Method for forming an intermediate frequency signal in a mixer, and a mixer

摘要

The invention relates to a method for forming at least two intermediate frequency signals with different phases in a mixer ( 1 ), to which a first signal (RF) and a second signal (LO) are conducted. According to the method, the first intermediate frequency signal is formed by shifting the phase of the first signal (RF) and by mixing the phase-shifted first signal (RF) and the second signal (LO). The second intermediate frequency signal is formed by mixing the first signal (RF) and the second signal (LO). The phase shift of the first signal (RF) is performed in the mixer ( 1 ).
