一种新型高抑制微型LTCC低通滤波器
A novel miniaturized LTCC low-pass filter with high rejection
摘要
Abstract
Driven by the demand for device miniaturization and integration,a filter was realized in a three-dimensional package with dimensions of 1.6 mm×0.8 mm×0.6 mm using a low-temperature co-fired ceramic(LTCC)multilayer stacking process.Five sets of lumped elements were embedded within the package.By judiciously exploiting the parasitic effects among the elements,i.e.,the magnetic coupling between inductors and the resonance between inductors and parasitic capacitances,two transmission zeros were introduced.This design simultaneously reduced the filter volume and enhanced the out-of-band rejection.After fabrication and measurement,the filter achieved an insertion loss of less than 1.0 dB across the DC-470 MHz passband,an out-of-band rejection greater than 41 dB at 800 MHz,and a far-out rejection greater than 22 dB at 2000 MHz.A good agreement between the simulated and measured results was obtained.关键词
