2.4 GHz WLAN front-end module released by Skyworks

Skyworks has introduced the SKY85309-11, the highest power, fully integrated front-end module (FEM) for 802.11ac Internet of Things (IoT) applications.

The FEM incorporates a 2.4 GHz single-pole, double-throw (SPDT) transmit/receive switch, a low-noise amplifier with bypass and a power amplifier. It features high gain (32 dB) to improve system-on-chip (SoC) linearity and includes a receive filter port for co-existence filters without loss on the transmit path.

The FEM reduces costs by meeting maximum FCC EIRP requirements with only two streams and comes in a compact, 24-pin 3 x 5 mm Quad Flat No-Lead (QFN) package. This feature-rich device is ideal for IoT applications including access points, routers and gateways.

**Features **

  • Integrated high-performance 2.4 GHz PA, LNA with bypass, and T/R switch

  • Fully matched input and output

  • Integrated power detector and directional coupler

  • Transmit gain: 32 dB

  • Receive gain: 13 dB

  • Output power: +22 dBm @ 1.8% EVM, HT40, MCS9, 5 V

  • Output power: +24 dBm @ 3% EVM, HT40, MCS7, 5 V

  • Small QFN (24-pin, 3 x 5 mm) package
