Front-End Modules

Qorvo offers a front end module (FEM) and two low noise amplifiers (LNAs) designed specifically for Wi-Fi applications such as access points and wireless routers.

The SKY85748-11 is a 5 GHz WLAN Front-End Module (FEM) with an integrated log detector that is ideal for 802.11ax networking and personal computing systems, PC cards, PCMCIA cards, mini-cards, half mini-cards, and WLAN-enabled wireless video systems.

pSemi offers the PE53211 highly integrated front-end module targeted for wireless infrastructure applications such as TDD macro/micro base station, MIMO, 4G, 5G, or small cell applications. The dual-channel receiver integrates two independent LNAs with bypass function and a high-power switch. The module can operate across the 2.3 – 2.7 GHz frequency range with internal impedance matching networks.

The SKY66111-11 is a highly integrated front-end module (FEM) from Skyworks operating in the 2.4 to 2.485 GHz frequency range. It features low power consumption of 10 mA at 10 dBm, Rx bypass and supply operation from 1.8 to 5 V, and comes in a 20-pin MCM 3.3 x 3.0 x 0.8 mm package.

Skyworks offers the SKY85337-11 highly-integrated, 2.4 GHz front-end module providing the functionality of a fully matched power amplifier (PA), power detector, harmonic filter, low-noise amplifier (LNA), and a single-pole, double-throw (SPDT) switch. The module is ideal for 802.11 ac set-top boxes, networking, personal computer systems, and WLAN enabled wireless video systems.

Qorvo offers the QPB9325 highly integrated front-end module with operation in the 3.6 – 3.8 GHz frequency range ideally suited for TDD base station, wireless infrastructure, and macro or picocell base station applications. This LNA module integrates RF functional blocks such as a pin-diode based high power switch along with two LNA stages.

Skywork’s SKYA21041 is a 5 GHz front end module comprising a single-pole, double-throw (SPDT) switch and a low-noise amplifier (LNA) with a bypass mode. This device is ideal for use in, automotive 802.11n/ac WLAN networks, automotive infotainment and telematics, and automotive connectivity modules.

Skyworks offer two new front-end modules (FEMs) for GNSS/GPS/GLONASS/Galileo/Compass/QZSS radio receiver applications in the 1559 to 1606 MHz frequency range. The SKY65933-11 and the SKY65943-11 feature an integrated low noise amplifier (LNA), and a pre-filter and post-filter. Both devices use surface-mount technology (SMT) in the form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
