XTRX Campaign is Live!

Thank you for signing up for updates on the XTRX software-defined radio project. The XTRX campaign is going live today; please follow along, pledge, and help spread the word about this project!

We’ve been dreaming about a world where software-defined radio is widespread and easily embeddable since we first learned about SDR in 2008. I still have draft diagrams and sketches of schematics of a Mini PCI SDR we tried to build in 2009 as a generic SDR platform — there was no Mini PCIe, only Mini PCI back then. Neither the market nor the technology was ready, the project didn’t fly, and we spent the next several years building specialized SDRs for cellular communications. Now, almost ten years later, we want to give our dream another shot with XTRX SDR. We feel it’s time.

Some of you may remember our XTRX presentations at OsmoDevCon‘16, GRCon‘16, 33C3, OsmoDevCon‘17, OpenCellular Workhop‘17, or GRCon‘17, and how every time we promised that XTRX would be ready "soon." The "soon" is finally here, today.

We’ve tried to answer most common questions on the main campaign page but we surely missed some. Don’t hesitate to reach out if you have a question.

Stay tuned, get an XTRX.

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.



We are a vertically integrated vendor of cellular equipment focused on the needs of emerging markets.
