Oki Electric Develops Power GaAs MESFET with World's Highest Drain Efficiency
Tokyo (4/20) - Oki Electric Industry announced that it has developed the KGF1934, a power gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) for 10W-level wireless communications.
The device achieves the industry's highest drain efficiency of over 55% with an output power of 10W at a compression point of 1db.
It also marks 25% in drain efficiency at the normal operating output power level of 2W.
Oki will start shipping the device in sample quantities this month, targeting applications including transmitter power amplifiers for W-CDMA and CDMA2000 wireless base stations.
The company will launch commercial production in June, aiming to ship 10,000 units per month.
