Abstract
Abstract Methods, systems and computer program products are provide which control the operation of a receiver of a wireless device so as to reduce the power consumption of the receiver by setting the third order intercept point of a low noise amplifier based upon at least one of a strength of a signal received by the wireless device or a transmission power of a transmitter of the wireless device. Furthermore, the gain of the low noise amplifier may also be set based upon received signal strength or transmitter power. Also, the gain of an amplifier associated with a mixer of the receiver may be set based upon received signal strength or transmitter power. Preferably, multiple power modes are provided to tailor the power consumption to the operating conditions of the wireless device.
