  • Radio frequency signal attenuation circuitry and gain controlling unit
    Patent number: 6993303
    Abstract: The present invention avoids distortion in a radio frequency device due to a received RF signal which has a voltage strength that is too high. The invention comprises a radio frequency signal attenutation circuitry, a radio frequency signal processing circuitry, intermediate frequency processing circuitry, and a gain controlling unit. The gain controlling unit is configured to output a control signal to the radio frequency signal attenuation circuitry and intermediate frequency processing circuitry. The radio frequency signal attenuation circuitry is configured to attenuate a radio frequency signal prior to being processed by radio frequency processing circuitry and intermediate frequency processing circuitry. Accordingly, saturation in the radio frequency signal processing circuitry and intermediate frequency processing circuitry is avoided.
