My customer are designing new FIR filter (in FPGA) because FIR performance in AD9371 doesn’t meet their repeater requirement.
For this , they wants to bypass FIR filters in AD9371 like below picture
1. - They want to bypass TFIR/ RFIR. Is it possible?
- If it possible, how to bypass TFIR/ RFIR?
- If they do the bypass TFIR/RFIR, is the delay of transmit path & receive path reduced?
2. - If they can’t do bypass TFIR/RFIR, how to control the coefficient of Filters?
- How to extract the coefficient of Filters in AD9371?Filter
- Zero IF기 fiducially, Passband: 0~49.2MHz, Stopband: 50.8MHz, Stopband Attenuation: Over 50dB
Please advise me.
