RFFM8506
4.9GHz to 5.85GHz 802.11a/n/ac WiFi
Front End Module
The RFFM8506 provides a complete integrated solution in a single front
end module (FEM) for WiFi 802.11a/n/ac systems. The ultra-small factor
and integrated matching minimizes layout area in the customer’s
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 manufacturing cost. The RFFM8506
integrates a 5 GHz power amplifier (PA), single pole double throw switch
(SP2T) and an LNA with bypass. The device is provided in a 2.5mm x
2.5mm x 0.45mm, 16-pin QFN package. This module meets or exceeds
the RF front end needs of IEEE 802.11a/n/ac WiFi RF systems.

Timing Sequence Notes
802.11a/n/ac Transmit Biasing Instructions
1. Connect the FEM to a signal generator at the input and a spectrum analyzer at the output. Terminate
unused ports with 50 Ohms
2. Set the power supply voltage to 3.0-4.2V first with PA_EN < 0.4V. Leakage current will be <15uA typical.
3. Refer to switch operational truth table to set the control lines at the proper levels for WiFi TX. All OFF
voltages must be < 0.4V (do not leave floating.)
4. Turn on PA_EN with levels indicated in the datasheet. PA_EN controls the current drawn by the
802.11a/n/ac power amplifier and the current should quickly rise to ~200mA +/- 20mA for a typical part but
the actual operating current will be based on the output power desired. Be extremely careful not to exceed
5.0V on the PA_EN pin or the part may exceed device current limits.
802.11a/n/ac Transmit Turn ON Sequence (See Transmit Timing Diagram)
1. Turn ON power supply.
2. Turn ON PA_EN.
3. Turn ON SW_CTL.
4. Apply RF.
802.11a/n/ac Transmit Turn OFF Sequence
1. Turn OFF RF.
2. Turn OFF SW_CTL.
3. Turn OFF PA_EN.
4. Turn OFF power supply.
802.11a/n/ac Receive
1. To receive WiFi set the switch control lines per the truth table.
2. Antenna port is input and RX port is output for this test.
3. Follow Timing Diagram for biasing instructions.
