Description and Usage
Buffered LO port. There is an internal DC block on this port, which is matched to 50Ω.
Supply voltage for bias circuitry and LNA. This pin draws 8mA, typically. Decouple with 0.01uF within 0.25 inch of
package.
LNA IN0 is an auxiliary input and has characteristics similar to the LNA IN1 input port. Best performance is achieved
with external noise-matching network. Internally DC blocked.
Input port selection switch. CMOS-compatible drive, switches input ports from LNA IN1 to LNA IN0. Low=IN0,
High=IN1.
LNA IN1 is the primary input port. Best performance is achieved with external noise-matching network. Internally DC
blocked.
Output port from switched LNA section. Internally matched to 50Ω. Internally DC blocked.
Mixer RF Input port. Image stripping band pass filtering before Mixer section improves noise and spurious performance.
No return to ground is required. Shunt L recommended for IF suppression.
LO buffer tuning, inductor to ground.
Mixer IF signal port. Open “collector-”type 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.
