摘　　要：利用低温共烧陶瓷叠层工艺设计了一款具有带通响应的紧凑型低温共烧陶瓷巴伦滤波器。微型化的巴伦采用Marchand Balun结构和LTCC的立体集成结构,巴伦内部带状线利用宽边带状线结构,采用一种螺旋化方式,减小巴伦的体积。经过电磁仿真优化和实际加工滤波器的测试结果表明:滤波器在2 400 MHz～2 500 MHz插入损耗小于3.2 dB,不平衡端驻波比小于2.0,相位差为180°±10°。A low-temperature co-fired ceramic Balun filter with a bandpass response was designed using a low-temperature co-fired ceramic laminate process.The miniaturized Balun uses the three-dimensional integrated structure of the Marchand Balun structure and the LTCC(Low Temperature Co-fired Ceramic).The Balun internal stripline utilizes a broad-side stripline structure and uses a spiraling method to reduce the volume of the Balun.After the electromagnetic simulation optimization and actual processing filter test results show that:the filter insertion loss is less than 3.2 dB in 2 400 MHz^2 500 MHz,unbalanced end VSWR is less than 2.0,and the phase difference is 180°±10°.
