Hi Ricardas,
Thanks for the quick answer. A couple of followup questions :
You should see 2xLO, 4xLO ... as well.
Oh really ? Mmm, I couldn't see those. I guess they're much lower than
the odd harmonics and were buried in the noise floor.
On the TX side these can be
reduced by RF filter/duplexer. RX LPF will filter them out on the RX side.
Yes, I know how to get rid of them. Unfortunately designing a front
end that can programmably filter those for the whole range of the LMS
(like in a broadband SDR), it's not easy :p
So I was wondering if you had any data on the typical / worst case
values for those so I can know exactly how good a pre-filtering I need
to have on the input.
Cheers,
Sylvain
