This eBook covers some of the technical challenges and solutions for 5G infrastructure and fixed wireless access design along with overviews of the market. Topics include the latest on standards, semiconductor design tradeoffs, advantages for semiconductor and measurement companies, how GaN technology can solve 5G challenges, and how mmWave links will perform for 5G.
Traditionally RF power amplifiers used GaAs technology which has a well behaved and understood performance. Over the past few years GaN technology is replacing GaAs because GaN is more efficient and has a higher power density resulting in higher power MMICs and FETs.
One of the most challenging things about working with millimeter-wave technology is getting accurate measurements. Uncertainty can be introduced at many points during testing, so selecting the right test equipment is an important decision.
