AD8302 amplitude phase detection module broadband logarithmic amplifier phase detector module 2.7G RF IF -79489

Features:

1. The gain and phase difference of two input signals can be measured from low frequency to 2.7 GHz. AD8302 is not only suitable for measuring the gain and phase difference of amplifiers, mixers and other circuits, but also suitable for testing wireless base stations and test equipment.

2. When measuring the gain, the dynamic range of the two input signals is ±30 dB, and the sensitivity of the output level is 30 mVdB. The error is less than 0.5 dB. 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/μs.

3. The ratio coefficient of accurate amplitude measurement is 30 mVdB.

4. The precise typical value is less than 0.5dB; (The range of phase difference measured by AD8302 is 0° ~180°, the corresponding output voltage range is 0~1.8V, the sensitivity of output voltage is 10mV/(°), and the measurement error is less than 0.5°). The output voltage is 1.8V when the phase difference (p=0). The output voltage is 30mV and the output current is 8mA when p=180 degrees. The conversion rate of phase output is 30MHz, and the response time is 40ns~500ns (depending on the measured phase difference);.

5. The proportional coefficient of accurate phase measurement is 10 mV/(°).

6. The exact typical value is less than 1 degree.

7. The device operates in three ways: measurement, control and level comparison.

8. With a stable 1.8V reference voltage bias output;

9. Video bandwidth response is 30MHz.

10. Use 2.7V~5.5V single power supply.

11. The internal structure of AD8302 mainly includes two precisely matched demodulated broadband logarithmic amplifiers, a multiplier type broadband phase detector, three adders (), a set of output amplifiers, bias circuits and reference voltage buffers. The input signal can be either a single-ended signal or a differential signal.
