1st Crystal Input
Analog Power-Supply Voltage for RF Sections. AVDD is connected to an on-chip +3.0V low-dropout
regulator. Decouple to AGND with a 0.1µF capacitor.
Low-Noise Amplifier Input
Low-Noise Amplifier Source for External Inductive Degeneration. Connect an inductor to AGND to set
LNA input impedance.
Low-Noise Amplifier Output. Connect to mixer through an LC tank filter.
Differential Mixer Input. Must be AC-coupled to driving input.
Differential Mixer Input. Bypass to AGND with a capacitor.
330Ω Mixer Output. Connect to the input of the 10.7MHz IF filter.
Analog Ground
Differential 330Ω IF Limiter Amplifier Input. Bypass to AGND with a capacitor.
Differential 330Ω IF Limiter Amplifier Input. Connect to output of the 10.7MHz IF filter.
