Red Pitaya STEMlab 122.88-16 SDR Kit Basic

Red Pitaya STEMlab 122.88-16 SDR Kit Basic is tailored for HF+50MHz SDR & RF applications that requires DAQ systems with high precision. The 122.88-16 SDR features improvements based on feedback received from HAM radio operators & research laboratories. The new device comes with two 16-bit ADCs, 50ohm inputs & 14-bit DACs 50ohm outputs. The board has a 3x bigger dual-core Arm Cortex A9 + Xilinx Zynq 7020 FPGA, ultra low phase noise 122.88MHz clock and 1Gbit ethernet connectivity.

RF inputs are improved in terms of distortions, noise & crosstalk which significantly improves receive and use of antenna diversity. A bigger FPGA provides more real-time processing capabilities. The clock was changed from 125MHz to 122.88MHz so it’s more hardware compatible with HPSDR. The new device has not changed form factor, so it directly replaces the current STEMlab platform. The improved performances of the STEMlab 122.88-16 SDR make it easy to build SDR transceivers & other scientific devices to compete with high-end products.
