FUNCTION
Receiver Signal Strength Output
Receiver Gain-Control Logic Input Bit 7
Receiver and Transmitter Gain-Control Logic Input Bit 6
Receiver Baseband AC-Coupling Highpass Corner Frequency Control Logic Input. For typical WiMAX
application, connect pin to ground.
Receiver Baseband Q-Channel Differential Outputs
Receiver A Baseband I-Channel Differential Outputs
Receiver VGA Supply Voltage. Bypass with a 100nF capacitor as close as possible to the pin.
Receiver Baseband Filter Supply Voltage. Bypass with a 100nF 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 22pF capacitor as close as possible to the
pin.
Receive/Transmit Mode Enable
Receiver A LNA Differential Input. Input is internally DC-coupled.
Exposed Paddle. Internally connected to GND. Connect to a large ground plane for optimum RF
performance and enhanced thermal dissipation. Not intended as an electrical connection point.
