Design Techniques and Considerations for GaAs and GaN RF and Microwave Devices
there have been many advancements in rf compound semiconductors in the last few years. gaas designers have developed higher performance products to compete with gan and with the mainstreaming of gan technology, some companies are taking it to the next level with higher power levels than ever imagined before. from improvements in performance and levels of integration to reliability and packaging, this ebook examines many of these new developments and will update you on several advancements in high frequency compound semiconductor technology.
Starwave: Shaping the Future of 5G mmWave OTA Testing
learn the pros and cons of various 5g ota test systems and newly introduced starwave, a compact, accurate and flexible far-field ota testing solution for 5g devices. this compact and flexible, dual polarized, wideband plane wave generator turn-key test system was developed to improve testing efficiency and optimize time-to-market of 5g devices. the ebook covers the challenges of 5g ota testing and compares compact antenna test ranges with plane wave generator based systems highlighting the advantages of each.
Antenna and Beamforming Design and Simulation
this ebook is a compilation of phased antenna and beamforming technology articles along with contributions from comsol on simulation techniques and examples of new antenna arrays and beamforming techniques to help you learn about the tradeoffs and design options in this fast developing area. the articles cover fully digital phased array radars, modeling and simulation examples, new array beamforming technologies, 28 ghz beamsteering antenna array simulation and other related topics.
5 Ways to Address 5G Interference Issues
as the rf spectrum becomes more crowded, the chance for interfering signals greatly increases as frequency bands become very close to each other and sometimes even overlap. there are many techniques from filtering to spectrum sharing to frequency cancelation. this ebook has five articles that cover various aspects of interference. the first takes a look at the wi-fi or 5g question – do we need both and how they use the same frequencies in some cases. the second article looks at a new self-interference cancelation method for co-location of radio transceivers so they can share the same frequency band. the third looks at a growing technology for 5g called dynamic spectrum sharing that allows lte and 5g signals to use the same frequency band. the next article is a short discussion about how the unlicensed bands may become a key factor in the rollout of 5g. the last article takes a look at 5g mmwave filtering and the challenges to designing good filters at these higher frequencies.
