Which ports on the RX and TX do the three frequency bands (800MHz, 2.4GHz and 5.5GHz) are physically connected to? PortA to 5.5GHz? PortB to 2.4GHz? etc?
AD9361 and AD9364 operate from 70MHz and 6GHz.
All Tx and Rx ports support the full operating frequency range.
If you can, use Rx port A for higher frequencies. Rx ports B and C roll off a little faster than Rx port A frequency response.
