Re: Difference between "power amplifier" and "
an amplifer is an amplifier is an amplifier...
the terms you describe are more or less informal
If you tell me an audio amplifier, i think an amplifier that works around 20Hz to 20 kHz. If you say VHF amplifier, I think 30MHz to 300 MHz since that is the definition of VHF. If you say power amplifier, I think > 1watt.
For your project, I think a 1 watt VHF class C RF amplifier is what you need.
You asked about an audio amplifer IC earlier. You would not use this between your transmitter and antenna. It won't work at this high a frequency (100MHz).
