Thank You, Stretch Goals, and a Network Launch

First of all, a big thank you all for supporting XTRX campaign and congratulations to everyone interested in SDR! The $108k/120% funding raised for XTRX so far is the best evidence that it’s time for off-the-shelf, embedded SDR solutions.

When we launched the campaign we had some stretch goals in mind and one of them ($100,000) has just been hit, so we’ll add a more precise temperature monitoring chip for better calibration.

If we hit $160,000 before the end of the campaign, it will allow us to upgrade the TCXO DAC to 16-bit resolution. With a 16-bit TCXO DAC and GPSDO, we can go below 1 ppb reference clock stability. A great feature if, for example, you’re building a distributed antenna array, and something you’ve never seen with low-cost SDRs.

In the meantime, next week not only marks the end date of the XTRX campaign, but also a commercial launch of the first network where Fairwaves has supplied everything from BTS to a core network, billing system, seamless integration with Wi-Fi, and interconnect with the global SS7 network. This news is relevant to XTRX because the UmSITE BTS in that network is built with Fairwaves SDR technology. Unlike many SDR companies, we design SDRs because we use them in our own products, and we make robust and high-performance SDRs because this is what we need ourselves. At the same time, unlike telecom companies who design good SDRs, we make those SDRs available to everyone to foster innovation and lower the barrier to entry.

Product Choices



Get an XTRX revision 4 board. Does not include any cables, antennas, or adapter boards.


XTRX Deluxe Bundle

Get an XTRX revision 4 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 PCIe Octopack

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


XTRX Beta Tester

Here's your chance to get an XTRX board as soon as possible. We'll send you an XTRX revision 3 board as soon as the campaign reaches its funding goal and we'll follow up with a production version (revision 4) as soon as they come off the assembly line.
