50 dB GSM PA控制器

AD8315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(dòng)態(tài)范圍為50 dB，主要用于蜂窩手機(jī)和其它電池供電的無線設(shè)備。與使用二極管檢波器的控制器相比，對(duì)數(shù)放大器技術(shù)提供的測(cè)量范圍更寬、精度更高，在-30°C至+85°C額定溫度范圍內(nèi)的溫度穩(wěn)定性尤為出色。\n\n 同時(shí)靈敏度較高，允許以較低信號(hào)電平進(jìn)行控制，從而降低了耦合至檢波器所需的功耗。\n\n AD8315提供MSOP和LFCSP兩種封裝，采用2.7 V至5.5 V電源供電，功耗為8.5 mA。進(jìn)入省電模式時(shí)，休眠電流為4 μA。 ? 完整RF檢波器/控制器功能\n\n? 動(dòng)態(tài)范圍：>50 dB\n(0.9 GHz，-49 dBm至+2 dBm，re 50 Ω)\n\n? 精確調(diào)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(yīng)\n\n? 對(duì)數(shù)斜率：23 mV/dB，\n截距：-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;
