Receiver with auto gain control circuit of RF signal

A receiver comprising:

• an attenuator for attenuating an antenna input signal;
• a first filter for receiving an output signal from the attenuator;
• an RF amplifier for amplifying an output signal from the first filter;
• a second filter for receiving an output signal from the RF amplifier;
• and
• a control circuit for controlling an attenuation of the attenuator based on the output signal of the first filter and the output signal from the second filter and controlling a gain of the RF amplifier based on the output signal from the second filter, but not based on the output signal from the first filter.

A receiver comprising:

• an attenuator for attenuating an antenna input signal and producing an output signal;
• a first filter for filtering the output signal of the attenuator and producing an output signal;
• an RF amplifier for amplifying the output signal from the first filter and producing an output signal;
• a second filter for filtering the output signal from the RF amplifier and producing an output signal;
• a first auto gain control circuit including a first auto gain control driving stage outputting a first control signal for controlling the gain of the attenuator;
• and
• a second auto gain control circuit including a second auto gain control driving stage outputting a second control signal for controlling the gain of the RF amplifier and for controlling the gain of the attenuator, wherein an input signal for the second auto gain control driving stage has a smaller bandwidth than that of one for the first auto gain control driving stage.
