Microchip Announces New 5 GHz 50 ohm Matched WLAN Front End Module For IEEE 802.11a/n/ac Applications

Microchip SST11LF04

High-Efficiency and Compact SST11LF04 Provides Ultra High-Data-Rate for Mobile Device, Multi-Channel Access Point/Routers and Set-Top Box Equipment

Microchip Technology announced its new 5 GHz, 50 ohm Matched WLAN Front End Module (FEM) – the SST11LF04 – for high data rate mobile device 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 × 2.5 × 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.

Microchip - SST11LF04

This new 5 GHz 50 ohm matched FEM enables designers to create highly-efficient designs with smaller board size requirements, which reduces time to market. Its 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.
