50 dB GSM PA控制器

AD8311是一款用于精確控制RF功率放大器的低成本完整子系統(tǒng)，工作頻率范圍為0.1 GHz 至 2.5 GHz，典型動態(tài)范圍為50 dB，主要用于蜂窩手機和其它電池供電的無線設備。與使用二極管檢波器的控制器相比，對數(shù)放大器技術提供的測量范圍更寬、精度更高，在-40°C至+85°C額定溫度范圍內的溫度穩(wěn)定性尤為出色。\n\n 同時靈敏度較高，允許以較低信號電平進行控制，從而降低了耦合至檢波器所需的功耗。 ? 完整RF檢波器/控制器功能\n\n? 動態(tài)范圍：>50 dB\n(0.9 GHz，-48 dBm至+3 dBm, Re 50 Ω)\n\n? 精確調整范圍：0.1 GHz至2.5 GHz\n\n? 出色的溫度穩(wěn)定性，線性dB響應\n\n? 對數(shù)斜率：23 mV/dB，截距：\n-60 dBm (0.9 GHz)\n\n? 控制環(huán)路中的真積分功能\n\n? 低功耗：20 mW (2.7 V)，38 mW (5 V)\n\n? 省電模式：10.8 μW;
