INPUT/OUTPUT MATCHING
COMMON BASE CONFIGURATION
DESCRIPTION:
The MS2441 is a silicon NPN power transistor designed
for high peak power and low duty cycles applications such as
DME and IFF. The MS2441 utilizes internal input/output
impedance matching, resulting in improved broadband
performance and a low thermal resistance.
