Abstract
A receiver is provided and includes a first amplifier configured to amplify, based on a first gain, a radio frequency signal to generate a first amplified signal. The radio frequency signal is received by the receiver on a first channel. A second amplifier generates, based on the first amplified signal and a second gain, a second amplified signal. An output circuit generates a baseband signal based on the second amplified signal. A first detection circuit compares the baseband signal to (i) a first threshold in response to the first gain being at a first level, and (ii) a second threshold in response to the first gain being at a second level. The first detection circuit generates a first detection signal in response to the comparison. A controller, in response to the first detection signal, (i) adjusts the second gain, or (ii) changes the receiver from the first channel.
