The TQF9046 from TriQuint is a complete WLAN front-end module in an ultra small 2.5 mm x 2.5 mm footprint package for 802.11b/g/n + BT applications. It comprises a 2.4 GHz PA, directional detector, front-end SP3T switch, and LNA with bypass mode.

The device also features internally matched input/output and temperature compensated bias network. The architecture and interface are optimized for next generation WLAN integration into handset devices.

The front-end module features CMOS compatible control voltages to facilitate ease of use. With its low power dissipation, the front-end Module contributes to the extended battery life of next generation WLAN solutions.

The front-end module is manufactured in TriQuint's high-reliability E/D pHEMT technology and is assembled in ultra thin profile 2.5 mm x 2.5 mm x 0.40 mm QFN, 16 Pb-free package.

The TQF9046 requires a single battery voltage of 3.2 V to 5.0 V. Typical Pout ( at +25°C and VDD of +3.6 V) is 19.3 dBm with EVM of 3.0% — 802.11n/MCS7. Typical Pout (at +25°C and VDD of +3.6 V) is 20.2 dBm with EVM of 4.6% — QAM64, 54 Mbps OFDM.

Typical applications include automotive telematics, handsets, M2M, module integrators, portable applications and tablets.
