NAME
FUNCTION
1
VCC_RF2
DC Power Supply for LNA. Connect to a +3.3V low-noise supply. Bypass to GND with a 1nF capacitor
connected as close as possible to the pin. Do not share capacitor ground vias with other ground connections.
2
VCC_RF1
DC Power Supply for LNA. Connect to a +3.3V low-noise supply. Bypass to GND with a 1nF capacitor
connected as close as possible to the pin. Do not share capacitor ground vias with other ground connections.
3
GND
Ground. Connect to board’s ground plane for proper operation.
4
RFIN
Wideband75ΩRFInput.ConnecttoanRFsourcethroughaDC-blockingcapacitor.
5
GC1
RF Gain-Control Input. High-impedance analog input with a 0.5V to 2.7V operating range.
VGC1 = 0.5V corresponds to the maximum gain setting.
6
VCC_LO
DC Power Supply for LO Generation Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with
a 1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with other
ground connections.
7
VCC_VCO
DC Power Supply for VCO Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with a 1nF
capacitor connected as close as possible to the pin. Do not share capacitor ground vias with other ground
connections.
