Abstract: Techniques are provided for a multi-frequency sampling system. A system implementing the techniques according to an embodiment includes a first bandpass filter to filter a radio frequency (RF) signal to generate a first filtered signal in a first frequency band, and a second bandpass filter to filter the RF signal to generate a second filtered signal in a second frequency band. The system also includes a first analog to digital converter (ADC) operating at a first sampling frequency to convert the first filtered signal to a first digital signal and a second ADC operating at a second sampling frequency to convert the second filtered signal to a second digital signal. The first frequency band is selected to avoid a first Nyquist boundary zone associated with the first sampling frequency and the second frequency band is selected to avoid a second Nyquist boundary zone associated with the second sampling frequency.

Abstract: A switch matrix circuit module for routing signals. In an example, the module includes a switch matrix coupled with first and second switches. The switch matrix is configured to receive a plurality of input signals, and output a selected one of the plurality of input signals as a first intermediate signal and another selected one of the plurality of input signals as a second intermediate signal. The first switch receives the first intermediate signal and a first auxiliary signal, and outputs a first output signal, and the second switch receives the second intermediate signal and a second auxiliary signal, and outputs a second output signal. A number of the modules can be coupled together to provide a switch matrix circuit, which can be readily scaled by adding further modules. In an example, the plurality of input signals are radio frequency (RF) signals.
