Hi,
i am trying to use 3gsps adc of e2v's ev10as152a, the datasheet is claiming that this adc can give upto 5GHz bandwidth (better SFDR even in 2nd and 3rd Nyquist zones). but when i calculate FFT for this digital data(after down sampling) i can only get Fs/2 bandwidth i.e i can only get upto 1.5Ghz frequency calculation. How can i calculate frequency in 2nd and 3rd Nyquist zones using FFT(without using any analog filters before ADC). I am using FFT core of Xilinx in Virtex-6 Fpga.
Thanks in Advance,
Naidu.
