SD2933
HF/VHF/UHF RF power N-channel MOSFETs
Features
■Gold metallization
■Excellent thermal stability
■Common source configuration
■POUT = 300 W min. with 20 dB gain @ 30 MHz
■Thermally enhanced packaging for lower
junction temperatures
Description
The SD2933 is a gold metalized N-channel MOS
field-effect RF power transistor, intended for use
in 50 V dc large signal applications up to 150
MHz. Its special low thermal resistance package
makes it ideal for ISM applications, where
reliability and ruggedness are critical factors.
