恒达微波波导魔T功率分配器 合成器说明书
1.6功率分配器/合成器【产品简介】恒达微波提供一系列高性能的波导魔T 、功分器、合成器产品。
在魔T 的H 臂或E 臂接上负载，则可制成魔T 功率分配器或合成器。
波导魔T 具有如下特点：平衡臂两端对称；从E 臂输入的信号会在平衡臂两端等幅反相输出，H 臂隔离；从H 臂输入的信号会在平衡臂两端等幅同相输出，E 臂隔离；从平衡臂任一端输入的信号在E 臂和H 口等分输出，而对应平衡臂另一端隔离。
因此魔T 具有的对口隔离、邻口3dB 耦合及完全匹配的特点，使之在微波领域获得了广泛应用,尤其用在单脉冲雷达和差比较器、雷达收发开关、功率分配/合成、混频器及移相器等场合。
【型号描述】波导魔T ，波导管型号BJ100，材料为铝（材料为铜时缺省）。
产品类型：波导魔TH D - 100 W M T A波导管型号：B J 100恒达微波材料：铝【产品类型】类型代码含义类型代码含义WET 波导ET 接头WHT 波导HT 接头WMTPC 波导同相功率合成器WMTPD 波导同相功率分配器WMT 波导魔TWSWC 波导90°功率分配器/合成器(窄边耦合)；I\U\XY\YU 型WTWC波导90°功率分配器/合成器(宽边耦合)；I\U\XY\YU 型1.6.1波导ET 接头、波导HT 接头这两种器件在微波系统中常用作功率分配/合成元件。
波导ET 接头可以将E 口输入的信号在平衡臂两端等幅反相输出，反之，在平衡臂两端等幅反相输入信号则在E 口合成输出；波导HT 接头可以将H 口输入的信号在平衡臂等幅同相输出，反之，在平衡臂两端等幅同相输入信号则在H 口合成输出，但是ET 、HT 接头是不匹配的器件，只对其E 口或是H 口进行单端口匹配。

4.2 EJB模型
EJB是一个由Java语言开发的，可在多层的分布式环 境中部署的服务器端软件组件,是J2EE技术的核心。 EJB的核心思想是将商业逻辑与底层的系统逻辑分开， 使开发者只需关心商业逻辑，而由EJB容器实现目录 服务、事务处理、持久性、安全性等底层系统逻辑， 并且可创建具有动态扩展性的服务器应用。
会话Bean（维护会话）：模拟商务过程，代表调 用它的客户程序所要完成的工作，执行商务逻辑、 商务规则、算法和工作流程，如电子商店的购物 车。——由容器管理
消息驱动Beans：结合了会话Bean 和 JMS的消息 监听器的特性, 可在企业平台中处理同步或异步消 息，如电子商店的公告栏。 ——由容器管理

J2EE相关技术
Servlet ：驻留在Web服务器上的 Java 类，用于接 收来自Web浏览器的Http请求，进行处理后返回 HTTP 响应信息。 JSP：Java 服务器页面允许程序员将 Servlet 代码 写入基于文本的文档中。这些页面与 HTML 页面 类似，只是它们还含有 Java 代码。 当第一次请求一个JSP页面时，Web服务器需要先 把该JSP页面编译为一个Servlet，为请求提供服务。 在客户请求JSP页面时，服务器就会处理Java代码， 然后返回Html页面给浏览器。

JavaBean技术
JavaBean是基于Java的组件模型，类似于Microsoft 的COM组件。 通过JavaBean可以实现代码的重复利用，扩充Java 程序的功能，快速生成新的应用程序以及使程序更 容易维护。 JavaBean比EJB小得多，常规javabean主要是在开 发时可重用，在JVM中运行，不是可部署的组件。 企业bean指在运行时可重用，而且必须在EJB容器 的控制之下运行 。

什么是EJB
Sun公司发布的文档中对EJB的定义是：EJB是用 于开发和部署多层结构的、分布式的、面向对象的 跨平台的Java应用系统的组件体系结构。
EJB规范说明定义了Java的服务器端组件模型。
EJB是在容器里执行的，Sun公司也发布了EJB容 器的规范，EJB可以在任何符合规范的容器中运行， 容器其实就是给EJB提供服务的。
从本质上讲，EJB容器是客户端程序和Bean之间看 不见的中间人。 28

部署描述
部署描述声明一个指定的Bean应该如何使用中间 件，而不是编写代码使用中间件。 部署描述可用来描述下列要求：
⑴Bean的生命周期管理 ⑵持久性要求
