MATCHING PROCEDURE
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 hFE 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.
