The S2DR 1000 from Augustus Aerospace Company is a Space-Grade Dual Transceiver Software Defined Radio (SDR) that operates from 70 MHz to 6 GHz. This SDR offers dual software defined high performance RF transceivers which can be customized to the unique mission-critical requirements of scientific and military missions for LEO CubeSat deployment. It is a space-optimized SDR that provides rapid development of powerful and flexible small satellite payloads.
The SDR consists of a Xilinx Zynq-7030 processor with dual ARM 9 cores, Kintex-7 FPGA, and 256 KB RAM, 4 GB DDR3 RAM, voltage regulator, 24 MHz reference, Analog Devices’ dual RF transceiver, baluns, phase-locked loop, 10 MHz reference (optional), and interfaces. It isolates the wideband transceivers and utilizes the processor to implement demanding custom signal processing applications. The SDR requires a DC supply from 9 to 28 V and consumes less than 7 W of power.
On the Tx side, the S2DR 1000 integrates dual programmable transmit paths with adjustable level control and monitoring while on the Rx side, it supports dual 12-bit ADCs with output sample rates of up to 65 MSPS and programmable FIR with decimating filters operating over a bandwidth of 54 MHz. It includes a 40 MHz VCTCXO clock that locks to an external 10 MHz reference and 1 PPS time reference. This SDR can be controlled using UART (debug and auxiliary control and discrete control), JTAG, GPIO, and micro-USB 2.0 (test) interfaces. It is available in an enclosure that measures 9.0 x 9.6 x 2.7 cm and has SMA connectors. This space-grade SDR is ideal for space-based RF sensors, tactical radio repeaters (space), multi-channel/multi-protocol radio communications, programmable mission data transponders, and precision time and frequency applications.
