Module incorporates power amplifier, path coupler and antenna switch
14 February 2012
New Avago Technologies front-end module offers best-in-class efficiency for WiFi 5GHz access points.
Avago Technologies, a supplier of analogue interface components for communications, industrial and consumer applications, has announced a highly efficient front-end module for WiFi access points.
The new AFEM-S105 module integrates a power amplifier, directional coupler, and SPDT antenna switch in a small-footprint 3.2 by 3.2 by 0.6 mm package.
The power amplifier is optimised for IEEE 802.11 a/n WiFi modulation, helping the module streamline design of mobile and fixed wireless data applications in the 5.15 to 5.85 GHz frequency range.
Avago front-end modules integrate multiple high-performance technologies to reduce PCB board footprint and simplify design. The AFEM-S105 module leverages the company’s proprietary 0.25 µm GaAs enhancement-mode pHEMT process technology to achieve robust RF performance across voltage and temperature levels, as well as low current consumption.
The module exhibits flat gain and good match while providing linear power efficiency to meet stringent 802.11a/n mask conditions.
“Designers are under tremendous pressure to integrate WiFi connectivity to bring new products to market first,” said James Wilson, Director of Marketing for wireless products at Avago. “Our easy-to-use AFEM-S105 front-end module provides a highly-integrated, compact solution that can be quickly designed in to WiFi access points and portable WiFi applications.”
Additional AFEM-S105 product features include:
• All RF ports matched to 50 ohms for simplified design
• High Tx - Rx switch isolation
• Gain of 28 dB
• Stable under all loads or conditions
• Meets FCC 15.205 emission requirements at 15 dBm
Samples and production quantities are available now through Avago’s direct sales channel and worldwide distribution partners.
