Avionics 1025-1150 MHz

GENERAL DESCRIPTION

CASE OUTLINE

55AW Style 1

The DME375A is a high power COMMON BASE bipolar transistor. It is

designed for pulsed systems in the frequency band 1025-1150 MHz. The device

has gold thin-film metallization for proven highest MTTF. The transistor

includes input and output prematch for broadband capability. Low thermal

resistance package reduces junction temperature, extends life.
