SD2942 HF/VHF/UHF RF power N-channel MOSFET Datasheet - production data Features Gold metallization Excellent thermal stability Common source push-pull configuration POUT = 350 W min. with 15 dB gain 175 MHz Low RDS(on) Description Figure 1: Pin connection The SD2942 is a gold metallized N-channel MOS field-effect RF power transistor. The SD2942 offers 25% lower R than industry standard DS(ON) and 20% higher power saturation than ST SD2932. These characteristics make the SD2942 ideal for 50 V DC very high power applications up to 250 MHz.
