High-Voltage,High-Power Transistors. Characteristics of Developmental Units.

摘要

Lot number 4 of 27 units, designated TA1801 developmental samples, have been received by NRL on ONR contract No. NOnr-2478(00). These units have been tested for breakdown and output characteristics, and tabular and photographic data are presented. A curve-tracing circuit which will give common-base and common-emitter (with base open or shorted) characteristics is described. Also described are the modifications to a curve tracer for output characteristics and a test power-amplifier circuit.
