5G Technology World and EE World present our first 5G handbook, digital edition.
Wi-Fi 6E front end integrates amplifiers and switches
The WLAN7205C from NXP reduces the number of components in the Wi-Fi RF signal chain.
Size, weight, power, and heat affect 5G base station designs
Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions.
The challenges of building a 5G base station
To meet 3GPP specifications, a 5G New Radio (NR) implementation must meet demanding processing requirements and RF capabilities. Compared to LTE, this results in a need for higher performing, more flexible 5G NR hardware. Looking at 5G’s technical challenges, we see the frequencies and spectrum supported now include a sub-6 GHz range, FR1, with bandwidths…
How Doherty Amplifiers improve PA efficiency
An amplifier design from 1936 gets a revival by reducing power consumption in cellular radios.
CES 2021: The engineering perspective
CES isn’t just about the latest consumer gadgets, there’s something for engineers, too.
What’s inside Rakuten Mobile’s open RAN radio?
5G Technology World spoke with Analog Devices’ Nitin Sharma on the massive MIMO technology deployed in 5G base stations from NEC.
Envelope tracking improves power amplifier efficiency
RF power amplifiers consume lots of energy, which is a concern associated with 5G. Envelope tracking helps reduce power consumption but has tradeoffs.
How to calculate RF power amplifier efficiency
5G brings higher data rates and a need for more efficient power amplifiers. Understand and calculate a PA’s efficiency. Radio communication systems steadily improve data rates and overall system performance. With that higher performance comes increasing pressure on power consumption. A recent industry report [Ref 1] concluded that power consumed by a typical 5G base…
Microwave amplifier pumps out 20 W
The SAM100 from Rohde & Schwarz lets RF component manufacturers test devices on the engineering bench or from a rack and operates from 2 GHz to 20 GHz.
