RD70HVF1 MOSFET Power Transistor
From Free Knowledge Base- The DUCK Project: information for everyone
RD70HVF1 by Mitsubishi Electric Semiconductor is a Field Effect Transistor (High Power Si MOSFET) for amplification in the final stage of a radio transceiver. It is rated at 12.5V with an output of 70W.
The RD70HVF1 is a MOSFET, MOS-FET, or MOS FET made by Mitsubishi Corporation. It is specifically designed for VHF/UHF High power amplifier application.
Power rating:
- 70 watts at 175MHz
- 50 watts at 520MHz
High power and High Gain:
- Pout>70W, Gp>10.6dB @Vdd=12.5V,f=175MHz
- Pout>50W, Gp>7.0dB @Vdd=12.5V,f=520MHz
- Efficiency: 60%typ.on VHF Band
- Efficiency: 55%typ.on UHF Band
