Abstract :
High voltage, field plate based GaAs MESFETs have great potential for providing high performance MMICs with low cost, high reliability, and immediate production capability required by today´s applications. With high voltage operation comes the potential under nonideal operating conditions for premature burnout. Robustness becomes a serious concern for any high voltage application. High Voltage MSAGTM (HVMSAGTM) MESFETs exhibit high reliability and excellent robustness against 10:1 VSWR load mismatches at 30V when junction temperatures are restricted to less than 350degC. Void free die attach and low MESFET thermal resistance are important factors for enhancing device robustness.
