Product Number: AD9699
Dear Sir,
Our customer is using AD9699 under the following conditions.
- Sampling Clock: 2560MHz
- NCO Frequency: 640M
- DDC: 8
- 2560M / 8 = 320M sampling
- MUX Gain Correction: 6dB
- FIR Filter: All path, 6dB Gain Correction
- DC Offset Calibration: ON
- Input Frequency: 1790MHz
The FFT output is as follows
- Signal (-130MHz) -46.7dBm
- Mirror Image(130MHz) -112.1dBm
Do you have any idea to reduce this Mirror Image? Please advise.
Regards,
Koide
Corrected typo in the subject, AD969 -> AD9699.
