Apollo MxFE™: Direct RF Sampling at 40GSPS
2024-06-18
With the ever-increasing need for wideband scanning for Comms and EW, the Apollo MxFE™ positions itself as an excellent choice for these applications given the plethora of on-chip DSP functionality. Learn how on-chip FIR filters are leveraged to cancel image power across the Nyquist boundary. A 20GHz quadrature input into adjacent ADCs swept across the desired band of interest gives Apollo MxFE the phase and magnitude information it needs to reject images up to 4GHz iBW from 2-18GHz, effectively doubling the sample rate to 40GSPS. This allows for direct sampling from 2-18GHz, all in one Nyquist.
