    Abstract: A supply voltage to a power amplifier is controlled. A signal at a single point in a power amplifier is detected (600). A signal parameter is determined (602) for the detected signal. The signal parameter is compared (604) to at least one predetermined limit. This comparison result is used to determine (606) whether to adjust (608) a supply voltage to the power amplifier. The signal parameter is, for example, an average power or a peak-to-average power ratio.

    Abstract: A circuit and method for protecting a radio frequency power amplifier against peak drain voltage. A detector circuit (200) has an input connected to a drain of a power transistor of an amplification stage of the power amplifier to detect a peak drain voltage therefrom. The detector circuit outputs a protection signal when the detected peak drain voltage exceeds a predetermined reference level. A shutdown circuit (202) is coupled to the detector circuit and inputs the protection signal therefrom. The protection signal is used to remove a gate bias of at least one amplification stage of the power amplifier. High frequency components are used in the detector and protection circuits to immediately reduce the drain voltage from one or more of the amplification stages.

    Abstract: If the mobile station (101) locates a peer it will request network metadata and may obtain location related services or service lists. The mobile station (101) negotiates with one of more peers (103) to share the work load of background scanning for network services. After successful negotiation, any peers in the "discovery net" will report or advertise to each other of any newly discovered networks, or networks to which connectivity has been lost. Since the various mobile stations may, when powered on, scan periodically for network changes, the metadata stored on the mobile station (101) will be dynamic and will change periodically upon travels and/or encounters with additional peers. Because the peers (103) may also possess location information, the mobile station (101) may additionally adjust its scan to prioritize services advertised by those members of peers (103) that are located most proximate to the mobile station (101).
