Publication number: 20110096766Abstract: A transceiver circuit and a method in a wireless communication network are provided, where a signal power level for a signal received at the transceiver circuit is measured and compared to a predefined threshold power level. At least two groups of power amplifiers may be used, where one group is optimized for high efficiency above the predefined threshold power level, and one group is optimized for high efficiency below the predefined threshold power level. The amplifiers may be used to amplify the received signal depending on the signal power level in relation to the predefined power threshold level. The signal may then be filtered by duplex filters and forwarded to a diversity antenna or a main antenna where it is transmitted over an air interface.Type: ApplicationFiled: December 9, 2010Publication date: April 28, 2011Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventors: Bogdan TUDOSOIU, Phillip Marc Johnson, William O.

Publication number: 20070161357Abstract: The invention relates to a multiband antenna switch, and more particularly an antenna switch implemented in the radio interface of a mobile telephone device. The antenna switch comprises a power amplifier module with an antenna port 1 connectable to an antenna, and at least one input port connectable to a transmitter section of a transceiver 5; a front end module connectable to the antenna port and a reception section of a transceiver; wherein said power amplifier module and said front end module are capable of covering a number of frequency bands. The transmission/reception duplexing function is obtained by means of a circulator 6, 7 or a power splitter arrangement. The antenna switch offers a packed solution for using four GSM and eight WCDMA bands in the same phone.Type: ApplicationFiled: September 18, 2006Publication date: July 12, 2007Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventors: Bogdan Tudosoiu, William O Camp
