In the datasheet (rev A) of ADL5523 on page 17 in table 7 are TR1 and TR2.

The dimension of these rows is mm x mm. Is this the size of the resistors?

What about the values of TR1 and TR2:
Are they fixed?
What values do they have?


I’ve attached a document to help explain the answer to your question. On the
evaluation board there is a length of transmission line. It is 8mm x 0.6 mm The
position of C3 breaks this line into 2 pieces.

We are providing the length of these two pieces based on the position of C3 at
different frequencies. (listed  in table 7) Along the edge of the line there
are silk screened numbers. These are just an index to help ease retuning the
board for different frequencies.
