定向耦合器选型|Kyocera京瓷低插入损耗小型薄膜射频定向耦合器，适用于高频无线系统
京瓷集团（KYOCERA）旗下的AVX推出的薄膜射频定向耦合器，主要得益于其掌握的多层薄膜技术，所以AVX设计出来的定向耦合器尺寸小，还具有优越的高频性能以及便于自动化生产、安装的坚固结构。另外，AVX薄膜定向耦合器工作频率带宽宽，支持大部分高频无线系统如移动通信、卫星电视接收机、GPS、车辆定位系统以及无线局域网。
Kyocera的子公司AVX薄膜定向耦合器从尺寸来分包含三种微型尺寸，分别为：0402, 0603, 0805，具有高定向性、低插入损耗、高隔离度、表贴型等特点，主要用来平衡无线系统中的放大器和信号分布。目前，AVX已经把薄膜定向耦合器产线扩张到高定向性产品线，包括优化后针对WIFI频段的高定向性LGA Wi-Fi 耦合器。AVX高定向性耦合器以及3dB 90°耦合器工作频率范围为：400MHz~6GHz。
Kyocera的子公司AVX薄膜定向耦合器主要分为三类：定向耦合器（Directional Couplers ）、高定向性耦合器（High Directivity Couplers）、以及3dB 90°耦合器（3dB 90° Couplers）。图1列出了三种耦合器的一些基本参数如最大工作温度、工作频率、功耗等级等。
图1 三种耦合器基本参数
薄膜定向耦合器分为CP0603 SMD、CP0805 SMD两种类型，薄膜高定向性耦合器分为CP0402系列、CP0603系列、CP0402P紧凑系列、宽频带以及WiFi频带系列，薄膜3dB 90°耦合器分为：DB0603N系列、DB0805系列。
SMD型薄膜定向耦合器:
CP0603/CP0805 SMD型薄膜定向耦合器采用ITF (Integrated Thin-Film) TECHNOLOGY（集成薄膜技术），这是耦合器尺寸能够做到很小的关键。CP0603/CP0805 SMD类型薄膜定向耦合器支持的工作频率范围：800MHz~3GHz，特征阻抗：50Ω，工作/存储温度范围：-40ºC ~ +85ºC，功率等级：3W，结构坚固，高度低于同类产品。此外，CP0603/CP0805表贴型耦合器均100%通过质检，质量可靠，兼容回流焊、波峰焊等自动化焊接技术。
宽频带高定向性耦合器CP0402W2700FNTR，工作频率范围为：700-2,700MHz，耦合系数：24±2，插入损耗仅0.3dB，定向性能达到20dB。WiFi频带系列高定向性耦合器型号有：CP0302P5425ENTR、CP0302A5425ENTR、CP0402Q5425ENTR 、CP0603Q5425ENTR。顾名思义，WiFi频带高定向性耦合器工作频率范围即WiFi工作频段（2.4G/5G频段），应用于WiFi频段内的耦合器提供三种标准尺寸：0302, 0402, 0603。高定向性耦合器中的宽频带耦合器与CP0402系列、CP0603系列、CP0402P紧凑系列的主要区别在于其工作频段宽 ，而其他系列工作频率范围都是针对某一系统（AMPS/GSM/E-GSM/PDC/PCN/PCS/PHP/DECT/Wireless LAN等）内的频带。
3dB 90°耦合器:
3dB 90°耦合器分为：DB0603N系列、DB0805系列。其中，DB0603N系列采用的是LGA封装，DB0805系列采用的是SMD封装，两个系列功率等级皆可以达到10W，主要用于平衡无线系统中的放大器和信号分布。
最后帮大家总结一下，AVX薄膜定向耦合器采用LGA封装的有：DB0603N、高定向耦合器所以系列，其他系列采用SMD封装。二着区别在于，LGA封装尺寸更小，焊接以及散热特性也更好。
