Avago Technologies, a supplier of analog interface components for communications, industrial and consumer applications unveiled two new high linear power amplifier modules.
 
These power amplifier or PA modules feature characteristics like low power consumption and better signal quality for WiMAX (News - Alert) and Wi-Fi applications that operate in the 2GHz range. They also ensure high linear Pout for good linearity and low distortion, high power added efficiency or PAE, as well as input and output pre-match for matching and application simplicity.
 
Avago sources added that the MGA-43x28 PA module series, which are housed in a miniature 5 x 5 x 0.85 mm package, are most suitable to be used as a final stage PA in several high power WiMAX, WLAN and LTE (News - Alert) applications which operate in the 2300 to 2700 MHz spectrum.
 
The new modules allow a common printed circuit board design even when used at different frequencies. This series of PAs from Avago integrates a bypass switch controlled attenuator providing attenuation of ~24.0dB, along with a built-in power detector.
 
The optimized features of the MGA-43228 and MGA-43328 power amplifier modules enable them to provide superior signal quality for computer performance evaluation or CPE while transmitting at a high throughput to bring down power consumption.
 
The small form factor modules feature advanced GaAs E-Phemt technology. Its 5V power supply can be used at 3.3V for low supply voltage applications. It also has built-in detector and shutdown switches, and is lead free. Company sources added that samples and production quantities are available now via Avago’s direct sales channel and global distribution partners.
 
Avago Technologies supplies analog interface components for communications, industrial and consumer applications. The company capitalizes its core competencies in III-V compound and silicon semiconductor design and processing to offer an extensive range of analog, mixed signal and optoelectronics components and subsystems serving about 40,000 end customers.
 
The company’s products and customer service makes it a preferred supplier by diverse end markets such as wireless communications, wired infrastructure, industrial and automotive electronics, and consumer and computing peripherals.
