摘要

解决了与宽带、高衍射效率相控阵布拉格电池相关的基本设计问题。还讨论了获得最佳结果所需的关键制造步骤。TRW已经制造并测试了1-GHz带宽(f/sub c/=2.5 GHz)， 2-GHz带宽(f/sub c/=2.0 GHz)和2-GHz带宽(f/sub c/=3.0 GHz)的GaP纵向模式Bragg蜂窝。结果包括衍射效率(30%/RF瓦，1 ghz带宽)(8%/RF瓦，2 ghz带宽)、两音三阶互调产物和频率响应。

Design, fabrication and characterization of wideband high diffraction efficiency phased array Bragg cells

The fundamental design issues associated with wideband, high-diffraction-efficiency phased-array Bragg cells are addressed. Also discussed are the key fabrication steps necessary to obtain optimal results. TRW has fabricated and tested 1-GHz-bandwidth (f/sub c/=2.5 GHz), 2-GHz bandwidth (f/sub c/=2.0 GHz), and 2-GHz-bandwidth (f/sub c/=3.0 GHz) GaP longitudinal-mode Bragg cells. Results presented include diffraction efficiency (30%/RF watt, 1-GHz-bandwidth) (8%/RF watt, 2-GHz-bandwidth), two-tone third-order intermodulation products, and frequency response.<>
