Spotlight On GaN/GaAs/SiGe Solutions
Why GaN Is 5G’s Super ‘Power’: A Series
 

While some feel gallium nitride (GaN) is still a relatively new technology, many can't dispute how it's advanced to the head of the class. GaN is a technology on the cusp of dethroning silicon LDMOS, which has been the material of choice in high-power applications.

mMIMO Enables 5G, GaN On SiC Enables mMIMO
 

Massive multiple-input multiple-output (mMIMO) significantly increases the number of antennas on a single array. The emergence of gallium nitride (GaN) on high-thermal conductivity silicon carbide (SiC) substrate has enabled mMIMO implementation and thus 5G.

GaN Breaks Barriers — RF Power Amplifiers Go Wide And High
 

The increasing demand for higher data rates in telecommunications and higher resolution in industrial systems is pushing the frequency of operation higher for their supporting electronics. Many systems operate over a wide frequency, so increased bandwidths are a common request for new designs. 

Why Gallium Nitride (GaN)?

Gallium nitride (GaN) technology's ability to support high frequency, wide bandwidths, and high-power density make it invaluable in any market requiring high performance in a small form factor. This article compares GaN to other semiconductor technologies.
