The die is manufactured using 0.18 µm gate length
pHEMT Technology. The MMIC uses gold bond
pads and backside metallization and is fully
protected with Silicon Nitride passivation to obtain
the highest level of reliability. This technology has
been evaluated for Space applications and is on the
European Preferred Parts List of the European
Space Agency.
