Microwave characterization of microstrip lines and spiral inductors in MCM-D technology

Mixed-Potential Volume Integral-Equation Approach for Circular Spiral Inductors

“…Employing cylindrical coordinates , we next adopt the quasi-1-D approximation by neglecting the components of and variations of in the radial -and vertical -directions inside the rings for (8) where is the azimuthal unit vector (Fig. 4).…”

Fabrication of a band-reject filter using dielectric-supported air-gapped microstriplines

“…This development of MMICs has increased the demand for transmission lines that enable the propagation of microwave and millimeterwave signals. In microwave and millimeter-wave integrated circuits, conventional planar transmission-line structures, such as microstrip lines and coplanar waveguides (CPWs), are widely used at present [1,2]. However, the geometric structure of these conventional transmission lines has dielectric loss and dispersion characteristics due to the semiconductor substrate supporting the transmission line, which degrades circuit performance in the highfrequency range.…”

“…Digital television (DTV) broadcasting has been operational in many countries, and it is expected to replace all conventional analog TV broadcasting in the near future [1]. Since DTV broadcasting can provide a super-sharp high-definition television (HDTV) program, interactivity service, and data service, it has become very attractive for mobile communications devices, such as laptops and portable computers, to be equipped with a DTV receiver in order to enhance their multimedia functions.…”

Micromachined RF passive components and their applications in MMICs

“…MMIC researchers have devoted long hours to alleviate these difficulties, not only at the circuit level [1,2], but also at the process technology level [3][4][5][6]. Component performance degradation due to the substrate can be reduced by either lowering the shunt capacitance or using high-resistivity substrates.…”
