摘要：

The model for a compact bandpass filter which has multi-section structure and equivalent elements of package is proposed in this paper. With six vertical via-holes and three planar coupled lines, a multi-section coupled line is available. There are wide upper stopband and multi transmission zeros in the proposed design. This device is implemented in a low temperature co-fired ceramic substrate with thin thickness and shows good rejection with 20 dB rejection level that up to 4.4 x f0. The design also performs co-simulation with SiP model and shielding metal around the device to evaluate the total performance. The EVM measurement in system is available as well. The simulation and measurement results are in good agreement results.
