Regarding Transceiver design on GNUradio

Dear all,
I am working on re-configurable Software defined radio based
multiband
transceiver (initially for ISM band 2.4 GHz).for that i am using GNU
Radio
for software design .For hardware design i come to know that Development
Boards (i)USRP Motherboard (ii)RFX2400 or SBX40 or CBX40 are required .
my quires are
(1) Is GNU radio software is sufficient for full transceiver design ?
(2) What other components are required in the hardware circuits?
(3) What is the cost of USRP motherboard, RFX2400,SBX40 and CBX40 ?

Thanks in advance
amit

(1) Is GNU radio software is sufficient for full transceiver design ?

Have a read of this page for more information on what you can do with
GNU
Radio:

(2) What other components are required in the hardware circuits?

You’ll need an antenna resonant for the target frequency ideally with an
SMA Male connecter.

(3) What is the cost of USRP motherboard, RFX2400,SBX40 and CBX40 ?

Ettus motherboards, specifications and prices can be found here:

See the Ettus product page for their daughterboards, prices,
simplex/duplex
capabilities and frequency ranges:

Be aware that the WBX only goes up to 2.2GHz so does not cover the
wanted
2.4GHz ISM band.

Ettus isn’t the only manufacturer of GNU Radio compatible hardware so
have
a look here for other options:
