Abstract

Large aperture phased array antennas are designed with fiber-optic distribution networks to provide phase and frequency reference signals, control signals for beam steering and shaping, and data/frequency hopping signals to MMIC active T/R modules. The experimental results of a FO communication network at millimeter wave frequency of 38GHz (Ka-band) are presented. The results of 500MHz-1GHz FO link characteristics such as frequency response flatness, harmonics, and the third order intermodulation distortion are presented. Results of stabilization of a 38GHz IMPATT oscillator using indirect optical injection locking is also discussed. A locking range of 132MHz using 45dB amplification gain is demonstrated. The overall system FM noise degradation is measured to be 16dB. The communication link is established by up-conversion of the data link with the stabilized LO. Results of a true time delay phase shifter using a novel fiber striching technique is presented. A phase shift as high as 20° at 10GHz is achieved using the expansion properties of a piezo-electric ring by applying dc voltage.

通信用毫米波相控阵天线的光束控制

大孔径相控阵天线采用光纤分配网络设计，为MMIC有源T/R模块提供相位和频率参考信号、波束转向和整形控制信号以及数据/跳频信号。给出了38GHz (ka波段)毫米波频率下FO通信网络的实验结果。给出了500MHz-1GHz FO链路的频响平坦度、谐波和三阶互调失真等特性。讨论了间接光注入锁定对38GHz IMPATT振荡器的稳定效果。采用45dB放大增益，锁定范围为132MHz。整个系统调频噪声衰减测量为16dB。该通信链路是通过将数据链路与稳定的LO进行上转换来建立的。介绍了一种新型光纤拉伸技术的真延时移相器。通过施加直流电压，利用压电环的膨胀特性，在10GHz下实现了高达20°的相移。
