  • Controllable attenuator
    Patent number: 6683511
    Abstract: A controllable attenuator has an input and an output, and comprises a first resistive element, a first capacitor connected in series between the input and the output, a first controllable shunting transistor connected between the output and a supply terminal via a second resistive element, and a controllable bypass transistor connected between the input and the output. The controllable attenuator may form part of a radio receiver circuit, the attenuator being positioned between a matching circuit and a low-noise amplifier.
    Type: Grant
