GaInP HBT Amplifier Module targets WiMAX terminals.

Modern modulation principles used with the WiMAX standard primarily demand a high linearity of the transmission signal. By using the GaInP HBT amplifier module from Mitsubishi, which is specifically tailored to WiMAX applications, the output power can be increased to 27dBm while the error vector magnitude (EVM) remains less than 2.5%. The module provides gain of 32dB. When used with 64 QAM (quadrature amplitude modulation) the amplifier module achieves excellent linearity up to an output power of more than 27dBm (referring to 500mW). This allows for the use in fixed installation WiMAX terminals according to IEEE802.16-2004 as well as in mobile WiMAX devices according to IEEE802.16e-2005.

With a footprint of just 4.5mm x 4.5mm and an overall height of just 1mm the MGFS36E2527 is the world's smallest amplifier in its class. Furthermore, the device contains a power detector for controlling the output signal as well as a voltage-controlled stepped attenuator providing 20 dB attenuation. No other external matching components are needed as the module is directly matched to 50Ω at the input and output terminals. This reduces the number of components required resulting in smaller final products of reduced weight.

MGFS36E2527 operates in the frequency range from 2.5 to 2.7GHz from a single 6V power supply. In addition to this amplifier module Mitsubishi Electric offers further WiMAX devices for the frequency ranges of 2.3 to 2.5GHz as well as for the European frequency range of 3.4 to 3.6GHz.
