Abstract

1,019,751. Transistor mixers. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 15, 1962 [May 25, 1961], No. 18858/61. Heading H3T. [Also in Division H1 A resonant line coupler comprises three adjacent strip lines A, B, C, having a common ground such that coupling occurs between A and B, B and C, but not between A and C. The line may be tuned by small trimming capacitors. The coupler may be used in a transistor mixer circuit, the outer lines A, C receiving the signals to be mixed and the intermediate line B carrying the mixed signal.
