  This invited paper details some of the hardware modelling and impairment
analysis carried out in the EU mmMAGIC project. The modelling work includes
handset and Access Point antenna arrays, where specific millimeter-wave
challenges are addressed. In power amplifier related analysis, statistical and
behavioural modelling approaches are discussed. Phase Noise, regarded as a main
impairment in millimeter-wave, is captured under two models and some analysis
into to the impact of phase noise is also provided.
