Abstract : A theoretical analysis using two-tone simulations and practical measurements of low frequency memory impact on third order intermodulation (IM3) on HBT as well as HFET power amplifiers is carried out. A particular emphasis is placed on the thermal origin for the HBT case and electrical origin for the HFET case of these low frequency nonlinear phenomena.
