RF Micro Devices, Inc.
RFMD, a global leader in the design and manufacture of
high-performance radio frequency components, today introduced the
highly-integrated RFFM4501E front end module (FEM) for 802.11ac notebook and
mobile equipment applications. RFMD's newest WiFi FEM meets or exceeds the
system requirements for 802.11ac connectivity in the 5.150GHz – 5.850GHz
frequency band and is optimized to support multiple applications, including
notebooks, mobile routers, and low-power customer premises systems.
The RFFM4501E integrates a +17.5dBm (80MHz MCS9) PA at 3.3V, a low insertion
loss/high isolation single pole two throw (SP2T) switch, harmonic filtering,
and a low noise amplifier (LNA) with bypass mode, for equipment manufacturers
seeking to adjust receive sensitivity. The receive chain provides 12.5dB of
typical gain with only 12mA of current and an excellent noise figure of 2.5dB.
Separate Rx/Tx 50 Ohm ports simplify matching and provide input and output
signals for both the transmit and receive paths.
The RFFM4501E is optimized to mate with the 802.11ac chipset of a leading
semiconductor company.
