Agile Solutions is pleased to announce a new Wideband RF Transceiver
board U-RFX capable of tuning frequencies from 1MHz to 4.4GHz.

The
wide frequency coverage addresses the need for single RF transceiver
board capable of meeting various application needs ranging from 1MHz to
4.4GHz with 50 MHz of RF Bandwidth.

Agile Solutions is Startup Company
Started in 2010 with goal to produce low cost software Defined Radio
Solutions for Teaching, Research and Prototype Solutions.

Our first
Universal RF Transceiver board U-RFX is developed to address GNURADIO
and USRP.

U-RFX board seamlessly works with USRP family of
boards.

U-RFX is Full duplex RF Tranceiver board and operates in two
modes

Low Frequency Operation: 1MHz to 200MHz, same as Basic TX and
Basic RX
High Frequency Operation: 200MHz to 4.4GHz
MAX RF Output
Power: 17dBm with upto 25dB Output power control
MAX RF Input Power:
-15dBm with upto 45dB gain control
Receiver Sensitivity: -115dBm upto
3.8GHz and -95dBm upto 4.4GHz
Receiver Noise figure: 6-8 dB

U-RFX is
MIMO capable:All the LO’s on U-RFX board are phase synchronous with
respect to motherboard clock. By using two or more U-RFX boards, NxM
MIMO can be realized.

U-RFX board is available for purchase at an
introductory price of 700 USD.

Universal RF Tranceiver board U-RFX is
designed with Zero IF direct conversion architecture and has onboard
Local Oscillators, Mixers, Switches, LNA’s and Power amplifiers.

Hi,

I am testing 4 new USRP N210 out-of-the-box. Both direct cable
connection and connection through 1 Gbit switch has been tested. Same
result: ping times out, but Wireshark reveals ping reply from USRP N210
at network interface card level. Wireshark data also reveals checksum
error in ICMP (reply from box). Needless to say, that command
“uhd_find_devices” comes out with “No UHD Devices Found”. Ping tests
have been done both in Windows (from command prompt) and from Ubuntu
platform.

Tests have been carried out with two labtops - both equipped with 1Gbit
network cards (validated). Ping between the two labtops configured as
192.168.10.1 and 192.168.10.3, respectively, checks out ok.

Any good ideas out there ?? I am getting a little frustrated :slight_smile:

Regards,

John

Sounds very interesting.

What is the phase-noise spec ?
How do you define receiver sensitivity? . It’s strange that receiver
sensitivity varies 20dB and noise figure 2dB.
What is your compatibility with UHD?

That’s odd. Can you send me a Wireshark log demonstrating the problem?

Hi Darol,

Welcome to Agile Solutions.

Yes, you are correct. We have not used any RF preselectors.

We will create a place holder for RF filter before the LNA so that
desired filter can be installed(if required) for the target application.

Please check this link for off the shelf available filters

We would like to use this U-RFX board in one of our projects at the
university in Russia. Paid for the purchase in November 2011 and is
still in April 2012 have not received anything.
Agile Solutions on our letters do not respond.
What to do?

Such a broad-band Rx front-end, depending on the environment, can
require more dynamic range than you’ll have downstream. Do you have RF
preselectors before the amplification and mixing stages? Many
broad-band, high-performance RF receivers will have a switchable
filter bank (usually containing a bank of SAW or BAW filters) to
divide the antenna RF into bands of a few hundred MHz. After looking
at your website and considering the price that you have listed, I
doubt that you’re doing this.

I’ve been considering building a USRP compatible receiver board with
preselectors, but would like to find one off-the shelf.
