摘　　要：介绍了一种基于90°电桥芯片的和差器的设计原理、封装测试方法以及实测结果。针对小型化设计、测试的难点进行攻关,在低温共烧陶瓷(LTCC)基板表贴电桥芯片,并在基板内部引出走线至基板表面,形成测试端口;利用微组装技术实现小型化高集成设计方案。在此基础上设计封装壳体,实现芯片气密封装,提高工程应用可靠性。根据组件实测结果,驻波比小于1.8,幅度一致性优于±0.8 dB,相位一致性优于10°,质量为35 g。The encapsulation principle, design method and measurement results of a miniaturized comparator is introduced in this paper. The difficulties of miniaturization and measurement are tackled.A bridge chip is attached on the surface of the Low Temperature Co-fired Ceramic(LTCC) substrate, and the wire is led out from the inside of the substrate to form a test port on the surface of the substrate.Design scheme of miniaturization and high integration is realized based on micro assemble technology.The package shell is designed to realize the airtight package of the comparator and improve the reliability of engineering application. According to the measurement results of the module, the standing wave ratio is less than 1.8, the amplitude consistency is better than ±0.8 dB, the phase consistency is less than 10°, and the mass is 35 g.
