WLAN front end module supports IEEE 802.11a/n/ac applications
The SST11LF04 features a transmitter power amplifier, a receiver low-noise amplifier with bypass and a low-loss, single-pole two-throw antenna switch for 5 GHz WLAN connectivity into one integrated, compact 2.5 x 2.5 x 0.4 mm, 16-pin QFN package, making it ideal for high-data-rate mobile device applications.
With its small footprint, high linear output power of up to 16 dBm and 17 dBm, at 3.3V and 5V Vcc respectively — for 1.75% dynamic EVM using MCS9-HT80 modulation and 80 MHz bandwidth along with 18 dBm and 19 dBm linear power for 3% EVM at 3.3V and 5V, respectively — the SST11LF04 extends the range of IEEE 802.11a WLAN system while providing exceptional transmit power at the maximum 11ac high-data–rate modulation. The receiver has a 12 dB gain and a greater than -6 dBm input (1 dB) compression level. In LNA bypass mode, the receiver has a 2.5 dB noise figure and an -6 dBm input compression level.
The 5 GHz 50 ohm matched FEM enables designers to create highly-efficient designs with smaller board size requirements, which reduces time to market.
The device’s high linear power enables 802.11a/n/ac operation and increases data rates, while its small size is ideal for space-constrained applications including mobile devices, multi-channel access point/routers and set-top boxes.
The SST11LF04 is available today for sampling and volume production, in a 2.5×2.5×0.4 mm, 16-pin QFN package.
