the MOSFET should look like a 1.2 ohm resistor. Keep in mind that’s 120 watts–more power than a common incandescent light bulb. So you are going to need to carry some heat away. The circuit is ...

That’s where builds such as this well-engineered 600W broadband RF amplifier ... using it. While LDMOS transistors aren’t exactly new – laterally-diffused MOSFETs have been appearing in RF ...
