DESCRIPTION:
The MS2205 is a gold metallized, silicon NPN power transistor
designed for pulsed applications with low duty cycles, such as
IFF, DME, and TACAN. It can withstand infinite VSWR under rated
conditions. The MS2205 is housed in the .250" input-matched
stripline package, resulting in improved broadband performance
and low thermal resistance.
