The first ever truly embedded SDR

Our XYNC Campaign is Live!

by Alexander Chemeris

Last year we launched XTRX, which was very well received by the SDR community. We’d like to start by saying thank you to everyone who helped make it happen. As part of that campaign, we designed, built, and shipped the original Octopack, which immediately became a bestseller. Since then, we’ve been working with Octopack users to refine the product.

Allow us to introduce XYNC – the ultimate low-cost Massive MIMO SDR.

With six different models, anywhere from 8x8 to 32x32 transmit/receive channels, and optional support for 6 GHz RX, XYNC comes in a practical form factor at an affordable price.

Come help us make affordable Massive MIMO a reality!

PS XYNC enjoys special discounted pricing for the duration of the campaign. Retail prices are set to increase after the campaign is finished. If you want to place a volume order, please contact us separately.

Product Choices


XTRX Pro Rev 5

XTRX Pro Rev 5 board. Does not include any cables, antennas, or adapter boards.


PCIe x2 Lite Adapter

This PCIe card securely holds an XTRX board (not included) so it can be used in a standard PCIe x4 slot. This adapter achieves the full 10 Gbit/s raw bus bandwidth and can be plugged into x4/x8/x16 PCIe slots. A six-pin JTAG connector makes it easy to program and debug the FPGA. Includes six SMA-to-U.FL cables, two screws for mounting your an XTRX board, and four 8 cm U.FL-to-U.FL cables.


4G/LTE External Antenna

From the Crowd Supply Basics project.

Abracon External Antennas exhibit low return loss characteristics, high gain, and Low Voltage Standing Ratio (VSWR). These external antennas are linearly polarized and come in a low profile package.


U.FL-to-SMA Cable

From the Crowd Supply Basics project.

A Hirose U.FL to SMA (jack) bulkhead straight connector with a 1.32 mm diameter cable. Less than -2 dB cable insertion loss up to 6 GHz. Both connectors are gold-plated brass and the cable conductor is silver-coated copper.


Active GPS Antenna

From the Crowd Supply Basics project.

A low-noise active GPS antenna suited for the GPS L1 band. Accepts 3-5V DC and outputs RF via an SMA(m) connector. Optional adhesive mounting.
