PROBLEM TO BE SOLVED: To enhance the integration degree of a receiver and to make the size of the receiver small by decreasing the size of a mixer an integrated circuit application. SOLUTION: In the method for forming at least two intermediate frequency signals of different phases in a mixer (1), a first signal (RF) and a second signal (LO) are transferred to this mixer. In accordance with this method, first intermediate frequency signal is formed by phase shift of the first signal (RF), then the first signal (RF) being phase shifted is mixed with the second signal (LO). The second intermediate frequency signal is formed by mixing the first signal (RF) with the second signal (LO). The phase shift of the first signal (RF) is executed in the mixer (1).
