Abstract
the effects of neutron irradiation in GaAs MMICs and small signal FETs were investigated. Carrier concentration and mobility were measured as a function of fluence, doping and channel depth. The individual components of the MMICs were also measured. Device degradation was determined to be the result of a combination of decreases in carrier concentration and mobility in the FETs. Radiation hardness levels based on 20% degradation in gain and drain current were determined.
