AFE7225: Can 160MHz BW signal be handled by AFE7225? _ Continued

Part Number: AFE7225

Hi,

In recent post I asked if AFE7225 can handle 160MHz signal.

The answer was "if it is instantaneous bandwidth of 160MHz, ii can not"

Here my application is 160MHz is the IQ data(I+, I-, Q+, Q-) coming from RF down converter from RF to BB, and its signal BW is 160MHz. Would this be categorized to your mentioned iBW?

Thanks,
Tiejun

Hey Tiejun,

Yes. What you described for your application is what is classified as the instantaneous bandwidth & the AFE7225 cannot handle an instantaneous bandwidth of 160MHz.

Thanks

Hey Tiejun,

Max RX IBW = 62.5 MHz

Max TX IBW = 125 MHz

Thanks
