AD8364: 低频至2.7GHz、双通道、60dB TruPwr™检波器

AD8364 功能框图AD8364是一款双通道TruPwr™检波器,旨在实现宽动态范围信号功率测量(> 60dB)。该产品提供比例精确地线性dB输出响应,相当于输入波形的均方根(RMS)值。AD8364在单芯片上集成两个匹配的独立通道,能够提供三个均方根输出电压,一个针对各输入通道、比例精确地独立输出,以及一个可以测量两个输入信号之间增益或损耗的差值输出。除均方根输出外,AD8364还提供与片内温度传感器所测的温度成比例关系的输出电压。AD8364具有较大的波峰因素,非常适合测量复合调制波形。它的波形和调制高效独立,因而用户能够获得高容量无线和有线通信网络中复合调制(QAM/QPSK/OFDM)波形的精确均方根电平。有关CDMA和W-CDMA功率测量的更多详细信息,请参见产品数据手册。

The AD8364 is a dual channel TruPwr™ detector, designed to provide wide dynamic range signal power measurement (> 60dB). The product provides an accurately scaled linear-in-dB output response, that is the equivalent Root-Mean-Square (RMS) of the input waveform.The AD8364 integrates two matched individual channels on a single IC, enabling three RMS output voltages, an accurately scaled independent output for each input channel and a difference output that can measure the gain or loss between the two input signals. In addition to the RMS outputs, the AD8364 provides an output voltage proportional to temperature from on chip temperature sensor.The AD8364 is ideally suited for the measurement of complex modulated waveforms, with large crest factors. The AD8364 is effectively waveform and modulation independent enabling the user to acquire a precise RMS level of complex modulated (QAM / QPSK / OFDM) wavefoms found high capacity wireless and wire-line communication networks. More detailed information on the CDMA and W-CDMA power measurements is shown within the product data sheet.
