A microwave pulse compressor (MPC) consisting of an iris, a straight waveguide section, and a T-junction can be used in order to convert a long pulse with lower power to a shorter pulse with a higher power. A significant compression gain can be achieved, provided that the system is designed precisely. The duration of the compressed pulse is proportional to the cavity length, thus imposing a constraint on the development of mobile systems. In this work, we present the circuit/transmission-line-based design methodology that we follow in order to fold the cavity (while retaining the same electrical length) by using T-junction turns. For example, we design a 1.3-GHz folded compressor and compare its performance to the corresponding one of a straight-cavity compressor. The 3-D full-wave simulations with CST Studio Suite and experimental measurements with the developed compressor confirm the accuracy of the proposed design methodology.

使用小尺寸波导腔设计微波脉冲压缩机

可以使用由虹膜、直波导部分和 T 形接头组成的微波脉冲压缩器 (MPC)，以便将具有较低功率的长脉冲转换为具有较高功率的较短脉冲。如果系统设计精确，则可以获得显着的压缩增益。压缩脉冲的持续时间与腔长成正比，从而限制了移动系统的发展。在这项工作中，我们提出了我们遵循的基于电路/传输线的设计方法，以便通过使用 T 形结匝折叠空腔（同时保持相同的电气长度）。例如，我们设计了一个 1.3 GHz 折叠式压缩机，并将其性能与相应的直腔式压缩机进行了比较。
