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.
