RF POWER MOSFET
N-CHANNEL ENHANCEMENT MODE
The ARF300 is a N-CHANNEL RF power transistor in a high efï¬ciency ï¬angeless package.
It is designed for high voltage operation in narrow band ISM and MRI power ampliï¬ers at
frequencies up to 45MHz. The transistor is well matched to the ARF301 P-CHANNEL RF
power transistor making the pair well suited for bridge conï¬gurations
