铁氧体限制器是一种如果两个或更多个RF载波彼此间隔几个兆周，则具有独立地限制它们的特性的装置。这种特性在通信卫星中作为多址接入工具或用于最小化干扰信号的影响可能具有实用价值。导言部分介绍了该装置及其在商业或军用通信卫星中的限制作用和操作模式。白皮书的正文总结了为确定设备的通信性能而进行的测量。具体地，给出了稳态和动态带宽、一个和两个调频载波的限制作用、相位线性度和两个调频载波之间的串扰的测量结果。该装置的测量性能与由简化分析模型预测的性能符合得很好。测量发现，该设备对于单个宽带调频信号基本上是无失真的。在存在两个载波的情况下，性能的限制因素是相干串扰。
The ferrite limiter is a device which has the property of independently limiting two or more RF carriers if they are spaced by several megacycles from each other. This property may have utility in communication satellites as a multiple access tool or for minimizing the effects of jamming signals. The introductory section describes the device, its limiting action, and mode of operation in a commercial or military communications satellite. The body of the paper summarizes the measurements taken to determine the communications performance of the device. Specifically, measurements covering the steady state and dynamic bandwidth, the limiting action for one and two FM carriers, the phase linearity, and the crosstalk between two FM carriers are presented. The measured performance of the device was in reasonable agreement with performance predicted from a simplified analytic model. Measurements found the device to be essentially distortionless for a single wideband FM signal. With two carriers present, the limiting factor of performance was found to be coherent crosstalk.
