SEMICONDUCTOR TECHNICAL DATA

The RF Line

. . . 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

80 W (PEP), 30 MHz

RF POWER

TRANSISTOR

NPN SILICON

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 h

at the

data sheet conditions and color coding the device to predetermined h ranges

within the normal h

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.
