The thermal resistance of the NPT1015 is 2.1°C/W, which is among the lowest in the industry in this power class, claims Nitronex. Devices from multiple wafers were mounted in a 50 ohm test circuit tuned for CW operation at 2.5 GHz. The devices were operated at rated output power and subjected to a 15:1 VSWR at all phase angles. They showed 100% survivability with no measurable change in saturated output power.
The NPT1015 incorporates significant design improvements that increase breakdown voltage and lowers thermal impedance. Fully-qualified NPT1015 transistors are now available from stock to 12 weeks.
