Designed for pulsed and CW applications operating in the 2,400 to 2,500MHz frequency range, the 500W BLC2425M10LS500P LDMOS RF power transistor has been announced by Ampleon. Suitable for use in a wide range of cooking RF energy applications, the BLC2425M10LS500P has an excellent high-power to footprint ratio as it delivers 500W CW from a single SOT1250 air cavity plastic package.

With its 67% efficiency, it has a high performance, within this frequency range and power level. Such high-efficiency characteristics will keep the required cooling capacity to a minimum while also ensuring low energy consumption and operating costs of the end-equipment. The transistor also exhibits excellent ruggedness by being able to operate with a VSWR 10:1 load mismatch through all phases, further simplifying the system design and protection circuitry.

The integration of the BLC2425M10LS500P into the application is simplified by the integrated input and output pre-match.
