Abstract
In the design of C band LTCC band-pass filter, since the resonator uses integrated IC and lumped elements use LTCC thick film, its Q value is low and size is relatively large in C band, so in the designing aspect, distribution parameters resonance unit with transmission line structure is the main consideration. Distributed parameter broadside coupled resonator unit, since its coupling coefficient is high, is particularly suitable to designing broadband filter. According to the requirements of filter, we synthesize the coupling coefficient and external Q value of filter through circuit and then realize C band filter with broadside coupled resonator unit using LTCC multilayer technology.关键词
