RFMD adds module for ac Wi-Fi
RF Micro Devices has introduced a front-end module for notebooks and mobile devices that enables connectivity with the new version of Wi-Fi.
RFMD’s new RFFM4501E module enables 802.11ac connectivity in the 5.15 GHz to 5.85 GHz frequency band. It is optimized to support multiple applications, including notebooks, mobile routers and low-power customer premises equipment (CPE).
The device integrates a +17.5 dBm (80 MHz MCS9) PA at 3.3 volts, 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 12.5 dB of typical gain, with only 12 mA of current and an excellent noise figure of 2.5 dB. 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 that RFMD did not specify.
The ultra-small form factor (3 mm x 3 mm x 1.1 mm) and high level of integration of the RFFM4501E shrink the product footprint, reduce external component count, minimize assembly costs, speed time to market and enable product performance.
