宽频带移相天线阵需要一些特殊的元件。例如,用来激励移相天线阵的行波管在管子之间要求有非常一致的电气特性。如对相位的直线性,增益的平坦度,输出功率的峰值与频率的关系等规格在很宽的工作频带内有很严的要求。在“美国电子学设计”杂志1963年7月19日第 Broadband phase-shifted antenna array requires some special components. For example, traveling wave tubes used to excite phase-shifted antenna arrays require very consistent electrical characteristics between the tubes. Such as the linearity of the phase, the flatness of the gain, the peak output power and frequency of the specifications and other specifications in a very wide operating band has very strict requirements.
