This Standard applies to all types of MMIC (monolithic microwave integrated circuit) based on III-V compound materials for RF applications (i.e. frequency range greater than or equal 1 GHz). The requirements for the procurement of components in die form are defined. It is not within the scope of this Standard to address packaged MMICs and discrete microwave components, these are dealt with in the relevant ESCC specification (ESCC 9010 and ESCC 5010). This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.
