Based on LTCC technology,this study proposed a second-order bandpass filter,which is often used as a important part of passive components.As for the design of filters,it is a common microwave band-pass filter with the centre frequency of 2.45 GHz and bandwidth of 100 MHz,while the transmission zeros frequencies are 1.75 GHz and 4.40 with a size of 3 mm×3 mm×0.7 mm.This filter consists of six layers of capacitors and inductors.The perfect agreement of electromagnetic simulation with circuit simulation indicates good working mechanism both in miniaturization and frequency performance.
