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.
Front-end module supports 3G, 4G, 5G
The SKY5805-11 RF front end from Skyworks adds a PA, RF switches, couplers, and filters to handsets, data cards, and M2M devices.
Power transistors drive 5G cells
The single QPD0005 and dual QPD0405 power transistors from Qorvo provide the power needed to drive cellular antennas.
Antenna brings 5G to IoT devices
The Lepida S4L054 from Antenova mounts on a PCB like any other SMT component.
5G test moves into production
5G Technology World’s video interview with NI’s David Hall looks at 5G ICs coming off the production line and what’s coming next.
IMS 5G Summit: Design challenges remain (part 2)
Part 2 continues the theme of power and efficiency in amplifiers, adding upload links, fixed access, and open RAN.
IMS 5G Summit: Design challenges remain (part 1)
Just because 5G is rapidly rolling out doesn’t mean everything works and it’s time to move on. Indeed, the design challenges are just beginning, as this two-part series from IMS 2020’s 5G Summit shows.
