MOTOROLA The RF Line SEMICONDUCTOR TECHNICAL DATA Order this document by MRF455/D 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 Motorola 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 th...
