| Abstract(in English) | We have investigated on a multimode/multiband receiver with an RF receiver chain. Basically, an RF band pass filter at the RF front end prevents multimode/band communications because of little flexibility of the BPF. Therefore, we have tried to design multimode/multiband receivers with an ultra wide band RF BPF. While pass-band of the RF-BPF is widened, an IF-BPF with relatively narrow pass-band is applied in the receiver, which is so called "heterodyne receiver". As is known, however, the heterodyne receiver with the ultra wide band RF BPF suffers from severe image-band interference. Therefore, we have proposed dual frequency conversion heterodyne receiver with some image-band interference cancellers to overcome the problem. In this report, principle of image-band interference cancellation is briefly explained and challenges for implementing the imageband interference cancellers are described. |
