WiFi front end modules feature tiny form factors

October 11, 2012 // By Jean-Pierre Joosting
RFMD’s latest high linearity WiFi front end modules provide complete integrated front end solutions for WiFi systems. Optimized for 802.11n Dynamic EVM and 100% RF production tested, the RFFM8200 is a 2.4 GHz to 2.5 GHz power amplifier while the RFFM8500 is a 4.9 GHz to 5.85 GHz power amplifier.

Each of these devices integrates a power amplifier, switch, LNA with bypass, and a power detector coupler for improved accuracy and is provided in a 3-mm x 3-mm x 1.0-mm, 16-pin laminate package.

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 with a reduced bill of materials, smaller system footprint, and lower manufacturing cost.

The RFFM8200 features Pout of 18 dBm, 11n, 3.3-V at 2% dynamic EVM and 21 dBm, 11b, meeting spectral mask. The RFFM8500 features Pout of 16 dBm, 11n, 54 Mbps at 2% dynamic EVM.
