Avago Technologies today announced a front-end module with robust filtering for 802.11 b/g/n WiFi and Bluetooth radios in handsets and mobile routers for tablets and other portable PC devices. The new AFEM-S102 module integrates a Film Bulk Acoustic Resonator (FBAR) coexistence filter, SP3T antenna switch and TX path coupler in a small 2.2 by 2.2 by 0.55 mm package that is ideal for space-constrained applications. The 2.5 GHz module delivers superior out-of-band rejection enabling concurrent operation of WiFi and Bluetooth data-communication with cellular communication standards.

Avago front-end modules integrate multiple high-performance technologies to reduce PCB board footprint and simplify design for portable electronics applications. The AFEM-S102 module exhibits low insertion loss that combines with high noise rejection to meet stringent coexistence requirements and enable fewer interference issues between WiFi, Bluetooth and other radios. Effectively leveraging Avago 0.25 µm GaAs enhancement-mode pHEMT process and its leading-edge proprietary FBAR filtering technologies, the module delivers 2.6 dB maximum insertion loss for the TX path and 35 dB rejection in the 2110-2170 MHz range.

Avago FBAR technology delivers steeper roll-off and lower insertion loss than ceramic or SAW filters and other competing technologies, and does so in a more compact form factor. Low insertion loss reduces power amplifier current and improves receiver sensitivity and dynamic range, resulting in extended battery life and talk time and better signal quality for handsets. FBAR technology makes ultra-small, high-Q filters possible at a fraction of their usual size, and allows integration with other radio components.

Additional AFEM-S102 product features include:

* All RF ports matched to 50 ohms for simplified design

* TX, RX, BT and ANT ports DC blocked

* -18dB TX directional coupling

* -30° to +85° C operation.

The AFEM-S102 front-end module is priced at $1.00 each in 10,000 piece quantities. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.
