DESC RIPTION
The SD1538-02 is a gold metallized silicon, NPN
power transistordesignedfor applications requiring
high peak power and low duty cycles such as
IFF, DME and TACAN. The SD1538-02 is packaged in a metal/ceramic package with internal
input/output matching resulting inimproved broadband performance and a low thermal resistance.
