dBm.
