am working on the project topic as above but
I must be truthful to you, am a novice and I need
help to start this project.
I need any workable schematic that will give me the output as in the topic
and if possible necessary material to aid the theory work. please I will appreciate if quick response is sent. thanks

 

Spend an hour or two reading the eBook located at the top of every page on this site.

Start by learning the Class A amplifier. Then the Class C amplifier. It will be easier to get to 50 Watts by cascading stages rather than doing it in one stage.

BTW in my experience VHF is from 30-300 MHz. Is that about what you expected?
