描述了高功率速调管、耦合腔行波管 (TWT) 和混合管，所有这些都利用微波腔作为基本电路元件。这些放大器用于通信、雷达、电子对抗和其他应用，功率级别从几百瓦到兆瓦，频率从超高频以上，特别适合高平均功率。通常可实现 30 至 60 dB 的高增益，带宽通常在 1-30% 范围内。描述了基本的操作理论，以及设计考虑因素和系统接口信息。提供了典型的管设计和数据。讨论了最新的发展，包括高效技术（达到 75%）、带宽改进、周期性聚焦和光束控制电极。大多数基本设计技术都已得到很好的发展，重点正在转移到细节性能特性的改进上，例如增益和相位分辨率纹波、噪声以及对工作电压和电流的敏感性。
High-power klystrons, coupled-cavity traveling-wave tubes (TWT's), and hybrid tubes, all of which utilize the microwave cavity as the basic circuit element, are described. These amplifiers are used in communications, radars, electronic countermeasures, and other applications at power levels from a few hundred watts to megawatts, at frequencies from ultrahigh frequency on up, and are particularly suited for high average powers. High gain, 30 to 60 dB, is normally achieved, and bandwidth usually lies in the 1-30-percent range. Elementary theory of operation is described, together with design considerations and systems interface information. Typical tube designs and data are presented. Recent developments are discussed, including high-efficiency techniques (to 75 percent), improvements in bandwidth, periodic focusing, and beam control electrodes. Most of the basic design techniques are well developed, and emphasis is being shifted to improvements in the detailed performance characteristics such as gain and phase resolution ripples, noise, and the sensitivities to operating voltages and currents.
