STQ-2016Z Reliability Qualification Report

XII. Junction Temperature Determination

One key issue in performing qualification testing is to accurately determine the junction

temperature of the device. Sirenza Microdevices uses a 3um spot size emissivity

corrected infrared camera measurement to resolve the surface temperature of the device

at the maximum operational power dissipation. The results are displayed below for the

STQ-2016Z device running at operational current of Id= 80mA, a device voltage of 5V,

and lead temperature of 85°C.
