Multichannel phase coherent transceiver system with GNU Radio...
summary
A production-ready multichannel phase-coherent transceiver with a GNU Radio interface demonstrates a working 4 channel 200MHz system built from two ADRV9009 chips, an HMC7044 clock distributor, and JESD204B links that deliver deterministic latency and RF LO phase synchronization across power cycles. The implementation scales via clock-tree and multi-chip sync, exposes hierarchical GNU Radio blocks on GitHub for averaged-phase and cross-correlation validation, and measures stable, repeatable inter-channel phase offsets.
