Front end modules target next generation WiFi applications

June 19, 2012 // By Jean-Pierre Joosting
RF Micro Devices has released four high-performance front end modules (FEMs) for next generation WiFi applications. The RFMD® RFFM8200, RFFM8500, RFFM8202, and RFFM8502 are highly integrated FEM solutions covering multiple WiFi standards and frequency bands, particularly IEEE802.11n and the emerging 802.11ac specification.

The FEMs claim industry-leading linear power and dynamic error vector magnitude (EVM) performance in support of the latest reference designs from the world's leading WiFi chipset providers.

The WiFi market is growing rapidly, driven by increasing consumer demand for access to mobile broadband data and the expanding operator requirements for data offload to accommodate increased cellular and cable network services. By 2015, it is projected the WiFi FEM mobile/embedded and consumer premises equipment markets will exceed $1.8 billion.

Dynamic EVM is a critical design specification for high data rate WiFi systems. While competitor solutions have traditionally measured static EVM performance, these FEMs achieve superior dynamic EVM to deliver best-in-class real-world WiFi system performance. This enables optimum data throughput at increased operator range, current savings through optimal transmit and receive speeds, and an enhanced user experience during video streaming, gaming, and other high data rate applications.

The RFFM8200/8202 (2.5 GHz) and RFFM8500/8502 (5 GHz) FEMs integrate the power amplifier, LNA, and switch functionality into a single plastic QFN package. Designed for both "chip on board" and "system-in-package" (SiP) implementations, both product families deliver best-in-class linear output power while operating over a wide range of operating voltages. The highly integrated FEMs significantly reduce external component count outside the core WiFi chipset.

The comapny's broad portfolio of WiFi products are being shown at the IEEE International Microwave Symposium in Montreal, Canada.
