hi
thanks alot
Hi. I seem to be having some issues where the right side of some figures and equations seem to be cut-off. I used Chrome and Internet Explorer thinking that maybe the browsers rendered the .pdf incorrectly, but this cut-off appears on both copies.
Anyone else having this issue?
I am as well.
Thanks for posting this free tutorial… I myself am just getting into the industry, and TWTA’s are something I’ve had difficulty wrapping my head around. Thanks!
Hi,
Very informative tutorial. One thing about non-linear behavior is unclear to me however, hope you can give me a short answer.
If you look at an ideal clipping device, the output signal will graduately become a block-shape as the input-sine amplitude increases. My question now concerns interpretation of “saturated output power” (0 dB IBO and 0 dB OBO) of the TWTA:
1) Is it the power of the entire block-shaped output signal (so including harmonics)?
2) Is it the power of the fundamental harmonic in the block-shaped signal?
There is a 0.9 dB difference between the two interpretations, but I’m not sure how to interpret this correctly.
Best regards,
Jeroen
