TUSONIX 77, 78 and 79 Series

he TUSONIX 77, 78 and 79 Series Filtered
Assembly Plates provide ease of installation
and line customization of standard size
plates. Filter Plates are an efficient and cost effec-
tive solution for filtering multiple lines into, or be-
tween, different system compartments.
For higher frequency applications (above 50 MHz),
filter plates can be more effective than typical sur-
face mount solutions. The inherent shielding char-
acteristic of the plates creates an effective RF bar-
rier offering excellent insertion loss and isolation for
frequencies above 5 MHz. The preassembled
plates, which are 100% tested for critical param-
eters, greatly reduce the time and resources that
are required to individually install solder mount fil-
ters.
The 77 Series Quick Connect and 78 Series Minia-
ture Quick Connect Filter Plates (see pages 2-3)
feature a base plate with built in installation clips.
These clips allow for cost effective mounting into
the system bulkhead without the expense or time
associated with traditional hardware.
The Quick Connect Filter Plate offers one or two
rows totaling up to 26 lines. The Miniature Quick
Connect Filter Plate provides a lower profile and up
to 10 lines. Up to 40 lines are available on the stan-
dard bolt-in filter plate in the two row configuration.

TUSONIX’ Miniature Quick Connect Filter
Plates offer the same ease of installation
as the larger Quick Connect Filter Plates,
while offering a low profile for limited area
applications.
These Quick Connect Filter Plates are avail-
able in two lengths offering up to 10 lines
with the longer plate option. Each line can
be customized using the electrical charac-
teristics in the table on page 5. If other spe-
cial requirements are needed, contact Cus-
tomer Engineering at 520-744-0400.
