    摘要: A radio transceiver (400, 450) is intended for transmission and reception of radio signals in two frequency bands, and it comprises a first signal input (101) for receiving radio signals in the first frequency band, and a second signal input (102) for receiving radio signals in the second frequency band. In addition, it comprises a first mixer connected to the first signal input (101) for mixing the radio signals (DCS RX) in the first frequency band onto a predetermined first intermediate frequency (IF1); a second mixer (404) for mixing the first intermediate frequency (IF1) onto a predetermined second intermediate frequency (IF2); and a third mixer (402, 461) connected to the second signal input (102) for mixing the radio signals (GSM RX) in the second frequency band onto a predetermined frequency (IF2), which is substantially the same as the second intermediate frequency.

    摘要: A communication device (1) comprising a first part (2); a second part (3); coupling means (4) for coupling the first (2) and the second part (3) and allowing a mutual movement about a hinged joint (AA); and a connection point (5) for an insertable plug. Said point of connection (5) is arranged to said coupling means (4) and it substantially coincides with the hinged joint (AA) of the device (1). Consequently, the external connection will not interfere with the pivoting movement nor will it complicate handling and holding of the device.

    摘要: A transceiver is described which in a FDD mode of operation receives at a first frequency (F1) and transmits at a second frequency (F2); and in a TDD mode of operation receives and transmits at a third frequency (F3). The transceiver incorporates in a receiving branch at least a first mixer for forming a first intermediate frequency (IF1) from a received frequency (F1, F3) and a first local oscillator frequency (LO1); and a second mixer for forming a second intermediate frequency (IF2) from the first intermediate frequency (IF1) and the second local oscillator frequency (LO2). In a transmission branch the transceiver includes a modulator for modulating signals to be transmitted (TXI, TXQ) to a third intermediate frequency (IF3); a third mixer (16) for forming a transmission frequency (F2, F3) from a third intermediate frequency (IF3) and a fourth local oscillator frequency (LO4). Also included is a first synthesizer for forming equally high first and fourth local oscillator frequencies (LO1, LO4), and a second synthesizer and a frequency multiplier or divider and a switching arrangement for forming and switching a fourth frequency (FS) and its M times multiple (M*FS) such that the fourth frequency (FS) is an absolute value of the difference between the reception frequency (F1) and the transmission frequency (F2) of the FDD mode of operation divided by (M-1).
