A Multiband Bandstop Filter Using a Single Ring Resonator for a Wireless Access Communication System

A novel multiple bandstop filter (MBSF) with compact size and low insertion loss is proposed and fabricated. This filter is composed of a cell of a spurline and a section of coupled lines with a rectangular ring resonator. The center frequencies of the...
Wireless communication systems, such as cellular mobile communication systems, wireless local area networks (WLAN) and short-range communication systems (Bluetooth), provide convenient communication services in modern society. In an airplane, when the onboard wireless communication services are provided, many other systems may be used simultaneously. Compact equipment that supports multimode/multiband...

Narrowband Vector Intermodulation Measurements

This novel measurement technique determines accurately the magnitude and phase of nonlinear scattering parameters of nonlinear devices. For these measurements, it is necessary to extend a conventional vector network analyzer with an external phase refe...
Almost all electrical elements and components have more or less nonlinear characteristics: they generate harmonics, mixture and intermodulation (IM) products. In order to prevent these effects from affecting the performance or even damaging the system functionality, a nonlinear characterization is necessary to obtain high end results. In this context,...

The Best of Saad

Many of us grew up in the afterglow of Ted Saad's accomplishments. I first met Ted at the Dallas symposium in 1982; the MTT Society of which he was a founding member was celebrating its 30th birthday. Ted was a key figure in MTT's growth and culture: h...
On "Conferences and Exhibitions" Usually we reserve the technical sessions at [various conferences] for assessing what the new ideas are and where the technology is going. I believe it is equally important to find out at least two more things, the first is whether the new ideas can be...
