Abstract
A transmitter for generating modulated signals is shown, wherein in a first-type operating mode, a first digital signal is input into a digital-to-analog converter to obtain a first analog signal that is input into a first-type unit, in which a first-type modulated signal is generated in dependence on at least the first analog signal; and wherein in a second-type operating mode, a second digital signal is input into the digital-to-analog converter to obtain a second analog signal that is input into a second-type unit, in which a second-type modulated signal is generated in dependence on at least the second analog signal. Correspondingly, a wireless communication device is shown, as well as a base station, a module in a wireless communication device, a module in a base station, an integrated circuit, a method, a computer program and a computer program product.
