below -54dBm (typ).
44
VCC_BUF
Supply Voltage for Receiver Baseband Buffer. Bypass with capacitor as close to the pin as possible.
Do not share the bypass capacitor ground vias with other branches.
45
RX_ON
Receiver-On Control Input. Digital CMOS input. Connect to baseband IC mode control CMOS output.
46
VCC_RMX
Supply Voltage for Receiver Downconverter. Bypass with capacitor as close to the pin as possible.
Do not share the bypass capacitor ground vias with other branches.
47
TX_ON
Transmitter-On Control Input. Digital CMOS input. Connect directly to baseband IC mode control
CMOS output.
48
RX_AGC
Receive AGC Control. Analog high-impedance input. Connect directly to baseband IC DAC voltage
output. See the
Typical Operating Characteristics
for Gain vs. V
RX_AGC
.
Exposed
Paddle
GND
