Abstract: Disclosed aspects relate to methods and apparatus for controlling a wireless device having at least one radio frequency (RF) system. The methods and apparatus are configured to select an antenna for transmission of signals from radio components of the at least one RF system from between a first default antenna normally coupled to the radio components of the at least one RF system for transmission of signals and one of a plurality of other antennas in the wireless device. Further, switching is configured to couple the radio components to one of the other plurality of antennas selected as the antenna for transmission cycles when the radio components are transmitting in an antenna switch diversity (ASDIV) period. Additionally, the methods and apparatus are configured to operate a switch to couple the radio components back to at least the first default antenna during receiving cycles during the ASDIV period.

Abstract: Disclosed aspects relate to methods and apparatus for coexistent radio frequency (RF) systems in a wireless device. Control of a wireless device includes detecting when a turn on signal is issued to a first radio system, and then controlling the second radio system to either modify the operation of receiver circuitry in the second radio system to protect components within that system, or modify transmit circuitry to stop transmissions for protecting components within one radio system potentially affected by transmission from the other radio system in the wireless device. Disclosed also is monitoring of transmission states of the radio systems based on reading messages between the first and second radio systems and issuing a notification message based thereon such that one of the radio systems may suspend monitoring of a transmit channel for permission to transmit in order to reduce power consumption due to such monitoring of the channel.

Abstract: An apparatus and method for filtering a signal in a phase lock loop is disclosed. An typical apparatus for filtering a phase error signal comprises a first filter subcircuit receiving a phase error signal from a phase comparator and filtering the error signal when enabled, a second filter subcircuit receiving the phase error signal from the phase comparator and filtering the error signal when enabled and first and second enable switches which are activated in combination to control filtering of the error signal. The first filter subcircuit is enabled by activating a first combination of the enable switches and the second filter subcircuit is enabled by activating a second combination of the enable switches. A fast acquisition subcircuit can also be used to temporarily underdampen the filter and improve overall performance of the phase lock loop circuit. The filter can be used to obtain multimode operation in a cellular radio.

Abstract: A novel and improved dual band antenna system (100) comprising an inner antenna element (102) surrounded by an outer antenna element (104). In a first embodiment, the inner antenna element (102) radiates and receives RF signals in a first RF band, and the outer antenna element (104) radiates and receives RF signals in a second RF band. Optionally, the inner and outer antennas may be coupled together when operating in the first RF band in order to improve the antenna gain pattern of the dual band antenna (100). In a second embodiment, the inner antenna element (102) radiates and receives RF signals in both the first and second RF bands. In this second embodiment, when operating in the second RF band, the outer antenna element (104) is a grounded, thus altering the signal length of the inner antenna element (102) to resonate in the second RF band.
