  • an antenna responsive to received signals;

    an input amplifier responsive to the received signals from the antenna, said input amplifier amplifying the received signals;

    a frequency down-converter responsive to the amplified received signals from the input amplifier, said frequency down-converter down-converting the frequency of the amplified received signals to an intermediate frequency (IF) signal, said frequency down-converter passing the IF signal over a predetermined frequency band capable of including multiple received signals, said frequency down-converter simultaneously down-converting the multiple signals;

    an analog-to-digital converter responsive to the IF signal from the frequency down-converter, said analog-to-digital converter converting the IF signal to a digital signal; and

    a digital channelizer responsive to the digital signal from the analog-to-digital converter, said digital channelizer separating the digital signal into a plurality of separate received signals simultaneously down-converted by the frequency down-converter.
