Spotlight On Massive MIMO/Beamforming
Beamforming For An 8x8 Planar Phased Patch Antenna Array For 5G At 28 GHz

In this example, an 8x8 planar antenna array creates narrow beams capable of scanning large sectors in front of the antenna. The example focuses on displaying typical simulation results for beams and possible plots of coverage from the full array and combinations of sub-arrays.

Overview Of Multi-Channel Signal Generation Applications With R&S SMW200A

The R&S SMW200A is a vector signal generator designed with the ability to simultaneously generate up to eight independent signals from one single instrument for use in complex applications such as MSR, carrier aggregation, MIMO, or other enhanced interference scenarios. 

ADI’s RF Front-End Family Enables Compact 5G Massive MIMO Network Radios

In the quest for higher data rates to support a variety of wireless services and different transmission schemes, system designers face higher circuit complexity but must meet similar budgets for size, power, and cost. 

What’s So “Massive” About Massive MIMO?

As the list of mobile services available grows, technologies that provide these services must evolve in order to meet this demand while simultaneously improving the overall cost structure to consumers and service operators. Massive MIMO is a key element in 5G cellular networks.  

Industry Insights
COTS Software-Defined Radio For 5G Development

The latest SDR products offer SoC solutions with integrated I/O, ARM processors, and large FPGAs that include intellectual property (IP) for accessing, routing, and processing digital data. 

The Rectangular Waveguide Cut-Off Frequency

The cut-off frequency is the frequency above which the waveguide offers minimum attenuation to the propagation of the signal. Frequencies below the cut-off frequency are attenuated by the waveguide. The dominant mode in a waveguide is the propagation mode with the lowest cut-off frequency. 

Passive RF And Microwave Beamformer Networks

Early beamforming network designs were typically fixed-beam architectures, although newer configurations include complex adaptive beamforming networks. This presentation reviews the origins of the technology and offers several example circuit topologies of passive microwave beamformers.
