标题: (EN) Active antenna associated device and system, and transmitting and receiving calibration method
摘要: front page image
(EN)

An active antenna associated device and system, and a transmitting and receiving calibration method, used for implementing extensible design of an antenna array, reducing construction implementation difficulty, and ensuring construction implementation reliability. The active antenna unit comprises: N active antenna arrays, a main calibration coupling circuit unit, a transmitting and receiving calibrating unit, a calibration parameter storage unit, and a radio over fiber (ROF) photoelectric conversion unit, wherein N is larger than 1. Each active antenna array at least comprises an antenna calibration coupling circuit unit and M antenna oscillators connected to the antenna calibration coupling circuit unit, wherein M is larger than 1. The antenna calibration coupling circuit units of the active antenna arrays are connected to the main calibration coupling circuit unit through a calibration radio frequency channel. The main calibration coupling circuit is connected with the transmitting and receiving calibrating unit. The transmitting and receiving calibrating unit and the calibration parameter storage unit are respectively connected to the ROF photoelectric conversion unit.
