In the push–pull circuit configuration it is preferred that the transistors are used as matched pairs to obtain optimum performance. The matching procedure used by M/A-COM consists of measuring h FE at the data sheet conditions and color coding the device to predetermined hFE ranges within the normal hFE limits. A color dot is added to the marking on top of the cap. Any two devices with the same color dot can be paired together to form a matched set of units.
