High-Performance Wi-Fi
Solutions for Customer Premise Equipment Applications
Microsemi has a growing portfolio of world-class RF products for Wi-Fi 802.11 a/b/g/n/ac applications. Microsemi
Wi-Fi solutions include high-performance front-end modules (FEMs), power amplifiers (PAs), and low-noise
amplifiers (LNAs). Featuring highly integrated monolithic RFIC design, Microsemi’s latest generation of mid-
powered FEMs is optimized for long-packet EVM performance and high efficiency, and is ideally suited for
client-based access points, gateways, and 4K media streaming platforms.
Microsemi’s 5-GHz/2-GHz FEM is the industry’s first dual-band solution,
integrating all functions for PA, LNA, switches, band-edge filter, diplexer,
harmonic and out-of-band rejection, and impedance matching in a single
monolithic die. Low current consumption, 3.3-volt supply, and 4mm-by-3mm
compact size are ideal for smart television and OTT media platforms.
Microsemi’s family of high-linearity power amplifiers features the latest in
2.4-GHz and 5-GHz amplifiers. With market-leading current consumption,
Microsemi solutions deliver the high power required in newer 802.11ac
systems, critical for thermal management of today’s newer 4×4 and 8×8
MIMO configurations.
