Chestnut
Chestnut: High-Performance 4 Rx / 4 Tx Software Defined Radio
Chestnut is a high-performance software defined radio (SDR) platform providing 4 receive and 4 transmit radio chains, 500 MHz of instantaneous RF bandwidth per channel, 16-bit converters, and a tuning range from near DC to 9 GHz.
Each radio chain can be independently controlled or configured to share a common local oscillator for applications requiring improved phase coherency and stability across channels. Four 40GBASE-R interfaces provide up to 160 Gbps of digital backhaul for transferring high-bandwidth IQ data between the SDR and host system.
Chestnut combines wideband RF performance, FPGA-based signal processing, precise timing, and high-speed digital interfaces in a compact 2U platform designed for applications including radar, spectrum monitoring, RF recording and playback, GPS/GNSS, wireless communications, electronic warfare, test and measurement, and other advanced RF systems.

Key Capabilities
500 MHZ INSTANTANEOUS BANDWIDTH
Each receive and transmit radio chain supports up to 500 MHz of instantaneous RF bandwidth, enabling wideband signal capture, generation, monitoring, and processing across all four channels.
PHASE-COHERENT OPERATION
Radio chains can share a common local oscillator to improve channel-to-channel phase coherency and stability for applications including radar, direction finding, beamforming, and other coherent RF systems.
4 RX / 4 TX RADIO CHAINS
Four receive and four transmit channels support multi-channel and full-duplex SDR applications. Radio chains can be independently tuned and controlled for applications requiring simultaneous operation across multiple frequencies.
160 GBPS DIGITAL BACKHAUL
Four 40GBASE-R interfaces provide up to 160 Gbps of aggregate digital throughput for transferring high-bandwidth IQ data between Chestnut and host processing, recording, or storage systems.
FPGA SIGNAL PROCESSING
The Intel Stratix 10 FPGA SoC provides substantial programmable resources for Per Vices DSP, filtering, triggering, digital up/down conversion, data processing, and other application-specific functionality directly on the SDR.
INTEGRATION & CUSTOMIZATION
Chestnut can be integrated into new or existing RF systems with support for custom FPGA functionality, software, interfaces, filtering, timing, synchronization, and other application-specific requirements.
