Abstract:
A device for converting RF pulses received by a wideband impulse radio receiver into one or more baseband signals, the device comprising:a. an RF input for receiving the RF pulses; b. multiple timing inputs for receiving separate timing signals; c. multiple converter circuits, the converter circuits each having a signal input electrically coupled in parallel to the RF input; d. each converter circuit having a second input electrically coupled to one of the timing inputs such that each converter circuit can receive one of the separate timing signals; e. each converter circuit having a baseband signal output; f. the device is packaged as a single integrated circuit in which the converter circuits are arranged on a common substrate for single or concurrent operation; g. wherein each converter circuit includes a signal integrator that is responsive to one of the separate timing signals and that integrates the RF pulses to provide a converter output signal coupled to a corresponding one of the baseband signal outputs; and h. wherein each signal integrator comprises a capacitor having first and second capacitor terminals electrically connected to the signal input, and wherein the RF pulses are provided to the signal integrator as a differential signal applied across the first and second capacitor terminals.
