Tokyo, July 30, 2008 －D-Clue Technologies CO., LTD. (CEO Akihiko Ishikawa) succeeded to develop the low power consumption technology to solve power consumption problem of Mobile WiMAX.
   D-Clue technologies had released 3.3V high performance WiMAX power Amplifier DC11 series (DC1102A:2.5GHz, Dc1103A:3.5GHz) in the market. This time we develop new HiPAE technology that achieves low power consumption for Mobile WiMAX Power Amplifier by using SiGe process.
   Our first HiPAE technology Power Amplifier DC12 series, DC1202:2.5GHz and DC1203:3.5GHz delivers 25% Industry Leading PAE (Power Added Efficiency) at 24dBm output power with 3.3V supply voltage. This high efficiency realizes the lowest power consumption and the longest battery operation to Mobile WiMAX equipment.
   HiPAE technology DC1202 and DC1203 will start sample shipping from October to our leading customers. Production is planning to start in 1Q 2009.
   D-Clue technologies have been developing high performance Power Amplifier for Mobile WiMAX and WiMAX RF application based on our high performance Power Amplifier technology and our first High power linear Power Amplifier DC1101(released in 2004) technology. New HiPAE technology is major result and drives to innovate WiMAX network capability to all mobile equipment, including Note PC, PDA, Cell phone, PND, and realize the ubiquitous network world.
   "This high efficiency Power Amplifier enables the lowest power consumption and longest battery operation to service Mobile WiMAX equipment. We continue to target low power consumption and high efficiency products for Mobile WIMAX, LTE and future next generation wireless communications," said Akihiko Ishikawa, CEO, D-Clue Technologies.
