摘要： A current source circuit includes a first transistor Q1, a second transistor Q2, a first resistor R1, and a second resistor R2. The first transistor Q1 has a first terminal (collector) coupled with the supply voltage (VCC), a second terminal (base) coupled with the first resistor R1, and a third terminal (emitter) coupled with the second resistor R2. The second transistor Q2 has a first terminal coupled with the second terminal of the first transistor Q1, a second terminal coupled with the third terminal of the first transistor Q1, and a third terminal coupled with the filtering circuit 39. The first resistor R1 is coupled between the supply voltage and a second terminal of the first transistor Q1. The second resistor R2 is coupled between a third terminal of the first transistor Q1 and the filtering circuit 39.

摘要： A radio frequency signal amplifying system includes an amplifier having an input terminal and an output terminal, an attenuator electrically connected to the input terminal of the amplifier, a peak power detecting module configured to apply a peak power attenuation signal to the attenuator by taking a peak power level of an input signal into consideration, and an average power detecting module configured to apply an average power attenuation signal to the attenuator by taking an average power level of an output signal from the output terminal into consideration. The attenuator is configured to generate the attenuated signal to the input terminal of the amplifier by taking the peak power attenuation signal, the average power attenuation signal, or the combination thereof into consideration.
