Transmitter and method for simultaneously transmitting plural signals

摘要

The present invention relates to a transmitter for simultaneously transmitting plural signals. The transmitter comprises at least two converters 10a and 10b. Each converter 10a and 10b is adapted to convert an input signal into an analogue output signal. Each of said analogue output signals has a particular carrier frequency A combiner 40 combines the analogue signals from the converters 10a and 10b. The combiner 40 receives the analogue signals and outputs a single combined analogue signal. An amplifier (20) receives the combined analogue signal and outputs an amplified analogue signal to an antenna.
