This shows the spectral re-growth seen sending DVB-S when the Mitsubishi RA18H1213G module is driven to about 7 watts output. This is using the standard bias arrangement.
This is the output of the same module when transmitting about 1 watt of DVB-T The rubbish on either side of the signal is due to the problem in the iFFT I mentioned a few days ago. I have not figured out a way around it yet.
