I have made a X14 Multiplier with SRD, the base freq is 57.55M. The X14 multiplier works well, the phase noise loss about 23dB, almost without any additional loss. But I have output spectrum like attached photo, why that happens?
I guess maybe:
1. The Amplifier I used is in saturated status. For driving SRD, I have to push power higher.
2. Maybe the noise floor of the amplifier is high. But almost none vendor issue the noise floor of amplifier, how can I know it?
The amplifier I used is Mini's PMA5452 and ERA-4SM+.
Thanks in advance.
