Abstract
An apparatus and method for removing a transmission leakage signal are provided. The apparatus includes: a directional coupler connecting an antenna to a transmission path and a reception path; and a reflection coefficient adjustment unit outputting a reflection signal to the reception path, the reflection signal having the same amplitude as and opposite phase to a first transmission leakage signal generated from the transmission path and input to the reception path and a second transmission leakage signal reflected by the antenna and input to the reception path.
Claims25
A transmission leakage signal removing apparatus comprising:
- a directional coupler which connects an antenna to a transmission path and a reception path;
- and
- a reflection coefficient adjustment unit which outputs a reflection signal to the reception path, the reflection signal having an amplitude which the same as and a phase which is opposite to that of a sum of a first transmission leakage signal generated in the transmission path and input to the reception path and a second transmission leakage signal reflected by the antenna and input to the reception path.
A method of removing a transmission leakage signal, the method comprising:
- (a) receiving a first transmission leakage signal generated in a transmission path of a directional coupler and input to a reception path of the directional coupler, and a second transmission leakage signal reflected by the antenna and input to the reception path;
- and
- (b) outputting a reflection signal to the reception path, the reflection signal having an amplitude which is the same as and a phase which is opposite to that of a sum of the first transmission leakage signal and the second transmission leakage signal.
