If you’ve been following 5G technical developments for the last few years, you probably know that 5G encompasses more than just faster download speeds. You may have heard about low latency (1 msec or less) and the applications that makes possible. Now, 5G is in deployment and the hype far exceeds reality. The hype, of…

Mobile devices have evolved from basic analog phones to digitally enabled smartphones that fit in the palm of your hand. Voice communications are still part of the mix, but voice calls are handled by converting the voice signal from analog to digital and transmitting it digitally. This means that mobile wireless systems are focused on…

Qualcomm’s Snapdragon X60 5G modem builds on its two 5G predecessors—the X50 and X55—by adding sub-6 GHz and mmWave carrier aggregation, plus other features. According to Qualcomm, the 5 nm process used to fabricate the X60 provides higher power efficiency into a smaller footprint. Additional features include: 5G frequency-division duplex (FDD) and time-division duplex (TDD)…

To minimize issues from standing waves, engineers have long used Faraday rotation isolators that let forward-traveling signals pass to the load while attenuating reverse-traveling signals such as reflections. Higher frequencies, however, bring a new set of problems such as insertion loss that Micro Harmonics claims to have solved with its mmWave isolators. The series consists…
