发明名称 Multiple transmission apparatus with reduced coupling
摘要 The present invention relates to a transmission apparatus having at least two transmission branches for transmitting respective transmission signals at substantially same frequencies, and to a method of controlling such a transmission apparatus. A first oscillator circuit (62) is provided for generating a first signal at a first frequency to be used in a first transmission branch. Additionally, a second oscillator circuit (64) is provided for generating a second signal at a second frequency to be used in a second transmission branch, the second frequency being different from the first frequency. To enable transmission of the transmission signals at said substantially same frequencies, at least one frequency divider or multiplier (72, 74) is provided for dividing or respectively multiplying at least one of said first and second frequencies by a respective predetermined factor. Thereby, the first and second oscillator circuits can be operated at different frequencies, so that mutual coupling can be reduced.
