Description
The SD2943 is a gold metallized N-Channel MOS
field-effect RF power transistor. It is intended for
use in 50 V dc large signal applications up 150
MHz. SD2943 offers a 20% higher power
saturation than SD2933, it is idea for ISM
applications where reliability and ruggedness are
critical factors.
