Passive-intermodulation (PIM) performance is essential to the successful operation of many wireless communications systems, although it typically must be tested with a number of fairly high-level test tones.
Signal integrity through interconnects, transmitters and receivers affect product reliability and system performance and has become a major challenge for designers of high speed systems. And the importance to effectively and accurately use Vector Network Analyzer (VNA’s) for time domain and frequency domain measurements has increased....More
As more mobile devices are being equipped with LTE technology, understanding both theory and practical measurement techniques is necessary for everyone from troubleshooting technicians to design engineers....More
Doherty PAs are becoming more common as modulation schemes increase in peak-to-average-power ratio. Using load-pull to optimize a Doherty PA design can lower device power levels and increase the PA design’s efficiency....More
Because measuring RF/microwave power is one of the most commonly used methods of understanding system performance, detailed knowledge of how power measurements are made is key to successfully interpreting measurement results....More
As MIMO devices are increasingly sought to solve throughput demand problem, more antennas are being included in the device design. This complexity is augmenting the value of automated methods for performing MIMO test....More
