Mitsubishi eyes WiMAX with new InGaP HBT
Low-distortion, high-power amplifier to begin sampling on August 20, with Mitsubishi aiming to manufacture 100,000 devices per month
TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (President and CEO: Setsuhiro Shimomura) announced today the development of a high-power amplifier with InGaP HBT, the MGFS39E2527, for fixed-line WiMAX communication terminals in subscriber lines. The amplifier achieves top-level performance with high output power and low distortion. Sample shipment begins August 20, 2008.
While adoption of broadband communication services is increasing in urban areas, WiMAX is garnering increasing attention for its ability to transmit signals up to 50 kilometers and be applied in areas where installations of broadband communication services are difficult. With WiMAX communication terminals in subscriber lines, there is a demand for a high power transceiver amplifier with low distortion in order to cover a wider WiMAX service area.
Mitsubishi Electric has until now developed and supplied high power amplifiers for mobile and fixed-line WiMAX terminals, including the Pre-WiMAX high power amplifiers for the United States. The new MGFS39E2527 is a high power amplifier for WiMAX communication terminals in subscriber lines, achieving low distortion and high output power of 1 watt, which is top-level in the industry.
Product Features
* High power and low distortion, enabling coverage over a wider WiMAX service area
* The 6 mm x 6 mm QFN3 package with low thermal resistance enables operation at high output power. In addition, the optimized circuit with its impedance matched to OFDM (Orthogonal Frequency Division Multiplexing), a modulation technique in the WiMAX system, keeps EVM as low as 2.5%. These developments helped achieve an industry top-level high output power of 30dBm, a 3dB improvement compared to our previous model.
* Quad Flat Non-leaded integrated circuit package used with surface mounted printed circuit boards. The leads do not extend out from the sides of the package; instead, the contacts are on the bottom.
* Error Vector Magnitude, an index that shows the accuracy of the modulation signal.
* A unit of power; 30dBm=100mW.
* MGFS36E2527
* Built-in power detector and attenuator helps decrease components and surface-mounting space
* The new MGFS39E2527 has a built-in power detector, which detects output from the amplifier, and a step attenuator, which controls the output. The built-in power detector and attenuator help decrease components, surface-mounting space and cost in WiMAX communication terminals.
Future Developments
Mitsubishi Electric plans to develop a 3.5GHz-band amplifier with an output power of 30dBm by the end of 2008.
