Детекторы среднеквадратичного напряжения

Измерение мощности сигнала сложной формы в системах с распределенным спектром CDMA / W-CDMA и в системах с QAM модуляцией высокого порядка всегда сопряжено с трудностями. Analog Devices разработал детекторы мощности TruPwr™, с помощью которых производится измерение мощности высокочастотных сигналов. Детекторы TruPwr™ выдают постоянное напряжение, точно соответствующее уровню среднеквадратического значения (RMS) сигнала. В семейство TruPwr™ входят детекторы мощности, предназначенные для проводных и беспроводных систем связи, а также детекторы в очень маленьких корпусах для портативных устройств.
