Product features:
-The phase difference between two columns of the same frequency signal is usually measured in electrical instrumentation, data processing of synchronous sensing, and phase frequency characteristics of the network. The conventional phase meter has a narrow operating band and a low frequency, and the accuracy is not high.
-The AD8302 accurately measures the phase difference of two independent signals up to 2.7 GHz and measures the amplitude ratio (gain) / loss of two columns. It consists of two-band logarithmic detectors, which match well with the logarithmic compression principle of the logarithmic amplifier.
-Therefore, it can be used to measure the gain and phase difference of circuits such as amplifiers and mixers and is particularly suitable for detecting wireless base stations.
-AD8302 internal structure consists of two precision matched demodulated broadband log amps, a multiplier type broadband phase detector, three adders (& sum;), a set of output amplifiers, bias circuits and reference buffers. The input signal can be a single ended signal or a differential signal.
Usage instructions:
-The gain outputs of the module are VMAG and MEST, phase difference outputs are shortened to VPHS and PSET measurement mode and operate at the default slope and center point. The phase difference output voltage proportional coefficient is 10mV / °, and the phase difference can be -180 ° to 0 °. The phase difference between the two measured signals is determined as positive or negative depending on the slope.
