5G is now and what’s next?
5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, as a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030.

One of the primary purposes of a gate driver is to enable power switches to turn on and off faster, improving rise and fall times. Faster switching enables higher efficiency and higher power density, reducing losses in the power stage associated with high slew rates. However, as slew rates increase, so do measurement and...

Stepper motors are mostly driven in open loop mode. Timing of the step pulses is defined by the controller, the motor is supposed to follow without loosing synchronism. Stepper motors are in fact natural positioning devices which do not require position feedback. The drawback of their design are important iron losses when...

Lithium-ion batteries, like other battery types, are subject to a process of wear and tear during charging and discharging due to chemical changes.
Without battery balancing, the weakest cell in a multicell battery always determines the capacity of the entire system. However, since individual cells age differently,...

Vector Network Analysers (VNA) are gaining popularity in the Signal Integrity community as Time Domain Measurement and Analysis tools.
VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs...

In addition to voice connectivity, digital cellular wireless networks such as GSM and its enhancement, GSM-EDGE, can now provide increased data speeds up to a (theoretical) limit of 384Kbps. Third generation mobile networks, such as CDMA2000 and WCDMA or UMTS (Universal Mobile Telecommunications Standards) and TDSCDMA...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field...

The demands for faster wireless access and lower latency are continuously increasing. To meet these demands and to drive new use cases, regulatory bodies around the world open up spectrum in the 6 GHz band for unlicensed use. This new spectrum allows the Wi-Fi 6 standard, IEEE 802.11ax, to unfold its full power. It will...
