MGFS38E2527: InGaP HBT Power Amplifier for WiMAX Terminals

Furthermore, the MGFS38E2527 provides a linear power gain of 35dB and allows off/on step attenuation of 0/25dB. These high values of output power and gain are achieved with low distortion of less than 2.5% EVM (Error Vector Magnitude) and a power detector output voltage of 1.5V, both at 28.5dBm. In accordance with the target applications (WiMAX) the new module operates in the frequency range 2.5 to 2.7GHz.

Integrated in a small package measuring just 4mm x 4mm the new MGFS38E2527 is 20% smaller than conventional amplifiers even though it already includes two functional circuits: a power detector for the precise monitoring of output power and a one-bit step attenuator for easy output power control. The new device is matched to 50Ω at the input and output.

By the end of March 2010 Mitsubishi Electric intends to introduce amplifiers for the 2.3GHz and 3.5GHz bands, which will also offer output powers of 28.5dBm.
