AMAT 0190-09272定向耦合器是一种四端口网络设备，通常用于信号取样以进行测量和监测，以及信号分配和合成。它可以接入信号发生器、矢量网络分析仪和发射器等射频源与负载之间的传输线，以测量从射频源到负载的射频功率（正向分量），以及从负载反射回射频源的功率（反射分量）。
定向耦合器具有以下特点：
- 定向性：它通常由四个端口组成，其中两个端口用于输入和输出信号，另外两个端口通常接匹配负载。由于其定向性，定向耦合器能够从主传输路径中提取一小部分能量，并将其导向至一个或多个耦合端口。
- 高隔离度：理想情况下，定向耦合器的端口之间具有绝对的隔离度，这意味着耦合器在理想状态下端口之间是绝对隔离的，端口3和端口4之间的耦合因子是相同的，方向性将是无限的。
- 低插入损耗和反射：定向耦合器通常具有极低的插入损耗和反射，这有助于提高信号传输的质量和效率。
- 可配置性：根据不同的应用需求，可以选择具有不同耦合因子的定向耦合器。此外，端口的配置也可以根据需要进行选择，以满足特定的系统需求。
在实际应用中，AMAT 0190-09272定向耦合器可以用于多种不同的场景，如天线测量、信号监测、雷达系统等。它通常与矢量网络分析仪等测试设备一起使用，以实现信号的定向传输、取样、分析和测量等功能。
英文资料
AMAT 0190-09272 directional coupler is a four port network device commonly used for signal sampling for measurement and monitoring, as well as signal distribution and synthesis. It can be connected to transmission lines between RF sources and loads such as signal generators, vector network analyzers, and transmitters to measure the RF power (forward component) from the RF source to the load, as well as the power reflected back from the load to the RF source (reflected component).
Directional couplers have the following characteristics:
Directionality: It usually consists of four ports, two of which are used for input and output signals, and the other two ports are usually connected to matching loads. Due to its directionality, directional couplers can extract a small portion of energy from the main transmission path and direct it to one or more coupling ports.
High isolation: In an ideal situation, there is absolute isolation between the ports of the directional coupler, which means that the coupler is absolutely isolated between the ports in an ideal state. The coupling factor between ports 3 and 4 is the same, and the directionality will be infinite.
Low insertion loss and reflection: Directional couplers typically have extremely low insertion loss and reflection, which helps improve the quality and efficiency of signal transmission.
Configuration: According to different application requirements, directional couplers with different coupling factors can be selected. In addition, the configuration of ports can also be selected as needed to meet specific system requirements.
In practical applications, AMAT 0190-09272 directional couplers can be used in various scenarios, such as antenna measurement, signal monitoring, radar systems, etc. It is usually used in conjunction with testing equipment such as vector network analyzers to achieve directional signal transmission, sampling, analysis, and measurement functions.
