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 3.6V first with PA_EN < 0.4V. Leakage current should be <10uA. 3. Refer to switch operational truth table to set the control lines at the proper levels for TX High Power. All OFF voltages must be < 0.2V (cannot be 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 (or 255mA @ 5V) +/- 20mA for a typical part but the actual operating current will be based on the output power desired. 802.11a/n/ac Transmit Turn On Sequence (See Transmit Timing Diagram) 1. Turn ON power supply. 2. Turn ON PA_EN. 3. Apply RF. 802.11a/n/ac Transmit Turn Off Sequence 1. Turn OFF RF. 2. Turn OFF PA_EN. 3. 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. |
