Ham radio 600W broadband HF amplifier

*Dan Maloney KC1DJT* writes on Hackaday about a 600W broadband HF amplifier
using affordable LDMOS devices

Typically, amateur radio operators use the minimum power needed to
accomplish a contact. That’s just part of being a good spectrum citizen,
and well-earned bragging rights go to those who make transcontinental
contacts on the power coming from a coin cell. But sometimes quantity has a
quality all its own, and getting more power into the ether is what the
contact requires. That’s where builds such as this well-engineered 600W
broadband RF amplifier come into play.
