2.3-2.7GHz High Linearity Wi-Fi/WiMAX Power Amplifiers: MGA-43x28

The MGA-43228 and MGA-43328 High Linearity Wi-Fi/WiMAX PA modules have the same package footprint; pin-out and external matching network to allow a common printed circuit board (PCB) design when used at different frequencies. Additionally, this series of Power Amplifiers from Avago comes with an integrated bypass switch controlled attenuator which provides attenuation of ~24.0dB, along with a built-in power detector. In a typical operating environment of 5-volts and 1 Amp, the MGA-43228 delivers performance of 29.1dBm linear Pout at 2.5 percent error vector magnitude (EVM), 38.5dB gain and 16 percent PAE at 2400MHz. Under the same operating conditions, the MGA-43328 delivers a performance of 29.3dBm linear Pout at 2.5 percent EVM, 37.3dB gain and 16 percent PAE at 2600 MHz. These features enable the MGA-43x28 series Power Amplifiers to provide superior signal quality for computer performance evaluation (CPE) while transmitting at a higher throughput to reduce power consumption.
