RFFM4204 WiFi 802.11b/g/n/ac Front End Module 2.4GHz to 2.5GHz VCC1 GND VCC2 VCC3 GND The RFFM4204 provides a complete solution in a single front end module (FEM) by integrating the power amplifier (PA), low noise amplifier (LNA) with bypass, power detector, a Single Pole Double Throw (SPDT) switch, and some filtering for harmonic rejection. The integrated matching greatly reduces the number of external components and layout area in the customer application. This simplifies the total front end solution by reducing the bill of materials, system footprint, and manufacturing cost. The RFFM4204 is provided in a 6.0mm X 6.0mm X 0.9mm 24-pin laminate package. The FEM meets or exceeds the RF front end needs of IEEE 802.11b/g/n/ac WiFi RF systems. 24 23 22 21 20 GND 3 17 GND TX 4 16 GND GND 5 15 ANT PA_EN 6 14 GND NC 7 8 9 10 11 12 LNA_EN 18 C_TX VDD 2 RX GND PDET 1 NC VBIAS 19 GND RFFM4204 Package: Laminate, 24-pin, 6.0mm x 6.0mm x 0.9mm Features ■ Voltage Supply: 5V ■ POUT = 24dBm, 256QAM MCS9 HT40 at 1.8% DEVM ■ POUT = 25dBm, 64QAM MCS7 HT20 and HT40 at 3% DEVM ■ Input and Output Matched to 50Ω ■ Integrated PA, SPDT, and LNA with bypass ■ High Impedance Enable Pin Applications ■ IEEE 802.11b/g/n/ac WiFi Systems ■ Wireless Access Points, Gateways, Router and Set Top Box Applications ■ ISM Band Transmitter Applications 13 C_RX Functional Block Diagram Ordering Information RFFM4204SB Standard 5-piece sample bag RFFM4204SQ Standard 25-piece sample bag RFFM4204SR Standard 100-piece reel RFFM4204TR13 Standard 2500-piece reel RFFM4204PCK-410 Fully assembled evaluation board w/5 pc bag RF Micro Devices Inc. 7628 Thorndike Road, Greensboro, NC 27409-9421 For sales or technical support, contact RFMD at +1.336.678.5570 or [email protected]. ® DS141017 ® RF MICRO DEVICES and RFMD are trademarks of RFMD, LLC.
