摘要
介绍了一种400～520MHz耦合度为-20dB的LTCC多层片状耦合器的设计。该耦合器由两个高耦合系数多层电感相互耦合而成,它的应用频率范围是400～520MHz。用标准LTCC工艺实现的耦合器尺寸仅1.6mm×3.2mm×0.76mm,耦合度-20±2dB,隔离度-35dB,反射损耗小于-20dB。
In this paper,a LTCC(low temperature co-fired ceramic) chip multiplayer coupler is presented.The operation features two coupled multiplayer inductor with higher negative coupling coefficients.The operation frequency of the coupler is 400～520 MH.Its size is only 1.6 mm×3.2 mm×0.76 mm when implemented by a standard LTCC technology.Its coupling is-20±2 dB,the isolation is-35 dB typically and the return loss is less than-20 dB.
