suppression mixer frequency circuit including a radio receiver for frequency zero intermediate frequency or weak.

摘要

mixer circuit for suppressing frequency image comprising a divider quadrature phase (30, 301) having an input connected to the (LAN) mixer input circuit and two outputs delivering respectively two signals in phase quadrature which are respectively applied to two simple mixers (31, 32; 31¿, 32¿), comprising a frequency divider and quadrature phase (33, 33¿) having a frequency division ratio, and has two inputs respectively connected to the respective outputs of the simple mixers (31, 32; 31¿, 32¿) and a first output the Minister a first output signal (F0) of the mixer circuit, which applies in the entrance of two simple mixers .
