Abstract
A method and system are provided for converting wideband analog radio frequency (RF) signals to a digital domain. In an implementation, the system comprises: an amplifier for receiving and amplifying a first wideband analog RF signal comprising one or more first narrowband analog RF signals, each first narrowband analog RF signal occupying a distinct non-overlapping spectral band within a spectrum of the first wideband analog RF signal; N down converter modules; N analog-to-digital converters (ADCs); and a cross-connect for connecting any one of the N down converter modules to one or more of the N ADCs to analog-to-digital convert only the first narrowband analog RF signals occupying the distinct non-overlapping spectral bands. The method and system of the present disclosure track the occupied bandwidth of the narrowband analog RF signals that make up a wideband analog RF signal rather than a total bandwidth of the wideband analog RF signal.
