Mitsubishi Electric to Launch 3.6V High-power MOSFET for Commercial Two-way Radio Devices

TOKYO, August 28, 2014 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that from September 1 it will begin shipping samples of its model RD04LUS2 high-power metal-oxide semiconductor field-effect transistor (MOSFET), which is designed for use in high-frequency power amplifiers of commercial two-way radio devices. The model offers industry-leading 4W output when using a 3.6V Li-ion 1-cell battery. Mitsubishi Electric will initially produce 200,000 units per month.


While the popularization of mobile phones has led to 3.6V Li-ion batteries costing less than traditional 7.2V batteries, the need for a higher-power MOSFET arose because lower-voltage batteries decrease the MOSFET's output power. Mitsubishi Electric has now met this demand with its new MOSFET, which offers unmatched 4W output power using a 3.6V battery.
1) Industry's highest power output
-Using a high-density layout for its new MOSFET, Mitsubishi Electric has achieved an industry-leading 4W power output under 3.6V operation, representing a 74% improvement over the company's predecessor, the RD02LUS2.
-High-power output extends radio transmission distances when using a 3.6V Li-ion 1-cell battery.
2) Top-level 65% drain efficiency
-The optimized MOSFET structure enables the RD04LUS2 to offer top-level 65% drain efficiency at 527 MHz.
-Low power consumption extends the available duration of radio transmission.
