The first ever truly embedded SDR

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


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. We are developing, manufacturing, deploying, and operating turn-key cellular network solutions including radio equipment, towers, power and backhaul all the way to a core network and SS7 interconnect. Our team has been building software-defined radios and systems based on them since 2009 and is well known for its ClockTamer, UmTRX, and UmSITE products.
