Abstract
Techniques for a communication device with a receiver to dynamically control the gain of an analog front end of the receiver. Rather than having a single circuit path in the analog front end, the analog front end includes multiple circuit paths, and dynamically selects one of the circuit paths that optimizes the gain of the analog front end. For example, an amplifier circuit path may be selected to amplify the power level of the signal received from the antenna. However, the analog front end may further include an attenuator circuit path that includes an attenuator to reduce the power level of a high-power input signal received from the antenna to ensure that the high-power signal is attenuated below a power level associated with saturation of the receiver.
