Description
技术领域Technical field
本发明涉及无线通讯设备的技术领域，具体为一种铁氧体的检测装置。The invention relates to the technical field of wireless communication equipment, specifically a ferrite detection device.
背景技术Background technique
在现有的无线通信系统中，发射机是有一个重要的组成部分，由功率放大器(PA)、耦合器、环形器/隔离器、连接器、双工器及天线等部分组成，其中耦合器用于链路的相关监测功能，环形器或隔离器(环形器与功率吸收负载组合构成隔离器)用于保护功放管，连接器将输出信号传输到双工器。在无线领域都是类似的设计，但是随着无线通信发展，对小型化的要求越来越高。In the existing wireless communication system, the transmitter is an important component, consisting of a power amplifier (PA), coupler, circulator/isolator, connector, duplexer and antenna, among which the coupler is For the related monitoring function of the link, a circulator or isolator (the combination of a circulator and a power absorption load forms an isolator) is used to protect the power amplifier tube, and the connector transmits the output signal to the duplexer. Similar designs are used in the wireless field, but with the development of wireless communications, the requirements for miniaturization are getting higher and higher.
微波铁氧体又称旋磁铁氧体，在高频磁场作用下，平面偏振的电磁波在铁氧体中按照一定方向传播时，偏振面会不断绕传播方向旋转的铁氧体材料。具有铁磁共振线宽小、自旋波共振线宽大、在低频段，饱和磁化强度低和磁晶各向异性常数小、介质损耗低、稳定性高等性能。采用电子陶瓷工艺，热压烧结或氧气氛中烧结制造而成，主要用于制作毫米波铁氧体器件。Microwave ferrite is also called gyromagnetic ferrite. Under the action of a high-frequency magnetic field, when plane-polarized electromagnetic waves propagate in a certain direction in the ferrite, the polarization plane will continue to rotate around the propagation direction of the ferrite material. It has properties such as small ferromagnetic resonance line width, large spin wave resonance line width, low saturation magnetization and small magnetocrystalline anisotropy constant in the low frequency band, low dielectric loss, and high stability. It is manufactured using electronic ceramic technology, hot pressing sintering or sintering in an oxygen atmosphere. It is mainly used to make millimeter wave ferrite devices.
在现有技术中，环形器/隔离器均需要用到铁氧体，铁氧体目前的是粉料混合、压铸、烧结、机加工、刷银层制作而成。所以行业中一般都是采用测量外形尺寸、平面度、粗糙度、密度、介电等参数间接的评估铁氧体的旋磁性能，这种方法不能精准的评估铁氧体的性能，故环形器/隔离器的生产厂家还需对铁氧体进行进一步检测，从而评估铁氧体的性能。In the existing technology, circulators/isolators require the use of ferrite. Ferrite is currently made by mixing powder, die-casting, sintering, machining, and brushing with a silver layer. Therefore, the industry generally uses the measurement of dimensions, flatness, roughness, density, dielectric and other parameters to indirectly evaluate the gyromagnetic performance of ferrite. This method cannot accurately evaluate the performance of ferrite, so the circulator /The manufacturer of the isolator needs to conduct further testing of the ferrite to evaluate the performance of the ferrite.
现有隔离器的生产工厂收到铁氧体后，同一批次随机抽选10片，组装5个隔离器，测试隔离器的S参数，以此评估铁氧体的性能。此方法可以直接看到被检测铁氧体是否可以满足要求。但是由于隔离器工艺比较复杂，有十几道工序，一般要花费1-2小时才能得到结论。并且结论也比较容易受到其他因素的影响，比如5个产品磁铁在相应腔体的位置不一致，电路之间有偏差等都会对检测结果造成影响。After the existing isolator production factory receives the ferrite, it randomly selects 10 pieces from the same batch, assembles 5 isolators, and tests the S parameters of the isolator to evaluate the performance of the ferrite. This method can directly see whether the ferrite being tested can meet the requirements. However, because the isolator process is relatively complex, there are more than a dozen processes, and it usually takes 1-2 hours to get the conclusion. And the conclusion is also easily affected by other factors. For example, the positions of the five product magnets in the corresponding cavities are inconsistent, and there are deviations between circuits, etc., which will affect the detection results.
为此环形器/隔离器的生产厂家急需一种可以快速检测铁氧体性能的装置，从而使得铁氧体的检测快速可靠稳定。For this reason, circulator/isolator manufacturers urgently need a device that can quickly detect the performance of ferrite, so that the detection of ferrite can be fast, reliable and stable.
