Abstract

A HIGH FREQUENCY TRANSISTOR IS DESCRIBED HAVING INPUT, OUTPUT AND COMMON LEADS. IN ORDER TO REDUCE THE UNDESIRED FEEDBACK EFFECT OF A STRAY SERIES INDUCTANCE IN THE COMMON LEAD, THE OUTPUT LEADS ARE ARRANGED SO AS TO CROSS ONE ANOTHER IN SUCH CLOSE PROXIMITY AS TO INDUCTIVE-

LY COUPLE THEM TOGETHER PROVIDING A FEEDBACK OPPOSITE TO THAT OF THE STRAY INDUCTANCE IN ORDER TO COMPENSATE THE LATTER.
