Patent ID: 8217833

Claim:
An integrated circuit (IC) for simultaneously down converting global navigation satellite system (GNSS) signals in first and second signal frequency bands, which circuit comprises: first and second signal paths receiving GNSS signals corresponding to the first and second signal frequency bands respectively; a common local oscillator/synthesizer (LO/Synth) connected to and driving each of said signal paths; the LO/Synth including a common programmable divider providing a sample clock signal to each of said signal paths and adapted for simultaneously down converting said signals to a lower intermediate frequency (IF); first and second analog-to-digital converters (ADCs) each connected to said common programmable divider, each said ADC receiving a down-converted signal as an input and providing a digital signal as an output; each said signal path being adapted for connection to and receiving input from a multiplexer with multiple outputs and located externally to said IC; first and second low-noise amplifiers (LNAs) in said first and second signal paths respectively and each electrically connected to a respective multiplexer output; and said first and second signal paths being adapted for connection to first and second band pass filters (BPFs) with said first and second BPFs being located externally to said IC and adapted for connection to said first and second LNAs respectively.
