Mitsubishi Electric Announces Sale of 'MGFS39E2527' High Power InGaP HBT Amplifier for WiMax Terminals

TOKYO--(Business Wire)--
Mitsubishi Electric Corporation (President and CEO: Setsuhiro
Shimomura) announced today the development of a high power amplifier
with InGaP HBT,(1) the MGFS39E2527, for fixed-line WiMAX(2)
communication terminals in subscriber lines. The amplifier achieves
top-level performance with high output power and low distortion.
Sample shipment begins August 20, 2008.

1: Indium Gallium Phosphide Heterojunction Bipolar Transistor,
which features high efficiency operation for mobile phone
applications.

2: Worldwide Interoperability for Microwave Access, a high-speed
wireless communication system with a range of 50 kilometers.

Aim of Sale

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

1) High power and low distortion, enabling coverage over a wider
WiMAX service area

The 6 mm x 6 mm QFN(3) 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(4) as low as 2.5%. These developments helped achieve an industry
top-level high output power of 30dBm(5), a 3dB improvement compared to
our previous model.(6)

3: 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.

4: Error Vector Magnitude, an index that shows the accuracy of the
modulation signal.

5: A unit of power; 30dBm=100mW.

6: MGFS36E2527

2) 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.
