摘要： There is provided a solution for simultaneous reception of dual channel transmission. The solution is based on applying a first and a second oscillating signals, mixing and adding in order to separate the in-phase and quadrature components of first and second signal from a combined radio frequency signal received as input.

摘要： An apparatus configured to separate from a received radio frequency (RF) signal a first low-frequency signal and a second low-frequency signal having different phases, up- convert the first low-frequency signal and the second low-frequency signal into a first intermediate frequency signal and a second intermediate frequency signal, respectively, and amplify the first and the second intermediate-frequency signals.
