The NXP MRF300AN is an LDMOS RF power transistor delivering 300 W output across 27 MHz to 250 MHz, with a typical gain of 28 dB at 50 V test voltage. This is a current-production, ROHS3-compliant device, still actively manufactured.
The MRF300AN covers 27 MHz to 250 MHz and delivers 300 W output at 50 V test voltage, with a typical gain of 28 dB.
Yes, at 300 W output the device dissipates significant heat. The TO-247 package tab must be mounted to a heatsink with good thermal interface — plan for a substantial thermal solution in your BOM.
