Hello,
I have a question about harmonic distortion of ADL5565 from our customer.
It's about figure-21 of the datasheet(Rev.G)
(He is using VPOS=3.3V and single-end input)
The HD3 is about 12dB degraded relative to figure-17 at F=250MHz and Av=5.3dB.
(At Av=10.3dB and 13dB, the HD3 is not degraded relative to figure-17)
And HD2 is about 20dB degraded relative to figure-17 at F=250MHz and Av=5.3dB.
The customer feel wonder that the degradation of HD2 is too large than HD3.
Would you teach me the reason of this ?
Best regards,
y-suzuki
