Hello,
I am working with the ADRV9009 transceiver and would like to confirm a few points:
-
Is it possible to generate two different RF signals on the two TX paths using a common LO (for example LO = 4.5 GHz), if I perform a digital frequency shift inside the FPGA using an NCO before the DAC?
-
For instance, if one TX path carries a signal centered at 0 Hz (no offset) and the other is shifted digitally by +200 MHz, would the outputs appear at 4.5 GHz and 4.7 GHz respectively?
-
Are there any sample rate or bandwidth limitations I should be aware of for this type of operation?
- Also, how much digital freq shift is possible?
-
-
Regarding device support for duplexing:
-
I understand the ADRV9009 is primarily intended for TDD systems. Do the ADRV9008-1 (RX) and ADRV9008-2 (TX+ORx) devices also support TDD operation, or are they only recommended for FDD use cases?
