Patent number: 8224260Abstract: A radio frequency (RF) signal transmission/reception apparatus and an RF signal transmission/reception method are disclosed. The RF signal transmission/reception apparatus is adapted to perform a transmission/reception duplex function using a bi-directional mixer at the IF band or baseband, not at the RF band. When a reception signal of the RF band is passed through the bi-directional mixer, it is converted into a signal in any one of the IF band and the baseband. Also, when a transmission signal in any one of the IF band and the baseband is passed through the bi-directional mixer, it is converted into a signal of the RF band.Type: GrantFiled: December 8, 2006Date of Patent: July 17, 2012Assignee: LG Electronics Inc.Inventors: Hong Teuk Kim, Kwy Ro Lee, Sergey Sergeyev, Sergey Khvorov, Alexander Belonozhkin
