为解决C波段功率合成中相位测量的问题，该文介绍了一种用于RF/IF幅度和相位测量的AD8302芯片，并利用它的鉴相功能实现了一款C波段的鉴相器的设计。首先采用前端变频电路将信号频率变换到AD8302可以处理范围内，然后利用AD8302进行相位差的测量。测试结果与芯片说明手册的鉴相结果相吻合。

In order to detect the phase difference between the C band microwaves which we need to do power combining, the paper introduces the chip AD8302 which usually be used to measure the gain/loss and phase in RF/IF system. Then the paper re-ports the design of a C band phase detector that based on the phase measurement function of AD 8302. First, the front-end of fre-quency conversion circuit is introduced, it converts the C band input microwaves to appropriate frequency that can be processed directly in AD8302. Then, AD8302 module measures the phase difference. The last, the measurement result well agrees with the datasheet of the chip.
