AD8302 Amplitude Phase Detection Module 2.7 GHzRF/IF 14TSSOP RF Intermediate Frequency Phase Detection

Description AD8302 is the first monolithic integrated chip for RF IF amplitude and phase measurement launched by ADI in the United States in 2001 It can simultaneously measure the amplitude ratio and the amplitude ratio between two input signals in the frequency range from low frequency to 2 7GH z Phase difference The device contains two precision matched broadband logarithmic detectors a phase detector output amplifier group a bias unit and an output reference voltage buffer etc which can reduce the source of error and related temperature drift to a minimum AD8302 has the following main features 1 The amplitude ratio gain and phase difference of two input signals can be measured in the frequency range from low frequency to 2 7G Hz 2 When measuring the gain the dynamic range of the two input signals is ±30dB the sensitivity of the output level is 30mV dB and the error is less than 0 5dB The output voltage corresponding to 30dB is 30mV and the output voltage corresponding to 30dB is 1 8V The output current is 8mA and the conversion rate is 25V μ s 3 The scale factor of accurate amplitude measurement is 30mV dB 4 The accurate typical value is less than 0 5dB 5 The exact typical value is less than 1° 6 When the device is in operation it has three working modes measurement control and level comparison 7 With 1 8V reference voltage bias output 8 The video bandwidth response is 30M Hz 9 Working with a single power supply of 2 7V 5 5V 10 Us
