Avago Technologies recently announced two high-linear power-amplifier (PA) modules that were optimized for low power consumption and improved signal quality in 2GHz WiMAX, WiFi, and LTE applications. Housed in a miniature 5 by 5 by 0.85 mm package, the PA is well suited for use as a final stage PA in high-power applications in the 2300 to 2700MHz range.

The MGA-43x28 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 PAs 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 PAs to provide superior signal quality for computer performance evaluation (CPE) while transmitting at a higher throughput to reduce power consumption.
