The WLAN7205C from NXP reduces the number of components in the Wi-Fi RF signal chain.

Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions.

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…

An amplifier design from 1936 gets a revival by reducing power consumption in cellular radios.

CES isn’t just about the latest consumer gadgets, there’s something for engineers, too.

5G Technology World spoke with Analog Devices’ Nitin Sharma on the massive MIMO technology deployed in 5G base stations from NEC.

RF power amplifiers consume lots of energy, which is a concern associated with 5G. Envelope tracking helps reduce power consumption but has tradeoffs.

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…

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.

The SKY5805-11 RF front end from Skyworks adds a PA, RF switches, couplers, and filters to handsets, data cards, and M2M devices.
