Enhancing 5G infrastructure and resilience 

ORanGaN is developing new manufacturing processes and packaging solutions to create 5G components such as Monolithic Microwave Integrated Circuit Chips (MMIC). 

The manufacturing processes developed ORanGaN will focus on:

  • The design and development of the MMIC (Viper RF)

  • Manufacturing of the chip (INEX Microtechnology)

  • Testing and characterization of the technology (Compound Semiconductor Applications Catapult CSA Catapult)

  • Electronics and packaging of the chip (Custom Interconnect Ltd).
