Abstract
A rejection converter is disclosed for use in a transmitter for operating in at least either of a first mode for transmitting signals within a first frequency range, and a second mode for transmitting signals within a second frequency range. The rejection converter includes an input unit for receiving an input signal in at least either of the first or second frequency ranges. The rejection converter also includes a rejection unit for rejecting at least one spurious harmonic signal associated with the first frequency range that falls within the second frequency range. The rejection converter permits signals in the second frequency range to be passed when the output signal is within the second frequency range.
