Description and Usage
Mixer LO input. Matched to 50Ω. Internally DC blocked.
Mixer LO buffer Vdd. Bypass cap required.
LNA gain select control Vdd. Bypass cap required.
LNA gain select line. Logic HIGH = high gain, logic LOW = low gain
LNA RF Input port. Noise matching required. External DC blocking required.
LNA Output port. Open drain output requires connection to Vdd and optimal impedance matching.
Mixer RF Input port. Matched to 50Ω. Internally DC blocked.
LO buffer tuning, inductor to ground.
Mixer IF signal port. Open drain output requires connection to Vdd and impedance matching to load.
Ground connection. Keep physically short for stability and performance. Use several via holes immediately adjacent to
the pins down to backside ground plane.
