Front-end Module (FEM)

RichWave offers a broad line of front-end modules (FEMs) for WiFi connectivity solutions covering the spectrum from AP routers and consumer PCs/laptops to mobile/portable phones.

RichWave FEM products enable customers to achieve cost-effective, small form-factor solutions by:

leveraging multi-process technologies, including GaAs/SiGe/SOI CMOS, to optimize EVM performance as well as providing the best and most cost-effective solution
offering advanced MCM (multi-chip-module) packaging and IPD (integrated passive device) process to achieve an on-chip harmonic filter as well as a substrate-free assembly
providing a wide variety of RX FEM (LNA/SW) and full FEM (PA/LNA/SW) solutions to meet WiFi 802.11a,b,g,n,ac requirements in medium power (+21dBm and lower) and high power (over +21dBm) applications
