摘要
主要讨论了T/R组件中承担提取、供给监测信号任务的弱耦合定向耦合器的研制。为了节约空间,这种定向耦合器及其50Ω负载被制作在LTCC(低温共烧陶瓷)多层基板内部。该定向耦合器的输入、输出及耦合端均设置有接地共面波导式的测试端口,可以使用空气共面探针测试台和微波矢量网络分析仪进行测试。
This paper presents an approach to develop a directional coupler which picks up and provides the indication signal in X-band T/R modules. The coupler and an embedded 50 Ω resistor terminal are designed into LTCC （ Low Temperature Co-fired Ceramic） multilayer substrate of the X-band high-integrated encapsulated module. The input, output and couple ports are coplanar waveguide style for measured with probe station and microwave VNA.
