The RF5725 is a single-chip integrated front-end module (FEM) for high performance WLAN applications in the 2.4GHz to 2.5GHz ISM band. This FEM greatly reduces the number of external components, minimizing footprint and assembly cost of the overall 802.11b/g solution. The RF5725 has an integrated b/g power amplifier, LNA, a Coupler Power detector, and TX filtering. It also is capable of switching between WLAN RX, WLAN TX, and BTH RX/TX operations. This device is manufactured using GaAs HBT and pHEMT processes on a 3mmx3mmx0.5mm 16-pin QFN package. This module meets or exceeds the RF front-end needs of 802.11b/g WLAN RF systems.
IEEE 802.11ac enables faster content downloads than 802.11n solutions have in the past. Skyworks recently developed and released two from-end-modules (FEMs) that enable 802.11ac technology for WiFi enabled smartphones and tablets. These new FEMs allow consumers to experience incredibly fast download speeds across multiple platforms.
This fully matched front-end-module (FEM) comes with an integrated 5 GHz power amplifier with harmonic mode, and a low noise amplifier with bypass mode and an SPDT switch. It’s designed for WiFi-enabled handsets/tablets, system-in-package (SIP) modules for embedded systems, and 802.11n/ac smartphones and tablets.
