Wireless data power amplifiers for WiMAX and WiFi applications
1 min read
Avago Technologies has announced two new high linear power amplifier (PA) modules which it says feature low power consumption and improve signal quality for WiMAX and WiFi applications that operate in the 2GHz range.
The PA series features high linear Pout for good linearity and low distortion, high power added efficiency (PAE), as well as input and output prematch for matching and application simplicity. The MGA-43x28 PA module series, which is housed in a 5 x 5 x 0.85mm package, are suitable for use as a final stage PA in a range of high power WiMAX, WLAN and LTE applications which operate in the 2300 to 2700MHz spectrum.
The MGA-43x28 PA modules have the same package footprint, pin-out and external matching network to allow a common pcb design when used at different frequencies. This series 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 5volts and 1Amp, the MGA-43228 is said to deliver performance of 29.1dBm linear Pout at 2.5% error vector magnitude (EVM), 38.5dB gain and 16% PAE at 2400MHz.
Under the same operating conditions, the MGA-43328 is designed to deliver a performance of 29.3dBm linear Pout at 2.5% EVM, 37.3dB gain and 16% PAE at 2600 MHz.
Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
