摘要
在移动通信系统中,经常需要精确测量相位差。详细阐述了利用AD8302构成的宽频带相位差及频率测量系统。该系统可精确测量从低频到射频范围内0°~360°的相位差(测量误差小于0.5)°,-60dBm~0dBm范围内的功率电平以及10MHz以下的频率。
In mobile communication system,it is often needs to accurately measure phase bias.The broad band phase bias and frequency measurement system made of AD8302 is expressed in this paper. The system can measure phase bias range of 0°~360° from low-frequency to RF (measure error less than 0.5°), power voltage from -60dBm to 0dBm and frequency below 10MHz.
