RFMD launches 3-5V 802.11n/ac high-linearity WiFi front-end modules

RF Micro Devices Inc of Greensboro, NC, USA says that its new high-linearity WiFi front-end modules (FEMs) provide complete integrated solution in a single FEM for WiFi systems.

Each of the devices integrates a power amplifier (2.4-2.5GHz for the RFFM4203; 4.9-5.85GHz for the RFFM4501), Tx/Rx switch (SP3T for the RFFM4203; SPDT for the RFFM4501), low-noise amplifier (LNA) with bypass, and a power detector coupler for improved accuracy.

The ultra-small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. This simplifies the total front-end solution by reducing the bill of materials, system footprint, and manufacturability costs, says RFMD.

With an optimized dynamic error vector magnitude (EVM) design, output powers for the RFFM4203 are 20.5dBm (11g/n, 5V <3% dynamic EVM), 19dBm (11n, 3.3V 2.5% dynamic EVM) and 17dBm (11ac, 3.3V 1.8% dynamic EVM). Output powers for the RFFM4501 are 20dBm (11a/n, 5V <3% dynamic EVM), 17dBm (11n, 3.3V <3% dynamic EVM) and 14dBm (11ac, 3.3V <1.8% dynamic EVM).

Applications include: WiFi (RFFM4203 for IEEE 802.11b/g/n/ac and RFFM4501 for IEEE 802.11a/n/ac); ISM-band solutions (RFFM4203 for 2.4-2.5GHz and RFFM4501 for 4.9-5.85GHz); portable battery-powered equipment; and laptops, WiFi access points, gateways, and set-top boxes.

Provided in a 3mm x 3mm x 1.0mm, 16-pin laminate package, pricing (in 100-unit quantities) begins at $1.73 each for the RFFM4203 and $2.27 each for the RFFM4501.
