Appliance for receiving radio frequency signals, usable in particular for the management of uplink signals

A receiver device for receiving radio frequency signals, comprising:

• an input port of a radio frequency input signal;
• a first amplification unit connected to said input port;
• a second amplification unit connected to said input port;
• an output port connected to said first amplification unit and said second amplification unit;
• a first bypass connected to said first amplification unit;
• a second bypass connected to said second amplification unit;
• and
• an adjustable notch filter operatively connected to said first amplification unit and said second amplification unit and adjustable depending on an interference frequency of a disturbance signal of said input signal, said adjustable notch filter configured to receive said interference frequency without said input signal having previously passed through said adjustable notch filter,
• wherein said adjustable notch filter is arranged upstream of said second amplification unit so as to be configured to eliminate strong interference in said radio frequency input signal,
• wherein said adjustable notch filter is arranged downstream of said first amplification unit so as to be configured to limit a noise figure of said radio frequency input signal, and
• wherein said first bypass and said second bypass are operable to alternatively select said first amplification unit or said second amplification unit.
