技术问答

隔离器是一个有单向传输特性的二端口器件，又称单向器。是一种单向传输电磁波的器件，当电磁波沿正向传输时，可将功率馈给负载，对来自负载的反射波则产生较大衰减，这种单向传输特性可以用于隔离负载变动对信号源的影响。隔离器在规定的方向上传输仅有很小的损耗，而在另一个方向上传输就有很大的损耗（隔离）。隔离器由磁化的铁氧体片、传输线和输入输出连接器组成。

（隔离器构件图）

隔离器的应用：

1、可作为源和负载的隔离；

2、可用于功率放大器；

3、可提高功率合路系统的隔离度。

隔离器原理：

隔离器是由铁氧体制成的各向异性的微波无源的器件。铁氧体是一种黑褐色的陶瓷，当微波频率的电磁波通过铁氧体时，导电损耗是很小的。更重要的是, 它是一种非线性各向异性磁性物质，它的磁导率随外加磁场而变，即具有非线性；在加上恒定磁场以后，它在各方向上对微波磁场的磁导率是不同的，就是说其具有各向异性的。由于这种各向异性，当电磁波从不同的方向通过磁化铁氧体时，便呈现一种非互易性。利用这种效应，便可以做成各种微波铁氧体元件，其中隔离器就是常用的微波铁氧体元件之一。

在实际应用中，根据使用情况不同，可分为各种性能不同的的隔离器如：同轴隔离器，带线隔离器，表贴隔离器，宽带隔离器，双节隔离器，高功率隔离器，微带隔离器，波导隔离器等。每种分类的隔离器都各有异同特点，下面就单双节隔离器各异同特点进行探讨一下：

单节隔离器：顾名思义，单节隔离器即为单节的隔离器，也是比较常用的隔离器，其按连接形式不同可分为同轴、带线、表贴隔离器。

双节隔离器：双节隔离器也可称多节隔离器，即为两个或多个单节隔离器构成，其按连接形式不同也可分为双节/多节同轴隔离器、双节/多节带线隔离器。

单双节隔离器的区别与联系：

1、从外形尺寸上看，双节隔离器尺寸比单节隔离器要大，如同一频段的隔离器，可以看成双节隔离器是由两个单节隔离器合成的，如图为优译的2-4GHz单双节隔离器尺寸图：

单节隔离器：UIYBCI3234A2T4SF

双节隔离器：UIYBCI6434A2T4SF

2、从指标性能上看，双节隔离器的隔离度是叠加的，因而其具有高隔离度的特点，故双节隔离器也可称高隔离度隔离器，如图是2-4GHz单双节隔离器的指标对比，所以在应用当中，需要有大隔离的则可选用双节隔离器。

3、单节隔离器的插损比双节隔离器要小，双节隔离器的隔离度提上去了，但随之损耗也会变大。因此，在没有要求要很大隔离度的情况下，可选择单节隔离器，其具有插损小，体积小等特点。

4、单双节隔离器在指标性能上，虽然隔离度跟插损两者相差较大，但其驻波比是不变的。

【产品】可实现40dB以上高隔离度的优译双节隔离器

隔离度是衡量隔离器功能最重要的一个指标，隔离度是衡量一个信号泄露到其他端口的功率与输入功率之比，单位dB。常见的隔离度大概是20dB，有时候客户在应用中需要40dB甚至以上的隔离度时，我们会建议用两个隔离器接在一起以达到高隔离度的效果，通常我们称为双节隔离器。本文优译主要列举了客户常需型号的双节隔离。

【应用】优译隔离器与环行器的应用，可提高功率合路系统的隔离度

环行器与隔离器是一类微波铁氧体器件，通过铁氧体控制微波信号的传输。环行器和隔离器提供了一个单向的传输通路，允许射频信号只朝一个方向通过(低损耗)，而在其他方向则产生很大的损耗(隔离)。本文主要介绍优译的环行器和隔离器的应用。

【产品】隔离度最高达50dB的双节隔离器UIYCDI9648A，尺寸为96×48x24mm

优译（UIY）推出的UIYCDI9648A双节隔离器，尺寸96×48×24mm，具有高隔离度优势。隔离度是衡量一个信号泄露到其他端口的功率与输入功率之比，单位dB，是衡量隔离器功能最重要的指标之一，常见的隔离度大概是20dB。而UIYCDI9648A双节隔离器隔离度最高可达50dB（根据具体型号不同，范围在32dB～50dB）。此外，UIYCDI9648A支持双节甚至三节，以实现高度隔离。
