[ANN] Bitshark USRP RX daughterboard

Continuing down the path blazed by Ettus R. with their RF
daughterboards for the USRP, Epiq Solutions
(http://www.epiq-solutions.com) is pleased to announce the Bitshark
USRP RX (BURX) daughterboard. The BURX daughterboard provides a single
channel RF receiver capable of tuning between 300 MHz and 4 GHz,
supporting RF channel bandwidths up to 50 MHz. It provides the high
performance and flexibility necessary to handle a multitude of present
and future wireless radio standards, including:

-GSM (850/900/1800/1900 MHz)
-iDEN (800 MHz)
-UMTS (Bands I-XIV)
-CDMA2K/EVDO (450/800/1900/2100 MHz)
-TD-SCDMA (1920/2025/2400 MHz)
-WiFi/802.11b/g (2.4 GHz)
-WiMAX/802.16e/d (2.3-2.7 GHz, 3.3-3.8 GHz)
-LTE (Bands 1-40)
-TV Whitespace (400-700 MHz)
…plus many others

The BURX daughterboard provides the gain control and configurable
baseband channel filtering required to optimize receiver sensitivity.
It also includes a temperature-compensated crystal oscillator (TCXO)
that provides a highly-stable low-jitter reference clock. This clock
signal is accessible (via a U.FL connector) for use as the USRP’s
reference clock and/or for multiple-input (i.e. MIMO) configurations
using more than one BURX daughterboard. The USRP reference clock can
also be used as the clock source for the BURX daughterboard if

GNU Radio software support for the BURX daughterboard has been
completed and will be integrated into the GNU Radio git tree under the
GPLv3 license. Epiq Solutions is also currently developing open source
GNU Radio applications that will demonstrate the flexibility and
performance of the BURX daughterboard.

BURX daughterboards will be available in April 2010 for $750 USD
(commercial use) or $550 USD (academic use). Boards are being
reserved for customers on a first come, first served
basis. Please visit:


for details on how to reserve a card and for additional information.

Epiq Solutions’ mission is to provide reconfigurable radio solutions
that open up access to the ever-increasing list of radio standards.
The BURX daughterboard is our first step in this process, and we are
excited to contribute to the hardware and software ecosystem of the
USRP and GNU Radio.
