HARDWARE FOR RF FRONT-END OF WIRELESS COMMUNICATION

Hardware provides the building blocks for the specified requirements and functions of wireless communication systems. In many defense and satellite systems, devices and circuit designs are aimed at the best performance, although the choice of hardware is often conservative. In the case of wireless communication systems, this conservative approach is somewhat true because of the rapid turnaround in commercial products. In fact, manufacturability and marketability become the drivers for many high volume short-cycle commercial products as many industrial participants in this study like Dr. J. Golio of Rockwell emphasized. However, in looking at the future beyond the G3 and even G4 environment, research concerning hardware needs to be advanced in a steady and accelerated pace. This includes not only devices and circuits, but also enabling process technology and design methodologies. This is because the performance of future wireless systems critically depends on hardware capability. Dr. Golio mentioned that the faster, smaller, lighter and cheaper philosophy still holds. It is also true that research methodologies for hardware may need to be modified.
