[amsat-bb] HELAPS info?

[Claudio Martins <ctpm@xxxxxxxxxxxxxxx>]

  Hi folks

  I've been using google & friends all morning, and been unable to find any 
real deep information about HELAPS (High Efficiency Linear Amplification by 
Parametric Synthesis) technology used in the Phase 3 satellite transponders.
All references found seem to know what the HELAPS acronym means, but none 
seems to contain any implementation discussion... ;-)

So any info or any links to a paper or similar would be apreciated. 
Thanks in advance for your attention

Best regards, 73
