GENERAL DESCRIPTION
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.
