Applications
GaN-on-SiC and LDMOS-ready substrates power the high-efficiency amplifiers driving 5G massive-MIMO and mmWave base stations.
4H-SiC MOSFET substrates enable higher switching frequencies and lower losses in EV traction inverters and on-board chargers.
GaN-on-SiC and semi-insulating GaAs substrates support the high-power, high-frequency amplifiers used in radar and satellite communication systems.
SiC and FZ-silicon power substrates improve conversion efficiency in solar inverters, wind power converters, and grid-scale storage systems.
RF-SOI and GaAs substrates form the switches, LNAs, and power amplifiers packed into modern smartphone RF front-end modules.
GaN and SiC power devices reduce switching losses and shrink passive component size in industrial motor drive and power supply designs.
