Order this document by MRF455/D SEMICONDUCTOR TECHNICAL DATA The RF Line . . . 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% 60 W, 30 MHz RF POWER TRANSISTOR NPN SILICON 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 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 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.
