Patent ID: 8521198

Claim:
An apparatus comprising at least one processor configured to: determine channel conditions observed by a receiver; select a set of switch points from multiple sets of switch points including a first set of switch points to be used in the presence of jammers having a first amplitude, a second set of switch points to be used in the presence of jammers having a second amplitude and a third set of switch points to be used in the absence of jammers; select from the set of switch points for multiple gain states of a variable gain amplifier of the receiver based on the channel conditions, wherein at least one set of switch points is for decreasing a gain of the amplifier in the presence and upon detection of jammers; select a bias current to be conveyed to the amplifier based on the channel conditions, the processor further configured to select a first bias current upon detection of jammers and a second, lower bias current in the absence of jammers; and select the multiple gain states in accordance with the switch points.
