This paper aims to discuss the filter structures which constitutes a planar inductor, capacitors using microstrip lines and make it tunable taking the advantage of LTCC multilayer design. Investigations of passive multilayer filter structure using low-temperature co-fired ceramic (LTCC) for microwave and radio frequency application is studied. A roadmap for performance and process parameters to...

Dispersion, impedance matching and resolution characteristics of an isotropic three-dimensional flat lens (“superlens”) are studied. The lens is based on cubic meshes of interconnected transmission lines and bulk loads. We study a practical realization of the lens, based on the microstrip technology. The dispersion equations that have been previously derived, are verified with full-wave simulat...

This paper presents an efficient modeling method, based on the microstrip lines theory, for the coupling between a substrate backplane and a device contact. We derive simple closed-form formulas for rapid extraction of substrate parasitic. We use these formulas to model spiral inductors as important substrate-noise sources in mixed-signal systems. The proposed model is verified for the frequenc...

DESIGN, ANALYSIS, AND CONSTRUCTION OF AN EQUAL SPLIT WILKINSON POWER DIVIDER Logan J. Berens, B.S. Marquette University, 2012 The Wilkinson power divider is a well known device in the RF/microwave community used for splitting or combining signals. It is composed of simple transmission lines and a resistor, and takes advantage of the properties of quarterwavelength transmission line sections to ...

In this paper, a compact and high isolation microstrip diplexer is designed for broadband and wireless local area network (WLAN) application, simultaneously. The bandpass filter (BPF) for broadband channel is formed by three-coupled-line structure and two short stubs with different size loaded in 50 Ω feed lines, and the BPF for WLAN channel consists of two coupling quarter-wavelength resonator...
