The low-power QFP4526 and high-power QFP4568 bring switches, filters, and amplifiers to Wi-Fi 8 (802.11ax) designs. Wi-Fi 6 (IEEE 802.11ax) access points, routers, gateways, customer-premise devices, and IoT devices need amplifiers to boost signal power to its final levels. The QFP4526 and QFP4568 front-end modules from Qorvo operate at 3.7 V and 5 V power…
EM simulation is crucial to 5G wireless design
5G Technology World spoke with Jonathan Oakley of Dassault Systemes on how the company’s electromagnetic simulation software helps engineers design and evaluate antennas for smartphones and IoT devices.
Open RAN unlocks network functions
In a video interview, Analog Devices’ Nitin Sharma explains the company’s involvement with open RAN and the concept of a functional split. Open radio access networks are all the talk at the network — as opposed to the wireless — side of 5G. While most of the talk surrounds the disaggregation of network functions, the…

BBox: Beam steering for mmWave testing
The BBox from TMYTEK lets you control a signal’s amplitude and phase under software control. Use it to test antennas, phones, small cells, and measure material properties when subjected to mmWave signals.
Digital modulation basics, part 2: QAM and EVM
In Digital modulation basics, part 1 we examined the concept of quadrature modulation and signal generation. We showed a common block diagram for generating a quadrature signal (Figure 1). There is a corresponding receiver block diagram to extract the Inphase (I) and Quadrature (Q) components of the signal (Figure 2). The signal is converted to…
X60 Modem aggregates mmWave and sub-6 GHz carriers
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)…
