Measurement of Amplitude Ratio and Phase Difference in the Ultra-Wideband Microwave Receiving System

摘要：

To obtain the system information of Ultra-Wideband microwave receiving system, accurate measurement of amplitude change and phase change of antenna received signal and antenna transmit signal has a very important practical significance. In this paper, the ADIs single-chip silicon bipolar devices RF/IF gain and phase detector AD8302 is used as a core components in a wideband amplitude ratio and phase difference measurement system which can work from low frequency to 2.7GHz. The measurement system is composed of three parts; they are RF power attenuator, dual operational amplifier TLC2202, and detector AD8302. Experiment results show that the output voltage VMAG of AD8302 has a linear relationship with the two input signal amplitude ratio, and the VPHS of AD8302 will change with input phase difference change. It meets the requirement of measurement of phase difference and amplitude ratio in the Ultra-Wideband microwave receiver system.
