RFMD Unveils Complete Front End Module for Handheld
WiFi and Bluetooth Systems
N.C., May 13, 2010 (GlobeNewswire via COMTEX News Network) -- RF Micro Devices, Inc. (Nasdaq:RFMD), a global
leader in the design and manufacture of high-performance RF components and compound semiconductor technologies,
today unveiled a highly integrated new front end module (FEM) that delivers a complete integrated solution for
handset/handheld WiFi 802.11b/g/n and Bluetooth(R) systems.
FEM integrates a 2.5 GHz Power Amplifier (PA), multi-throw switch (SP3T), Low Noise Amplifier (LNA) and
power detector coupler. The RF5755 also features integrated matching circuitry with output harmonic attenuation,
reducing the bill of materials (BOM) and manufacturing costs. The RF5755 is packaged in a small 16-pin QFN package
(3mm x 3mm x 0.5mm), minimizing layout area in customer applications.
The highly integrated
delivers many features and customer benefits: high linear output power (20 dBm) allowing higher
efficiency and lower EVM for 11n applications; the ability to switch between WiFi transmit, WiFi receive, or
Bluetooth (transmit or receive); reduced need for a high loss/attenuation filter at the FEM output; high IIP3 and
gain; simultaneous receive of WiFi and Bluetooth with positive gain in both paths (utilizing the SPST switch after
the LNA); and a direct-to-battery connection eliminating the need for additional DC circuitry. Additionally, the
integrated power detector coupler decreases sensitivity to voltage supply, temperature, and VSWR and improves the
accuracy of the closed loop power control.
FEM is fully tested, including EVM and all DC parameters, providing a reduced size, single-placement
solution that minimizes system footprint, reduces costs, and accelerates time-to-market for high linear output
