The Kestrel software-defined radio (SDR) is a Zync Ultrascale and MPSoC SDR development kit. Its compact 2x2, MIMO-capable transceiver is optimized for SWaP-constrained applications and consists of two circuit cards — the Kestrel Processor and the Kestrel Radio. The Kestrel SDR design is based on the Raptor SDR Development Kit and shares the same radio IC, the same family of AMD SoC, and the same embedded-Linux operating system.

The Kestrel RF transceiver is MIMO-capable from 70 MHz to 6 GHz. The configurable transmit path supports 70 MHz to 6 GHz, and the receiver performance is enhanced by a four-band preselector and wideband low-noise amplifier (LNA).
