Avago Technologies announced a complete RF front-end
module (FEM) for WiMAX radios in mobile handset or portable PC applications.
The new AFEM-S257 module is designed specifically for coexistence operation
of WiMAX with other cellular and WiFi radios in the same device. The module
features two receive ports and a single transmit port in a small 5 by 7 by 1 mm
package that is ideal for space-constrained mobile applications in the 2.5 to
2.7 GHz frequency range – providing up to 25 percent space savings over
discrete WiMAX solutions.
The AFEM-S257 module integrates multiple high-performance
technologies to reduce PCB board footprint, while simplifying design and
manufacturing and shortening time to market. Utilizing Avago proprietary
0.25-µm GaAs enhancement-mode pHEMT process and leading-edge Film Bulk Acoustic
Resonator (FBAR) filtering technologies, the module delivers superior
performance across voltage and temperature levels.
Avago Technologies’ FBAR
technology delivers steep roll-off and low insertion loss, resulting in
extended battery life and talk time and better signal quality. With high noise
rejection of 35 dBc, the module enables fewer interference issues between IEEE
802.16 WiMAX and other radios. The AFEM-S257 module achieves 24 dBm of
WiMAX-compliant output power, while maintaining an error vector magnitude (EVM)
of 2.5 percent at 16 quadrature amplitude modulation (QAM).
The AFEM-S257 front-end module provides a complete,
compact solution that can be easily and quickly designed in to mobile WiMAX
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. With Avago FBAR filtering technology delivering
unparalleled out-of-band rejection, the module offers the performance major
smartphone makers demand.”
The AFEM-S257 WiMAX coexistence front-end module is
available in a 28-lead MCOB package and is priced at $9.50 each in 10,000 piece
quantities. Samples and production quantities are available now through the
Avago direct sales channel and via worldwide distribution partners.
