| Abstract: | Combined with the design method of step impedance resonator, this paper designs a multilayer band-pass filter under LTCC process. Besides the top and bottom ground plates, the proposed band-pass filter has a three-layer structure in the middle, and the wide-edge coupling is performed between adjacent resonators. The band pass filter has two cavities with a center frequency of about 10 GHz and a passband range of 8. 9 GHz to 11.7 GHz. The band-pass filter effectively reduces the volume, and the total volume is 3.2 mm×1.6 mm×1.7 mm. |
