Full-line catalog (does not include SMA 26.5 and 27.0 GHz types)

Delta SMA 26.5-GHz Precision 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.

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 of NASA Publication 1124

Delta SMA 27.0-GHz Precision 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 minimal disturbance to the transmission line characteristics and has a maximum continuous service temperature of 165¾ C

The field-replaceable receptacles are available for use with hermetic seals or accessory pins with diameters of .012, .015, .018, .020, or .036 inches.

Three types of SMA 27.0-GHz adapters are also included in this series, as are bulkhead receptacles.

Performance Features:

Mode free through 27.0 GHz • Low reflection loss (VSWR) • Low Insertion Loss • Low RF Leakage > -100 dB

Extended Operating Temperature (+165¾ C) • Phase Stable

Rigid centercontact captivation using high temperature
Ultem 1000 support bead

Consistent Unit to Unit Performance • All materials meet the Outgassing Requirements of NASA Publication 1124
