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...

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,...

A Wideband Millimeter-wave Coaxial to Rectangular Waveguide Transition Structure

Most current adapters use additional fixtures such as tuning screws to achieve the desired transmission response. These tuning components often present challenges in design. In this article, dielectric photonic band gap (PBG) structures are introduced ...
The coaxial to rectangular waveguide transition is one of the most important devices used in microwave and millimeter-wave circuits. Especially at millimeter-waves, a waveguide-to-coaxial adapter is one of the most often used components for efficient electromagnetic wave transmission and high power handling. Although many types of adapters are available...

Tackling the Mixed-signal Testing Challenges of SDR

Software-defined radios (SDR) utilize a combination of FPGAs, DSPs and analog/RF designs to achieve the radio’s system performance. The mixed-signal nature of these SDR designs can introduce system integration testing complexities when the baseband hardware and RF hardware are integrated and tested together. This testing complexity presents itself because...

Pushing Radar Designs to the Limit with Highly Realistic Signal Scenarios

In the development of next-generation radar and electronic warfare (EW) systems, typical test scenarios include simulations such as low-observable signals mixed with ground clutter and environmental interferers. Addressing these demanding scenarios requires an arbitrary waveform generator (AWG) or signal-scenario generator (SSG) that has two key attributes. The first is...

Simplifying and Improving Advanced-technology MIMO Receiver Testing

Multiple-In, Multiple-Out (MIMO) antenna techniques promise to deliver exceptionally high data rates over new wireless technologies such as LTE and LTE-Advanced. However, the increase in attainable data rates brought about by MIMO technology is based on taking advantage of several channel characteristics that were inconsequential to legacy technologies. These...
