5GHz WLAN FEM extends IEEE 802.11a range
Designed for high data-rate mobile device applications, Microchip's SST11LF04 WLAN Front End Module (FEM) extends the range of IEEE 802.11a WLAN systems, while providing exceptional transmit power at the maximum 11ac high-data-rate modulation. Offered in one integrated, compact 2.5x2.5x0.4 mm, 16-pin QFN package, the FEM features a transmitter power amplifier, a receiver low-noise amplifier with bypass and a low-loss, single-pole two-throw antenna switch for 5GHz WLAN connectivity.
The device features a 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 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 5GHz 50 Ohm matched FEM enables designers to create efficient designs with smaller board size requirements, with a reduced time to market. The FEM'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.
