直接變頻TV調(diào)諧器

MAX3580是完全集成的直接變頻TV調(diào)諧器，設(shè)計(jì)用于數(shù)字電視地面廣播(DVB-T)應(yīng)用。集成調(diào)諧器的輸入頻率范圍覆蓋VHF-III波段的170MHz至230MHz和UHF的470MHz至878MHz。\n MAX3580直接變頻調(diào)諧器集成了RF輸入開關(guān)和多波段跟蹤濾波器，可實(shí)現(xiàn)低功耗板上調(diào)諧器，而不存在雙變頻調(diào)諧器方案的功耗和費(fèi)用等問題。零IF架構(gòu)將基帶I和Q直接輸出至解調(diào)器，無(wú)需SAW濾波器。另外，器件使用混合信號(hào)架構(gòu)在片上消除直流失調(diào)，可改善二階失真性能以及下行數(shù)字化和解調(diào)器的動(dòng)態(tài)范圍。\n MAX3580具有高于76dB的動(dòng)態(tài)增益控制，在中波段具有4.7dB的典型LNA等效輸入噪聲系數(shù) \n? 650mW功耗(VCC = +3.3V) \n? I和Q基帶輸出省去了所有IF-SAW濾波器 \n? 集成的RF跟蹤濾波器 \n? 可調(diào)的基帶低通濾波器 \n? VHF-III和UHF全波段調(diào)諧 \n? +38dB數(shù)字ACPR，+47dB模擬ACPR \n? 低噪聲系數(shù)：4.7dB (典型值) \n? N分頻合成器實(shí)現(xiàn)-90dBc/Hz的帶內(nèi)相噪 \n? +3.1V至+3.5V電源電壓范圍 \n? 超小尺寸、5mm x 5mm薄型QFN封裝;
