发明名称 IMAGE REJECTION FREQUENCY CONVERTER PROVIDED IN PLANAR TECHNOLOGY
摘要 There is described an image rejection frequency converter comprising essentially a balun (DIV) used as a power divider for coupling a local oscillator signal to the ends of two frequency mixers (MIX1, MIX2). Said mixers (MIX1, MIX2) have ports to which arrive or from which come out intermediate radiofrequency signals (Fig. 1). The invention consists principally of integration of the power divider (DIV) and the mixers (MIX1, MIX2) in a planar structure based on a new concept provided in microstrip and in coplanar line. <IMAGE>
