Thank you to creators Sergey and Andrew who have submitted news about their upcoming software defined radio called 'xMASS SDR'. xMASS will be a SDR with 8 RX and 8 TX channels, with a max sample rate of 60 MSPS per 8 channels, or 100 MSPS per 4 channels, and a frequency range of 30 - 3800 MHz.

The board comes in a modular PCIe form factor, with 4x FPGAs, and GPS/PPS clock sync input. The system is designed in mind for 4G/5G applications but should be useful for other applications too.

xMASS SDR will be crowd-funded on CrowdSupply, and they note that they expect to launch the campaign soon. So if you are interested, sign up for email updates on their CrowdSupply page.

We’re creators (Sergey Kostanbaev and Anrew Avtushenko) of the M.2 uSDR board that we successfully crowdsourced a year ago. Now we want to share our new invention called xMASS SDR, a modular, high-performance MIMO transceiver. It has 8 RX and 8 TX channels that can be synchronized for directional finding, beamforming and more applications. Each SDR module, called xSDR, is based on the LMS7002M chip and can deliver 2 RX and 2 TX channels. Like uSDR, xSDR shares the same form factor and M.2 pinout and both use the same open-source software and gateware stack.

xMASS SDR is ideal for 4G/5G but can be interesting among academic, industrial and advanced hobbyists.
