FUNCTION
Receiver Baseband AC-Coupling Highpass Corner Frequency Control Logic Input. Connect to
ground if not being used.
Receiver Baseband Filter Supply Voltage. Bypass with a capacitor as close as possible to the pin.
Transmitter Baseband I-Channel Differential Inputs
Transmitter Baseband Q-Channel Differential Inputs
Receiver Downconverters Supply Voltage. Bypass with a capacitor as close as possible to the pin.
Mode Control Logic Input. See Table 1 for operating modes.
Mode Control Logic Input. See Table 1 for operating modes.
Exposed Paddle. Connect to the ground plane with multiple vias for proper operation and heat
dissipation. Do not share with any other pin grounds and bypass capacitors’ ground.

Note 5: Set SPI Reg 24 D1:D0 = “00” for single-transceiver mode of operation. Set SPI Reg 16 D4:D3 = “11,” Reg 24 D8 = “1,” Reg
24 D1:D0 = “01” for MIMO master configuration.
Note 6: Unused states of SPI Reg 16, D1:D0 above are not tested, and therefore, should not be used.
Note 7: Parts of transceiver may be selectively enabled.
Note 8: PA bias DAC may be kept active in these non-transmit mode(s) by SPI programming.
Note 9: Set SPI Reg 5 D5 = “1” to mux AM detector output to RXBB pins.
Note 10: Set SPI Reg 26 D3 = “1.”
Note 11: CLKOUT signal is active independent of the states of SPI Reg 16, D1:D0, and is only dependent on the states of ENABLE
and RXTX pins. However, to ensure that the rest of the chip is off when the CLKOUT is active in the clock-out mode, set SPI
Reg 16, D1:D0 to “00” as shown above.
