The RF Line
NPN Silicon
RF Power Transistor
. . . designed primarily for applications as a high–power linear amplifier from 2.0
to 30 MHz, in single sideband mobile, marine and base station equipment.
• Specified 28 Volt, 30 MHz Characteristics —
Output Power = 80 W (PEP)
Minimum Gain = 15 dB
Efficiency = 40%
Intermodulation Distortion = –32 dB (Max)
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 Motorola 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.
