Recommended Test Plans

(see next page)
Single Lot Control: SMI builds to stock in large quantities
so small quantities requiring single lot control of all raw
materials are usually available in stock.
Qualification Testing: SMI can perform most of these
tests in-house and will coordinate with outside labs
for those other tests, such as shock and vibration that
require special equipment. SMI will design and build
the necessary tools to facilitate these tests.

Source Inspections: SMI has hosted many source inspections in coordination with several major space and
hi-rel customers, and is familiar with what is required to
facilitate and streamline them.
Adapters
Source Control Drawings (SCD): SMI has an extensive database of customer source control drawings for
commercial and hi-rel applications. Due to extensive
experience working with SCD’s, SMI is frequently asked
to contribute technical material and assistance in their
creation.
Destructive Physical Analysis (DPA): When DPA is required, SMI works with several quality labs that provide
DPA services. SMI oversees the testing and integrates
the DPA results into the ATR.
End Launch

Material Traceability: All material used in connector assemblies has traceability to raw material. This allows
SMI to use any item in stock for space level applications.

Outgassing: All material used in connector assemblies
meet NASA outgassing requirements. (See page 97)
Space Screening: Test plans are generated in accordance with SCD requirements and most tests are
performed in-house. Tests are performed and the results
recorded in accordance with the test plan. The results
are then combined with material certs and lot traceability
information into a document called an Acceptance Test
Report (ATR).

COTS Considerations
SSMA
Connectors
Southwest Microwave uses MIL-PRF-39012 as a reference for interface specifications and test methods. There
are additional tests SMI recommends be performed in
addition to MIL-PRF-39012 to ensure proper performance
during the actual usage of the connectors. The most important of these is thermal shock to ensure the interface
and the electrical performance are stable over the full
temperature range. MIL-PRF-39012 does not require testing after temperature cycling.

Average Power Ratings for Coaxial Connectors
Super SMA
Connectors
High power failure is caused by the generation of heat at the contacting surfaces.
When the contact resistance approaches surface resistance including skin effect, the
ultimate power handling level will be approached. Application results are affected by
heat-sinking of the connector plus the connector’s construction and use of highertemperature materials. Another limiting factor is altitude because of the connector's
increasing inability to dissipate heat as altitude increases. Power derating factors for
temperature and altitude are provided on the following table.
Thus, there is not an absolute power handling figure for a connector type. Results may
vary from supplier-to-supplier due to design, materials and manufacturing latitudes
taken by each. Therefore published power ratings are typically conservative.

The following graph summarizes industry acceptable average power rating for a variety
of coaxial connector types. The key characteristic that determines average power
handling capabilities for mated coaxial connectors is its ability to pass high current and
keep heat-rise to a moderate temperature. This heating directly relates to contact
resistance. Contact resistance is a function of contact surface area. Therefore properly
formed center contacts are critical. If connectors are long, then conductor length
resistance may start to dominate. The average power rating decreases with frequency
because the resistive losses increase with frequency.

Extended Power Super SMA
Southwest Microwave’s “Extended Power Super SMA” connectors provide additional
power handling capabilities above most standard SMA connectors because they operate
reliably at higher temperatures (165°C) with moderate power (160W) or at higher /
extended power (250W) at 125°C. The temperature rating as specified is the temperature that the connector will withstand and still meet the electrical specifications.
As a basic guideline, the Extended Power Super SMA will handle an additional 100W
average power above what is represented in the following power chart for SMA. Therefore the recommended maximum power rating for Extended Power Super SMA connector is 250W CW at Ku-band (12.4–18.0 GHz), at a maximum temperature of 125°C.

When the proper procedure for mating microwave connectors is followed, no rotational
torque is applied to the center conductors.
If the body of either connector is rotated, this
is improper and can apply a rotational torque
to the center conductor. All Southwest Microwave connectors have the center conductor
rigidly captured to the outer housing. The
center conductor captivation is, in most cases,
accomplished with a high temperature plastic
bead. This bead provides high axial retention at extended temperatures, but does not
provide for any rotational resistance. Therefore
proper mating is strongly recommended.
