LDMOS FET technology has emerged as the leading technology for high power RF applications, especially for base station power amplifiers for cellular systems. Breakdown voltages of 65 V or higher allow use with a 28 V supply while retaining ruggedness and reliability. This article outlines the characteristics of these devices and describes various methods of biasing to obtain best performance.

During product testing for space and aerospace applications, traceability is a critical concern. Many questions arise when an organization wants to change or evolve their test system policy. How do you track changes? How do you keep your software under control? How do you manage data? When do you go from a single PC to a network? How do your replicate changes on multiple test stations? COM DEV has developed a new common test software platform to address these specific concerns.

This course contains approximately 12-hours of instruction on the fundamentals of microwave filters, couplers, and matching networks. Included is a thorough review of the common types of filter responses and calculations, filter realization, and various methods of filter design, including bandpass, network theory and Kuroda.

Many analysts agree that the continuing growth of Linux signals the beginning of the end of proprietary hardware/software as the sole solution for high-end computing. Increasingly, enterprises that use proprietary platforms such as Sun’s Solaris are seeking lower-cost alternatives that provide equal or better performance without limiting future growth or the range of hardware and software choices.
