We are selling S-band HPAs for satcom applications.
A customer needs to obtain key RF characteristics of the S-Band HPA, specifically the wideband frequency response of carriers as a function of output level to understand out of band energy levels.
They gave the following example, but I am not sure how that can be done without a modulated input signal.
- 1 Msymbol carrier at 0 dB, 3dB, 10 dB OBO (wrt 200 W output)
- 5 Msymbol carrier at 0 dB, 3 dB, 10 dB OBO (wrt 200 W output)
- 10 Msymbol carrier at 0 dB, 3 dB, 10 dB OBO (wrt 200 W output)
Will the P1dB and OIP3 answer their question? If not, would you please advise on what is needed to be performed and how?
