Multiband receiver for satellite navigation

摘要

The receiver has a high frequency receiving chain including a receiving unit with an amplification stage having a low noise amplifier (31) that delivers signal filtered from received radiocommunication signal. The receiving unit has a received frequency processing stage provided with a switch (S1) that delivers the filtered signal alternatively in two paths, based on received frequency. The processing stage has an adjustable amplifier (A6) that amplifies the filtered signal. The processing stage has another switch (S2) that delivers the filtered signal towards a mixer (34).
