FUNCTION
Rx Front-End and Tx Gain-Control Digital Input Bit 6
2.4GHz/5GHz LNA Supply Voltage. Bypass with a capacitor as close to the pin as
possible. Do not share the bypass-capacitor ground vias with any other branches.
Rx Front-End Gain-Control Digital Input Bit 7
No Connection. Leave unconnected.
LNA Ground. Make connections to ground vias as short as possible. Do not share ground
vias with any of the other branches.
5GHz Single-Ended LNA Input. Requires AC-coupling and external matching network.
LNA Ground. Make connections to ground vias as short as possible. Do not share ground
vias with any other branches.
5GHz Tx PA Driver Differential Outputs. Requires AC-coupling and external matching
network (and balun) to the external PA input.
Tx RF Supply Voltage. Bypass with a capacitor as close to the pin as possible. Do not
share the bypass-capacitor ground vias with any other branches.
Tx Mode Enable Digital Input. Set high to enable Tx (see Figure 1).
DAC Current Output. Connect directly to the external PA bias pin.
Tx Baseband Filter Supply Voltage. Bypass with a capacitor as close to the pin as
possible. Do not share the bypass-capacitor ground vias with any other branches.
Tx Baseband I-Channel Differential Inputs
Tx Baseband Q-Channel Differential Inputs
Tx Upconverter Supply Voltage. Bypass with a capacitor as close to the pin as possible.
Do not share the bypass-capacitor ground vias with any other branches.
This Analog Voltage Input is Internally Biased to a Bandgap Voltage. Connect an external
