[原创] ADI ADAR1000四路8GHz－16GHz波束形成解决方案

ADI公司的ADAR1000是四路X波段和Ku波段(8GHz-16GH)z波束形成核集成电路,器件在接收和发送模式间半双工模式.接收模式,输入信号通过四路接收通路在RF_IO引脚组合,发送模式,RF_IO输入信号分列并通过四路发送通路.在两种模式,提供≥31 dB增益调整范围和360°相位调整范围,分辨率优于6比特(≤0.5 dB 和2.8°).集成了四路-20dBm到+10dBM功率检测器和温度传感器,四线SPI接口.主要用在相控阵雷达和卫星通信系统.本文介绍了ADAR1000主要特性和功能框图,以及评估板ADAR1000-EVALZ主要特性,连接图,电路图和PCB设计图.

The ADAR1000 is a 4-channel, X and Ku frequency band, beamforming core chip for phased arrays. This device operates in half-duplex between receive and transmit modes. In receive mode, input signals pass through four receive channels and are combined in a common RF_IO pin. In transmit mode, the RF_IO input signal is split and passes through the four transmit channels. In both modes, the ADAR1000 provides a ≥31 dB gain adjustment range and a full 360° phase adjustment range in the radio frequency (RF) path, with better than 6-bit resolution (less than ≤0.5 dB and 2.8°, respectively).
