Skyworks Launches 2.4 GHz WLAN Front-end Module for IoT Applications

21 June 2018

Skyworks is pleased to introduce the SKY85309-11, the industry’s highest power, fully integrated front-end Source: SkyworksSource: Skyworksmodule (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.


  • 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: 12 dB
  • Output power: +22 dBm @ 1.8 percent EVM, HT40, MCS9, 5 V
  • Output power: +24 dBm @ 3 percent EVM, HT40, MCS7, 5 V
  • Small, QFN (24-pin, 3 x 5 mm) package (MSL3, 260 degrees Celsius per JEDEC J-STD-020)
