AD8302 Wideband Amplitude Phase Detection Impedance Analysis Module Amplifier Filter Mixer Loss and Phase Measurement

Feature:

Single chip silicon bipolar device, amplitude / phase measurement

The AD8302 is a fully integrated RF IC that measures the amplitude and phase between two independent input signals. The device operates from low frequencies to 2.7 GHz.

The AD8302 contains two precision-matched wideband log amps, a wideband linear multiplier/phase detector, a 1.8V precision voltage reference, and an analog output proportional operation circuit.

The input signal range is -60 dBm to 0dBm (reference impedance 50Ω) with a corresponding dynamic range of 60dB.

The AD8302 output provides accurate amplitude measurements in the +/-30dB range with a slope of 30mV/dB; a phase measurement range of 0 to 180° with a slope of 10mV/degree.

Note: Please refer to application note AN-691 for module low frequency detection. The AD8302 is available in a 14-pin TSSOP package and operates over a temperature range of -40°C to 85°C.

 

Module application:

 

1. Measurement of insertion loss and phase of an amplifier, filter or mixer

2. Measure the vector reflection coefficient of any load

3. Impedance analysis
