Mitsubishi Electric to Ship InGaP HBT Power Amplifier for WiMAX Terminals

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today the sale of a new InGaP HBT[1] power amplifier, the MGFS38E2527, for use in WiMAX[2] subscriber terminal equipment. The module, which measures just 4 mm x 4 mm, produces high output power of 28.5 dBm[3] with low distortion. Sample shipments will commence on January 25, 2010.

WiMAX is growing increasingly popular for high-speed wireless communications use due to its extra wide area coverage compared to that of existing high-speed wireless services. To extend the communication range between WiMAX base stations and terminals, there is a growing need for compact power amplifiers for installation in WiMAX terminals such as PC cards and customer premises equipment. Such amplifiers are required to deliver high output with low distortion, while maintaining high radio signal quality.

In the past, Mitsubishi Electric has released a series of InGaP HBT power amplifiers — the small-size MGFS36Exxxx for WiMAX terminals used in mobile and fixed-line communications, and the MGFS39Exxxx, which features industry-leading output power combined with low distortion.

The company now adds the new MGFS38E2527 power amplifier to this lineup. Compared to existing models, this newest amplifier provides more power and less distortion in a smaller package.

Product Features

1) High power with low distortion for wider coverage

The new amplifier achieves low distortion of less than 2.5% EVM[4] at a high maximum output of 28.5 dBm. Output power is 1.5 dB[5] higher than that of the existing MGFS36E2527 [6], which will enable both wider service areas and improved signal quality for WiMAX systems.

2) Small 4 mm x 4 mm package, including peripheral functional circuitry

The amplifier is produced in a small 4 mm x 4 mm package, which is 20% smaller than that of conventional amplifiers. It includes two functional circuits: a power detector for precise monitoring of output power, and a one-bit step attenuator for easy control of output power. Matching 50 Ω input and output circuits are integrated into the amplifier, eliminating the need for additional matching circuits on the customer’s board. The amplifier is expected to reduce both the occupied board area and the number of surface-mounted devices, consequently contributing to the development of smaller, lighter WiMAX terminals.

Future Developments

Mitsubishi Electric plans to develop 2.3GHz- and 3.5GHz-band amplifiers offering an output of 28.5 dBm by the end of March 2010.
