Pl advice.
Thanks,
Sudhir.
The schematics are available, the PCB files and gerbers are not.

WindyCitySDR received a Patent on March 20, 2013 for this since the PCB
layout was drawn from SCRATCH, and will be manufacturing these devices
out
of Chicago, Illinois USA!
WindyCitySDR received this device in October of 2012. November 2012,
swapped the 64Mhz Clock for a 52Mhz Clock and have been demonstrating it
around Chicago. WindyCitySDR is working with Akash Kosgi of Bangalore,
India.
This device is a:
**
**
2x2 full duplex MIMO SDR System housing complete RF and DAQ subsystems
on a
single board. Its architecture is designed for a true MIMO System. It
meets
the unique architecture required for MIMO systems which are not part of
traditional MIMO hardwares using common clock for RF subsystems where a
continuous RF phase tracking is required. Coupled with these benefits it
hosts onboard RF Transceiver subsystems capable of tuning frequencies
from
400MHz to 4.4GHz.
All Ettus R. USRP1 Applications works with this daughtercardless
SDR
device!
Hardware Components:
Altera Cyclone FPGA 12K

Dual 400MHz to 4.4GHz Quadrature Modulators with fine tuning resolution
of
1Hz
Dual 400MHz to 4.4GHz Quadrature De-Modulators with fine tuning
resolution
of 1Hz
LNAs, Power amplifiers and attenuaors

MAX RF Output Power: 17dBm with upto 25dB Output power control
Receiver Sensitivity: -115dBm upto 3.8GHz and -95dBm upto 4.4GHz
Receiver Noise figure: 6-8 dB
AndroidSDRv1001 is a LiveDVD/USB image to support this SDR device
without
the Configuration Nightmares, and when connected to appropriate SDR
hardware allows for creating “Software Defined Radio GSM Mobile Phone
Networks”, for example.
This includes Android Studio 0.1.1 Build 130.687321 Environment, as well
as
contains:
*Asterisk 1.8 *
GCC 4.6.3
*GNU Radio 3.4.2 + GRC *
*Java 1.7.0_21 *
*OpenBTS 2.8 *
Ubuntu 12.04 LTS 32-bit
Pre-Configured to work with Google Voice, Just add your Google Voice
Email
Address & Password.
You should be able to boot off the LiveDVD / USB image, and create a SDR
GSM Network in under 10 minutes cleanly.
UHD Driver to be implemented next, along with Fairwaves UmTRX UHD
Driver, & PerVices Nectar PCIx Driver.
If you are within the USA , Part 15 of the FCC Rules & Regs allows for
utilizing SDR devices as Test Equipment.
Ettus R., PerVices, & other Software Defined Radio providers sell
their products under the following (Generally Speaking):
Licensing
The USRP is sold as test equipment. If you choose to use your USRP and
daughterboards to transmit using an antenna, it is your responsibility
to
make sure that you are in compliance with all laws for the country,
frequency, and power levels in which the device is used. Additionally,
some
countries regulate reception in certain frequency bands. Again, it is
the
responsibility of the user to maintain compliance with all local laws
and
regulations. Licensing | Ettus Research, a National Instruments Brand | The leader in Software Defined Radio (SDR)
