Extended-Frequency SMA Connectors
This brochure introduces two new series of connectors that extend SMA performance beyond the MIL-PRF-39012
upper frequency limit of 18 GHz, while maintaining MIL-STD-348 mating characteristics for backward
compatibility with standard SMA connectors when required.
With both 26.5-GHz precision types and 27.0-GHz high-performance types available, you can choose the best
price / performance balance for your application, with no need to “overspecify.”
This brochure features configurations to fulfill most standard applications, but any item shown can be customized
for your specific needs.
SMA 26.5-GHz Connectors
These extended-frequency, precision SMA series
connectors feature maximum VSWR of 1.15:1
from DC to 18 GHz, and 1.25:1 from 18 to
26.5 GHz.
Along with cable connectors for semi-rigid cable,
our SMA 26.5-GHz line includes receptacles with
post contacts and integral metal contact rings, and
field-replaceable types in a variety of flange sizes.
These field-replaceable receptacles are available as
jacks or plugs, each with a choice of air or PTFE
rear dielectric matching sections, and with or
without EMI gaskets.
The field-replaceable receptacles are available for
use with hermetic seals or accessory pins with
diameters of .012, .015, .018, .020, or .036 inches.
Standard hermetic seals are also shown in this
brochure, and can be modified to a wide range
of configurations to match your application
requirements.
Three types of SMA 26.5-GHz adapters are also
included in this series, as are bulkhead receptacles.
Performance Features:
Mode free through 26.5 GHz
Low reflection loss (VSWR)
Low Insertion Loss
Low RF Leakage > -100 dB
Consistent Unit to Unit Performance
All materials meet the Outgassing Requirements

SMA 27.0-GHz Connectors
These high-performance SMA connectors feature maximum
VSWR of 1.10:1 from DC to 18 GHz, and 1.15:1 from
18 to 27.0 GHz.
They are designed to provide enhanced durability and
reliability in a “field grade” production connector.
The internal design is optimized using state-of-the-art
Electromagnetic Finite Element Analysis model simulation to
provide low reflection coefficient, with mode free operation to
27.0 GHz.
In addition, this connector series provides -100 dB RF leakage
due to the precision finish on the interface and mounting
surfaces to assure a solid 360-degree contact in the critical RF
return path, and the absence of epoxy holes in the connector
body. The design of the internal structure provides a reliable and
symmetrical axial captivation by mechanical means with a mini-
mal disturbance to the transmission line characteristics and has a
maximum continuous service temperature of 165˚ C.
SMA 27.0 GHz field replaceable connectors are available in
six common mounting flange configurations. Both the field
replaceable and thread-in (spark plug) connectors are available
for use with hermetic seals or accessory pins with diameters of
.009, .012, .015, .018, .020, and .036 inches. Standard hermetic
seals are also shown in this brochure, and can be modified to
a wide range of configurations to match your application
requirements.
These connectors are machined to exacting tolerances and the
highest quality standards on modern CNC turning centers, and
assembly is tightly controlled and monitored to ensure peak
consistency of performance from unit to unit.
Performance Features:
Mode free through 27.0 GHz
Low reflection loss (VSWR)
Low Insertion Loss
Low RF Leakage > -100 dB
Extended Operating Temperature (+165˚ C)
Phase Stable
Consistent Unit to Unit Performance
Rigid center contact captivation using high temperature
Ultem 1000 support bead
All materials meet the Outgassing Requirements of NASA
