Ka-band in satellite communications plays an increasing important role today. However, at higher frequencies, electromagnetic wave absorption increases. At Ka-band frequencies this can lead to service interruptions and performance degradation during rain fades. With high atmospheric losses, conventional fade margin approaches such as adaptive-waveform techniques or adaptive-power control techniques are not sufficient for compensation. For reliable and highly available operations, only site diversity configurations on the ground provide an adequate, fail safe solutions.

There is a wide range of SDRs, from basic to highly complex, that serve a multitude of purposes for a range of applications, that are still being uncovered. Read this article about the various factors for SDR performance and example applications.

The largest collaborative undertaking yet to explore the relic light emitted by the infant universe, Cosmic Microwave Background Stage 4, has taken a step forward with the U.S. Department of Energy’s selection of Lawrence Berkeley National Laboratory (Berkeley Lab) to lead the partnership of national labs, universities and other institutions that will carry out the DOE roles and responsibilities for the effort.
