SD2943

HF/VHF/UHF RF power N-channel MOSFETs

Features

■ High power capability

■ POUT = 350 W min. with 22dB gain @ 30 MHz

■ PSAT = 450 W

■ Low RDS(on)

■ Thermally enhanced packaging for lower

junction temperatures

■ Gold metallization

■ Excellent thermal stability

■ Common source configuration

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 to 150

MHz. The SD2943 offers a 20% higher power

saturation than the SD2933, and is ideal for ISM

applications where reliability and ruggedness are

critical factors.
