5-21GHz Driver Amplifier
Definition of the Sij reference planes
CHA3664-QAG
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 respec.) 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 assembly, the standard techniques involving a solder paste and a suitable reflow
process can be used. For further details, see application note AN00017.
