  • METHOD AND APPARATUS FOR REDUCING PEAK CURRENT VARIATION IN A RADIO
    Publication number: 20100022209
    Abstract: The application discloses a method and apparatus for reducing peak current variation in a radio. The method includes monitoring (202) output power of a power amplifier (106) and determining (204) that the output power of the power amplifier is above a predefined threshold. The method then includes controlling (206) input power of the power amplifier (106) so that the output power is reduced below the predefined threshold. The method further includes isolating the power amplifier (106) from receiving signals reflected from an antenna (112) such that the output power is maintained below the predefined threshold. The method then includes effecting (208) amplification of a radio frequency signal at the maintained output power in the linear region of operation such that the radio frequency signal is amplified with reduced peak current variation.
