New fully-integrated front-end module (FEM) for high-power 802.11ac Internet of Things (IoT) applications

Engineers designing an IoT product are constantly aspiring to slash the size, design complexity, and cost of their products. One of the daunting challenges for designers is to add wireless connectivity. These design concerns can well be solved when you have the right ecosystem of solutions.

The new fully integrated Radio-frequency (RF) front-end modules (FEMs), SKY66113-11, from Skyworks aims to offer the required performance in compact size for IoT designers.

The FEM incorporates a 2.4 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 2.4 GHz low-noise amplifier (LNA) with bypass, and a 2.4 GHz power amplifier (PA) intended for high-power 802.11ac applications and systems, according to the announcement.

The LNA and PA disable functions ensure low leakage current in off mode. An integrated power detector is included to provide closed-loop power control within the system, the company said.

WLAN Module Product Highlights:

  • Providing 27dBM power out while drawing 555mA from a 5V supply, the SKY85309-11 serves access points, routers and gateways.
  • Transmit gain of 32dB improves SoC linearity.
  • Receive gain of 13dB with noise figure of 2.2dB improves receiver sensitivity and range.
  • Offered in a 3x5mm QFN package.

Applications:

  • 802.11ac networking and personal computing systems
  • PC cards, PCMCIA cards, mini-cards, and half mini-cards
  • WLAN-enabled wireless video systems

RFMW recently announced the design and sales support for the SKY66113-11.
