This simplifies the total front end solution by reducing the bill of materials, system footprint, and manufacturability cost. Each device is provided in a 2.5-mm x 2.5-mm x 0.45-mm, 16-pin QFN package.
The RFFM8202 and RFFM8204 cover 2.4 GHz to 2.5 GHz, while the RFFM8502 covers 4.9 GHz to 5.85 GHz. The RFFM8202 integrates a PA, LNA with bypass mode, power detector, SP3T, and filtering, while the RFFM8204 integrates a PA, SP3T, power detector and filtering, and the RFFM8502 integrates a 5 GHz PA, SP2T, switch, LNA, and power detector
Both the RFFM8202 and RFFM8204 deliver 19 dBm 11g OFDM at 2.5% EVM, and 21 dBm meeting 11b spec mask, while the RFFM8502 provides 17.5 dBm, 11a, OFDM at 2.5% EVM.
Other features include high linearity, input and output matching to 50 Ω, and support for a wide voltage supply range.
All the devices are able to meet the demands of the evolving WiFi market and come in a low height package, suited for SiP and CoB designs.
Typical applications include cellular handsets, mobile devices, tablets, consumer electronics, gaming, netbooks/notebooks, TV/monitors/video and smart energy.
