The MGA-445940-02 is a power amplifier with the State-of-the-Art linear power-added-efficiency between 4.4 GHz and 5.9 GHz frequency band. Based on advanced robust GaN device technology, the power-added-efficiency of this power amplifier is as high as 25% when it outputs 2W linear burst power with 2.5% EVM under the 802.16d/e 64QAM modulation schemes. The high efficiency linear power amplifier also has excellent reliability. Ideal applications include the driver and the output power stage of WLAN infrastructures and access points. It also can be used for PTP (Point-To-Point) radio applications for this band.
