摘　　要：文中提出了使用集成无源器件(IPD)技术的0.745～1.3 GHz微型宽Wilkinson功率分配器。集成无源器件技术可将分立无源器件集成到衬底中,并提高Q值和系统集成度。通过使用LC阻抗变换来恢复常规微带线来实现尺寸减小。通过这种方式,可以在不牺牲性能的情况下大大降低电路尺寸。该功率分配器的插入损耗为0.2,隔离度为-20 dB,回波损耗为20 dB。采用IPD工艺技术,该产品具有较高的可靠性,较好的应用前景。A 0.745-1.3 GHz miniature wide Wilkinson power divider using IPD(integrated passive device)technology is proposed.The integrated passive device technology can integrate discrete passive components into the substrate and thus improve Q-value and system integration.Size reduction is achieved by using LC impedance transformation to recover conventional microstrip lines.In this way,the circuit size can be greatly reduced without sacrificing performance.The power divider has an insertion loss of 0.2,an isolation of -20 dB,and a return loss of 20 dB.By using IPD process technology,the product has fairly high reliability and very good application prospects.
