Cool project! Congrats

Rx/TX isolation?

Typical image rejection (dB)?

Does it support hardware level timestamping to align tx and rx samples through soapy?

Tx/Rx isolation is about -35dB to -40dB depending on the Tx/Rx polarization selection. The QEC image rejection is about -50dBc in Rx, and about -40dBc in Tx (one-time cal, without background cal enabled). The Tx and Rx are perfectly synchronized. This allows you to easily do things like near-field 4x4 MIMO radar: https://www.youtube.com/watch?v=gVqESemU_AI
