[Amps] New SGC Mini Lini Uses Class E Technology

[Bill L. Fuqua]

I have some questions.
Why does the plug-in band module need so much cooling air and what are the drive requirements? 
You realize that this adds to the DAF discussion. Which practically does the same thing.  I have had some nagging issues with the DAF circuit.  One is if you are amlifing AM for example and eleminate the envelope and restore it that would work just fine. But, if you have multiple frequencies of different amplitudes that you clip and then restore the envelope, how does each seperate frequency get assigned it's approprate amplitude?
These last question has nagged me for some time.

Greetings, has anyone else seen the new SGC Mini Lini 500 watt output Linear 
Amplifier using Class-E Technology and Envelope Elimination and Restoration to 
amplify an SSB signal with 90% efficiency? It looks like SGC is the first to 
come out with a working Class-E / EER linear amplifier for the Amateur market. 
The power amplifier and power supply together weigh less than 5 lbs and you 
can hold them in the palm of your hand. The amplifier does need to use plug-in 
modules for each separate ham band but still a real achievement in efficiency 
and power-to-weight ratio. Go to this address to read more about it
