Introducing EM.Cube® Pro 2012 ...
EM.Cube Pro integrates a number of simulation engines within a common user interface, sharing the same CAD modeling environment and same data visualization tools. For example, you can:
• Analyze a highly directional communications link in a high multipath urban environment.
• Model finite-sized antenna arrays on the transmitter and receiver sides.
• Design RF, microwave and millimeter wave circuits and passive devices.

 New Heights In Amplifier Efficiency
By Paul Kruczkowski, Editor
Improving efficiency has long been and will continue to be a fundamental challenge in amplifier design for wireless infrastructure. Higher efficiency base stations require less power and heat dissipation, which reduces operating costs. Today’s base stations utilize Doherty amplifier designs that boast 45% to48% efficiency, but as impressive as that may be, more than half of the power applied is still lost or dissipated. However, I recently learned about a new supply modulation technique that could soon lead to new heights in base station efficiency. |

RF Switch Matrix Basics: Configuring And Verifying With Simulation Tools
This is the first in a series of guest columns by Bob Alman of SenarioTek.
RF and microwave switch matrix solutions play a key role in a variety of test systems. At SenarioTek, we design and configure signal routing solutions that are often unique to a specific application. Over the years, we have found some basic steps that help facilitate the design process and ensure that the finished product meets the needs of the test system. This column covers what I believe are the most important initial steps in the process.
