Radio transceiver having frequency synthesizer

摘要

A radio transceiver (10) is disclosed. It comprises a first transceiver circuit (15) and a second transceiver circuit (20), the latter requiring an LO signal having higher LO frequency than the former. It further comprises a frequency synthesizer (35) comprising a first clock-signal generator (45) adapted to generate the LO signal for the first transceiver circuit (15) based on a first reference oscillation signal and a second clock-signal generator (65) adapted to generate the LO signal for the second transceiver circuit (20) based on a second reference oscillation signal, which is or is derived from the LO signal for the first transceiver circuit (15). A radio communication apparatus (1) comprising the radio transceiver (10) is also disclosed.
