Re: [Discuss-gnuradio] Building an RF Front end for DSP FPGA Kits with ADCs

[jan acosta]

I have one already, but you can't receive anything above - 10 dBm.  Plus I'd like to gain FPGA programming experience.

Why not just buy a USRP + WBX?

Hello,

I am looking to buy an Altera DSP FPGA Kit (DSP Development Kit, Stratix III
Edition) for school research but I'm not sure how i am going to build an
RF-Front End for it.  I am looking to receive signals up to +30 dBm from 30

MHz - 2 GHz with bandwidths up to 50 MHz.  This the kit I am looking to
purchase: http://www.altera.com/products/devkits/altera/kit-st3-dsp.html

This kit comes with two 150 MSPS 14-bit ADCs and 250 MSPS 14-bit DACs.  My
question is it possible to buy a Commercial off the Shelf Front-End that
provides the necessary inputs?

Is there something special that I have to do in order to receive signal
levels up to +30 dBm so that my ADCs do not saturate?

My goal would be to build it myself, but if I am pressed with deadlines I
will have to get COTS product.
