GENERAL DESCRIPTION AND THEORY The AD8302 measures the magnitude ratio, defined here as gain, and phase difference between two signals. A pair of matched logarithmic amplifiers provide the measurement, and their hard-limited outputs drive the phase detector. Basic Theory Logarithmic ...
Page 16
AD8302 Note that by convention, the phase difference is taken in the range from –180° to +180°. Since this style of phase detector does not distinguish between ±90° considered to have an unambiguous 180° phase difference range that ...

Interfacing to the Input Channels The single-ended input interfaces for both channels are identical. Each consists of a driving pin, INPA and INPB, and an ac- grounding pin, OFSA and OFSB. All four pins are internally dc-biased at about 100 ...

AD8302 Cross Modulation of Magnitude and Phase At high frequencies, unintentional cross coupling between signals in Channels A and B inevitably occurs due to on-chip and board- level parasitics. When the two signals presented to the AD8302 inputs are at ...

The comparator mode can be turned into a controller mode by closing the loop around the VMAG and VPHS outputs. Figure 11 illustrates a closed loop controller that stabilizes the gain and phase of a DUT with gain and phase ...
