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



Get an XTRX Pro board. Does not include any cables, antennas, or adapter boards.


XTRX Pro Deluxe Bundle

Get an XTRX Pro board as well as an Antennas + Cables set, a PCIe x2 + Front End Adapter, and a USB 3 Adapter with Aluminum Enclosure (see below for details). Also comes with four extra U.FL-to-U.FL cables and four extra U.FL-to-SMA-male cables.


Antennas + Cables

A full complement of cables and antennas for your XTRX, including four RF antennas (95 mm, 2 dBi, SMA male, GSM/3G/LTE 880 - 960 MHz, 1710 - 1990 MHz), one GPS antenna, and five cables.


USB 3 Adapter with Aluminum Enclosure

This adapter converts your XTRX from Mini PCIe to USB 3 and comes with an aluminum enclosure designed specifically for XTRX. The adapter has three status LEDs, a micro USB 3 port, one SMA connector for the GPS antenna, four SMA connectors for the MIMO Tx/Rx antenna pairs, a micro SIM card slot, and a slot for a GPIO FPC cable. Comes with a USB cable and all RF cables for internally connecting an XTRX to the SMA connectors. Does not include an XTRX, antennas, or FPC cable.


PCIe x2 + Front End Adapter

This PCIe card securely holds an XTRX board (not included) so it can be used in a standard PCIe x4 slot. It includes an RF front end with a LNA and PA for up to 100 mW output on each channel. A TDD switch is incorporated for applications like TDD LTE. You can bypass the front end by attaching cables directly to XTRX. 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. A micro SIM card slot is also present.


XTRX Pro PCIe Octopack

This single PCIe card comes loaded with eight (8!) removable XTRX Pro boards, metal installation brackets, enough cables for all GPS and MIMO Tx/Rx ports, and a special board for synchronizing all eight XTRX Pro boards.
