Patent ID: 7013114

Claim:
A transmitting device, comprising: a transmitted signal generator for generating a transmitted signal; a transmitter amplifier for amplifying and outputting the amplified transmitted signal at an output of the transmitter amplifier, the transmitter amplifier being connected after the transmitted signal generator; a directional coupler for decoupling part of an output power of the transmitted signal generated by the transmitter amplifier and for applying the decoupled part of the output power to the transmitted signal generator to enable control of the output power of one of the transmitter amplifier and a modulation performed by the transmitted signal generator to be achieved, the directional coupler being connected after the transmitter amplifier; and a circuit having a specific impedance which is coupled directly to the output of the transmitter amplifier to match the output of the transmitter amplifier, wherein said circuit does not contain non-reciprocal components, and wherein an impedance of the circuit is chosen so that matching to a wave of an interference signal running in a direction of the output of the transmitter amplifier can be achieved, and a reflection of the interference signal at the output of the transmitter amplifier is accordingly reduced.
