摘要

本文的目的是将微带带通(BP)和低通(LP)滤波器设计、仿真和集成到一个基于LTCC的多层封装中。本文介绍了一种中心频率为7ghz、带宽约为7ghz的五段微带发夹BP滤波器。2 GHz和微带阶跃阻抗LP滤波器，截止频率为2.5 GHz。本文给出了基于两种不同LTCC衬底(GreenTape 9K7X和GreenTape 951PX)的上述滤波器散射参数(S参数)的模拟和测量结果。本文的重点是研究层间通孔对微带LP滤波器高频性能的影响。本文给出了一种将两种不同类型的滤波器集成在一个多层模块中的可能性，在高频区互不干扰。所开发的带集成微带滤波器的多层结构应作为[1]中提出的I - Q (in -phase Quadrature)解调器的一部分。

Integration of microstrip LP and BP filters to multilayer structure based on various LTCC

The aim of this paper lies in a design, simulation and integration of microstrip Band-Pass (BP) and Low-Pass (LP) filters into one multilayer package based on LTCC. In this article, we introduce five-section microstrip hairpin BP filter with a centre frequency of 7 GHz and a bandwidth of approx. 2 GHz and microstrip stepped-impedance LP filter with a cut-off frequency of 2.5 GHz. The paper presents simulated and measured results of mentioned filters' scattering parameters (S parameters) based on two different LTCC substrates (GreenTape 9K7X as well as GreenTape 951PX). Accent of this article was to investigate the impact of interlayer vias on microstrip LP filters' performances in the high frequency (HF) area. This paper shows a possibility of how to integrated two different types of filters in one multilayer module without mutual interference in HF area. The developed multilayer structure with integrated microstrip filters should be used as a part of I - Q (In-phase Quadrature) demodulator presented in [1].
