Front-End Modules

Qorvo presents a new series of high-linearity 2.5 GHz Front-End Modules (FEMs) built for automotive Wi-Fi applications, 802.11b/g/n, and Bluetooth^® systems. These devices feature integrated b/g/n power amplifiers, directional power detectors, RX balun, and TX filtering. Each FEM contains an ultra-small form factor and integrated matching that greatly reduces the number of external components and layout area in the customer application.

RFMD's RF6555 is a Front End Module (FEM) with a TX Output Power of 18 dBm, and a TX Gain of 25dB. It's ideal for WLAN and ZigBee® applications in the 2.4GHz to 2.5GHz band. In addition to its internal integrated LNA bypass mode, this FEM also integrates the PA plus harmonic filter in the transmit path. The RF6555 Front End Module provides a single balanced TDD access for RX and TX paths along with two ports on the output for connecting a diversity solution or a test port.

The SKY66112-11 is a 2.4 GHz fully integrated RF Front End Module (FEM) designed to deliver high performance in ZigBee®, Thread, And Bluetooth® Smart applications such as in-home appliances, smart thermostats, IoT devices, smart lighting, sensors, and range extenders.

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 Front End Module (FEM) is ideal for applications involving WiMAX, LTE TDD, Customer Premises Equipment (CPE), Data Card and Terminals, and Spread-Spectrum and MMDS Systems.

The SKY66113-11 is a 2.4 GHz fully integrated RF Front-end Module (FEM) designed to deliver high performance in Bluetooth Low Energy/Bluetooth Smart, 802.15.4, Thread, and ZigBee applications such as in smart thermostats, in-home appliances, beacons, gateways, sensors, and wearable devices.

The RF6504 Transmit/Receive Front End Module features 1 dB interface Rx insertion loss, a separate 50? Tx/Rx Transceiver, and 30 dBm Tx output power. Two separate ports can be found on the device (Rx and Tx) The Rx port is a pass through port, and the Tx section provides a PA with nominal output power of 30dBm and 15dB gain. Both combine to one antenna port with a SP2T switch.

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.
