Amplifiers and filters are essential components in microwave systems. An amplifier is used to increase the signal strength, and it is usually cascaded by filters for frequency selection or harmonic rejection [1]–[3]. Their functionalities require a precise design of the individual parts as well as the way in which they are connected. The common approach is to make individual components with a system impedance that is usually {50}\Omega{.}{50}\Omega{.} A generic example of the filters and amplifier in a generalized receiver is shown in Figure 1(a).

集成滤波器放大器：综合回顾


放大器和滤波器是微波系统中的重要组件。放大器用于增加信号强度，通常与滤波器级联以进行频率选择或谐波抑制[1]-[3]。它们的功能需要对各个部件及其连接方式进行精确设计。常见的方法是制作系统阻抗通常为 {50}\Omega{.}{50}\Omega{.} 的各个组件。通用接收器中滤波器和放大器的一般示例如图 1（a ）。
