Avago Technologies Announces New AFEM-S257 Module

By Deepika Mala, TMCnet Contributor


Avago Technologies, a premier supplier of analog interface components for communications, industrial and consumer applications, has introduced the new AFEM-S257 module for WiMAX radios in mobile handset or portable PC applications.

Designed specifically for coexistence operation of WiMAX with other cellular and WiFi (News - Alert) radios in the same device, the complete RF front-end module, features two receive ports and a single transmit port in a small 5 by 7 by 1 mm package.


“The AFEM-S257 front-end module provides a complete, compact solution that can be easily and quickly designed in to mobile WiMAX (News - Alert) applications, which is demonstrated in the top three reference designs addressing this market,” said James Wilson, senior director of marketing for wireless products at Avago, in a press release.

To reduce PCB board footprint, the AFEM-S257 module integrates multiple high-performance technologies. The module utilizes Avago proprietary 0.25-µm GaAs enhancement-mode pHEMT process and leading-edge Film Bulk Acoustic Resonator filtering technologies.

By utilizing the same, it is capable of delivering superior performance across voltage and temperature levels.

“With Avago FBAR filtering technology delivering unparalleled out-of-band rejection, the module offers the performance major smartphone makers demand,” adds Wilson.

The module, with high noise rejection of 35 dBc enables fewer interference issues between IEEE 802.16 WiMAX and other radios. It achieves 24 dBm (News - Alert) of WiMAX-compliant output power, and at the same time also maintains an error vector magnitude of 2.5 percent at 16 quadrature amplitude modulation.

Additional benefits of the module include: 3 to 5V power supply for TX path, 18 percent power added efficiency, 3.5 dB Noise Figure from ANT to RX and others.

Avago will demonstrate the module live and will exhibit its complete RF and Microwave portfolio, at the 2011 IEEE (News - Alert) Microwave Theory & Techniques Society International Microwave Symposium.

In related news, Avago Technologies has announced the sale of 25,000,000 ordinary shares by selling shareholders.
