Testing Modern Radios

Designers have long sought to improve the performance and resiliency of radio communications. Several techniques are now being employed to ensure efficient communications across the chaotic radio spectrum. Chief among them are software-defined radios (SDRs), which enable software to dynamically control communications parameters such as the frequency band used, modulation type, data rates, and frequency hopping schemes...

Technical Overview: Portable PIM Analyzer

A better and more reliable method to determine the quality of construction of cables built on site, or the interconnection of these cables, or the performance of individual components, is to perform a PIM measurement. This can determine if joints are stabilized and secure, clean, and moisture free. The IMT and iQA family of portable PIM analyzers from Summitek provide an effective tool for performing these measurements...

Product Overview: WiMAX Components For Next-Generation Wireless

The newly ratified IEEE 802.16e standard allows manufacturers to begin introducing products for mobile applications. These products will allow users to maintain high speed connectivity in slow speed mobile and portable (devices stationary, but capable of moving within a coverage area) environments. This presents opportunities for M/A-COM solutions over all the common WiMAX frequency bands...
