I want to build / design an RF amplifier that can boost the signal from an AMT-MW207 kit.

Design goals:

• Boost the signal a couple of watts
• AM signal
• 525 - 1605 kHz baseband range

I've been searching for RF amplifier designs but many of them are too big (10's of Watts), or are hard to implement. It's been difficult trying to find something that can instruct me clearly. I'll have to take into account things like impedances and the like.

I have an electronics background, so if you can only point me towards a book or other resource, even that would be helpful.

I'm going to be checking out 'Experimental Methods in RF Design', hopefully it can point me in the right direction.
