What are the Differences Between GaN and GaAs RF Power Amplifiers?
Posted by MSE Supplies on
The need for high power in the VHF, UHF, and microwave bands has led to transistors that can easily supply tens to hundreds of watts at RF frequencies to 10 GHz and beyond. Most of these devices are made with gallium arsenide (GaAs) or gallium nitride (GaN). MSE Supplies is a leading supplier of high quality crystal substrates, including GaAs and GaN.

Pulsed RF power device markets up to 4GHz: GaN, SiC, Si and GaAs based technologies
Posted by MSE Supplies on
The high-power pulsed RF semiconductor device market is primarily driven by several specific sub-segments. They are as follows: Avionics Sub-1 GHz Radar L-Band Radar S-Band Radar The end-customers for these devices are primarily the worldwide air traffic control system both airborne and ground-based, and commercial and military radar systems. Markets for pulsed RF power devices up to 4GHz will show continued growth over the next five years to more than $250m by 2021, despite current economic and political turmoil, forecasts a report by ABI Research. MSE Supplies is a leading supplier of GaN and SiC crystal substrates. While their association...

Transition metal impurities can kill the efficiency of GaN-based LEDs
Posted by MSE Supplies on
Using advanced first-principles calculations, University of California, Santa Barbara (UCSB) researchers have demonstrated the mechanism by which transition metal impurities – iron in particular – can act as nonradiative recombination centers in nitride semiconductors. The work highlights that such impurities can have a detrimental impact on the efficiency of light-emitting diodes (LEDs) based on gallium nitride or indium gallium nitride. This is a schematic illustration of Shockley-Read-Hall (SRH) recombination due to iron in GaN. Iron is a deep acceptor with a defect level (black line) close to the GaN conduction band (green). The charge density corresponding to this localized level is...

GaN Power Business will Grow at an 86% Annual Growth Rate and Reach $280M by 2021
Posted by MSE Supplies on
The GaN power market, however, remains small compared to the gigantic $335 billion silicon semiconductor market. MSE Supplies is a leading global supplier of GaN single crystal substrates with low dislocation density and uniform surface quality. The past year has been an exciting one for the gallium nitride (GaN) power business, with the 600V GaN now commercially available and GaN power IC has finally debuted, opening new market perspectives for GaN companies. No longer a hazy picture, market research firm Yole Developpement is expecting the GaN power business to reach $280 million in 2021, with an 86% CAGR between...
