ADL5380 with modulate signal close to DC (DC-100kHz)

Hy everybody,

I'm looking to use the ADL5380-EVALZ with LO frequency f0=1,150 GHz and the modulated signal fm can be go from DC to 100 kHz.

For low modulated signals frequencies, the I or Q output are always at -70 dBm. But the technical sheet didn't mention a low frequency limit of the modulated signal.

Can you help me to solve this issue please.

Kind regards,

Olivier Haas
