.
Mounting Recommendation(in mm)
Note: 1. The number and size of ground via holes in a
circuit board is critical for thermal and RF
grounding considerations.
2. We recommend that the ground via holes be
placed on the bottom for better RF and
thermal performance, as shown in the
drawing at the left side.

1) Total gain is sum of the 1st stage and 2nd stage amplifiers (not include filter loss).
2) NF is that of the 1st stage amplifier.
3) S11 is that of the 1st stage amplifier and S22 is that of the 2nd stage amplifier.
4) IIP3 is that of the 2nd stage amplifier measured with two tones at an input power of -34 dBm/tone separated by 1MHz.
5) Total current is the sum of the 1st stage and the 2nd stage amplifiers.
