Functional Applications:
nEqualizer is utilized as a compensation circuit to correct
for a loss slope created by other elements within a circuit
[such as in amplier stages].
nUsed with SONET modules in conjunction with DC
blocking capacitors adjacent to ampliers.
Benets:
nSuperior microwave performance
nExcellent repeatability
nEase of assembly
nCustom designs possible

Physical Characteristics
Die Attachment Recommendations:
1) Equalizer width should be approximately as
wide as 50 ohm line trace on PCB.
2) The gap in the microstrip line should
be nominally equal to dimension Lr.
3) Vacuum pick-up tool recom-
mended for component handling.
If pressure is to be applied during
component placement, it should
be done uniformly across the part.
4) Thin, unmounted circuit boards are
prone to warpage during reow. This
can cause solder attach defects and
cracking of components during handling or
subsequent housing installation.
Mechanical outline drawings for equalizers listed above are available. Please contact DLI Applications Engineering for details.
