Patent attributes
A receiving system includes a controller that selectively activates one or more of a plurality of paths between an input of a first multiplexer and an output of a second multiplexer. The receiving system includes a plurality of bandpass filters, each one of the bandpass filters being disposed along a corresponding one of the plurality of paths and configured to filter a signal received at the bandpass filter to a respective frequency band. The receiving system also includes a plurality of variable-gain amplifiers (VGAs), each one of the plurality of VGAs disposed along a corresponding one of the plurality of paths and configured to amplify a signal received at the VGA with a gain controlled by an amplifier control signal received from the controller. At least one, but not all, of the VGAs is a fixed-gain amplifier with a bypass switch to selectively bypass the fixed-gain amplifier.
