RF5725 - 3.3 V, Single-Band Front-End Module

RF5725 - 3.3 V, Single-Band Front-End Module

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.

802.11ac Enabling Front-End-Modules

802.11ac Enabling Front-End-Modules

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.

WLAN 802.11n 1 x 2 SIMO Front-End Module -  SKY65240-11

WLAN 802.11n 1 x 2 SIMO Front-End Module - SKY65240-11

The SKY65240-11n FEM combines one complete dual-band transmit chain and two complete dual-band receive chains in one compact RF front end module optimized for 1 x 2 SIMO (Single In - Multiple Out) operation, in compliance with the 802.11n draft standard. The SKY65240-11 includes one 5 GHz PA and one 2 GHz PA, each with integrated input filtering for 3–4 GHz rejection, and two temperature- compensated, directional power detectors with 20 dB dynamic range. Also included are low loss, high rejection GaAs diplexers and switches which provide high linearity in all transmit paths and low loss in all receive paths. All RF ports are matched to 50 Ohm.

5 GHz Front-End-Module: SKY85716-11

5 GHz Front-End-Module: SKY85716-11

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.

Wi-Fi Front End Modules

Wi-Fi Front End Modules

RF Micro Devices, Inc. recently expanded its Wi-Fi product portfolio to include three new front end modules (FEMs): the RF5325, RF5345 and RF5725. The highly integrated FEMs are designed to address the need for high performance and continued size reductions in mobile Wi-Fi applications, including handsets, personal navigation devices (PNDs), digital cameras and MP3 players.
3.6V, Single-Band Front End Module: RFFM3482E

3.6V, Single-Band Front End Module: RFFM3482E

RFMD's RFFM3482E is a single-band front end module (FEM) ideal for applications involving IEEE802.11b/g/n WiFi, 2.5GHz ISM Bands, portable battery-powered equipment, WiFi systems, and more. Its size is ideal for a 802.11b/g/n front end design and greatly reduces the number of components outside of the core chipset. This FEM has the ability to switch between WiFi Rx, WiFi Tx, and BTH Rx/Tx operations. An Rx balun, a b/g/n power amplifier, and a directional power detector have all been integrated into the RFFM3482E.
