The RF Line
NPN Silicon
RF Power Transistor
. . . designed for power amplifier applications in industrial, commercial and
amateur radio equipment to 30 MHz.
• Specified 12.5 Volt, 30 MHz Characteristics —
Output Power = 60 Watts
Minimum Gain = 13 dB
Efficiency = 55%
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.
