Power Amplifier for WiMAX from Mitsubishi Electric

MGFS39E2527 offers an integrated power detector for 1.1V at the amplifier output while a step attenuator controls the output within a range of 18dB. The new device, which is integrated in a QFN package measuring 6 mm x 6 mm, keeps the EVM (error vector magnitude) as low as 2.5% at 30dBm while the total linear power gain is 40dB. The IC operates with a supply voltage of 6V and a reference voltage of 2.85V.

While the MGFS39E2527 offers already a 3dB improvement in terms of output power (compared to Mitsubishi Electric’s previous Model MGFS36E2527), the company is already developing an amplifier for the 3.5GHz band with an output power of 30dBm whose introduction is planned for the end of this year.
