CHA3666-QAG
5.8-17GHz Low Noise Amplifier
Definition of the Sij reference planes
The reference planes are defined from the
footprint of the recommended
characterization board shown below under
the number 96272.
The reference is the symmetrical axis of
the package. The input and output
reference planes are located at 2.65mm
offset (input wise and output wise
respectively) from this axis. Then, the
given Sij incorporates this land pattern.

SMD mounting procedure
The SMD leadless package has been designed for high volume surface mount PCB
assembly process. The dimensions and footprint required for the PCB (motherboard) are
given in the drawings above.
For the mounting process standard techniques involving solder paste and a suitable reflow
process can be used. For further details, see application note AN0017.
