Southwest Microwave 101410-00SF 2.92mm to 2.4mm 40GHz RF Adapter

The Southwest Microwave 101410-00SF is a precision 40GHz between-series RF coaxial adapter designed to connect a 2.92mm (K) male interface to a 2.4mm male interface. The adapter itself features a 2.92mm female (jack) connector on one end and a 2.4mm female (jack) connector on the other.

With a DC–40GHz operating range, low VSWR and inline stainless steel construction, the 101410-00SF is suitable for precision microwave measurements, RF test equipment interconnections and other applications requiring a transition between these two connector families.

1. Key Specifications of 101410-00SF

The manufacturer specifies mode-free operation through 40GHz and consistent electrical performance between production units. For detailed dimensional requirements, refer to the official drawing 79Y53673.

2. What Is the Southwest Microwave 101410-00SF Used For?

The primary purpose of the 101410-00SF is to provide a precision coaxial transition between two different RF connector families without requiring replacement of the existing cable or equipment interface.

For example, an engineer may need to connect a 2.92mm male cable assembly to an RF instrument fitted with a 2.4mm male connector. The 101410-00SF provides the required female-to-female transition.

Typical applications include:

• Vector Network Analyzer (VNA) testing: Connecting precision RF test cables and instrument ports with different connector interfaces.

• Microwave component characterization: Testing filters, amplifiers, attenuators and directional couplers.

• RF laboratory setups: Adapting 2.92mm and 2.4mm coaxial test assemblies.

• Automated Test Equipment (ATE): Supporting test fixture interconnections operating within the adapter's rated frequency range.

Actual suitability depends on the complete test assembly, including connector condition, cable ratings, RF power and measurement uncertainty requirements.

3. 2.92mm Female to 2.4mm Female: Connector Compatibility

The 2.92mm connector, also known as the K connector, is commonly used in microwave systems operating up to 40GHz. The 2.4mm connector family is commonly associated with operation up to 50GHz.

Although these connectors may appear similar, their mechanical interfaces are different. Engineers should not assume that 2.92mm and 2.4mm connectors can be directly mated.

The 101410-00SF provides a purpose-designed transition between these interfaces while maintaining the manufacturer's specified electrical performance through 40GHz.

Important: The presence of a 2.4mm connector does not make the 101410-00SF a 50GHz adapter. The maximum rated operating frequency of this exact model is 40GHz.

4. 101410-00SF Mechanical Dimensions and Construction

Mechanical fit is important when selecting an inline adapter for compact RF equipment, instrument ports and precision test assemblies.

According to the Southwest Microwave mechanical drawing, the 101410-00SF has the following dimensions:

• Overall length: 0.808 inches (approximately 20.52mm).

• Distance between connector reference planes: 0.612 inches (approximately 15.54mm).

• Hex wrench feature: 0.312 inches nominal, approximately 7.92mm.

• 2.92mm female connector on one side.

• 2.4mm female connector on the opposite side.

The housing uses passivated stainless steel, while the electrical contacts use gold-plated beryllium copper. The manufacturer's drawing identifies Ultem 1000 and KEL-F dielectric materials.

Both connector interfaces follow the applicable MIL-STD-348 dimensional requirements specified by Southwest Microwave.

Before installing the adapter, check the available clearance around the mating ports, connector alignment and applicable torque requirements.

5. VSWR Performance and RF Measurement Considerations

Low VSWR is especially important in precision microwave measurements because impedance mismatch produces reflected signals that can contribute to measurement error.

Southwest Microwave specifies the following maximum VSWR values for 101410-00SF:

For VNA measurements, engineers should account for the added adapter in the calibration and measurement setup. Other relevant factors include insertion loss, connector repeatability, cable stability and reference-plane placement.

When measuring sensitive microwave devices, inspect connector interfaces for contamination or damage and use the manufacturer's recommended mating procedures.

6. 101410-00SF vs Related Southwest Microwave Models

The 101410-00SF is one of four connector-gender configurations in Southwest Microwave's 2.92mm-to-2.4mm, 40GHz adapter family.

These four models serve different mating configurations. For the mixed-gender versions, verify the gender of each connector family using the specific mechanical drawing before ordering.

If your system requires a transition from 2.92mm to 1.85mm rather than 2.4mm, consider the Southwest Microwave 101810-00SF family. Note that these between-series adapters are also rated to 40GHz.

7. When Should You Choose 101410-00SF?

The 101410-00SF is a suitable candidate when all of the following conditions are satisfied:

• Your RF assembly requires a 2.92mm-to-2.4mm connection.

• Both mating equipment or cable interfaces are male.

• The maximum operating frequency does not exceed 40GHz.

• Low VSWR is important for the RF measurement or interconnection.

• An inline adapter is mechanically suitable for the system.

It is not the correct choice for applications requiring 50GHz operation, PCB end-launch mounting, or a male connector on either end of the adapter.

9. Frequently Asked Questions

Is Southwest Microwave 101410-00SF a 40GHz or 50GHz adapter?

The 101410-00SF is rated for DC to 40GHz. Although it includes a 2.4mm connector interface, its specified maximum operating frequency is 40GHz, not 50GHz.

Is 101410-00SF female-to-female?

Yes. It has a 2.92mm female (jack) connector on one end and a 2.4mm female (jack) connector on the other. Both mating cable or equipment connectors therefore need appropriate male interfaces.

Can 101410-00SF be used for PCB end-launch applications?

No. The 101410-00SF is an inline coaxial adapter, not a PCB end-launch connector. For direct PCB mounting, select an appropriate Southwest Microwave end-launch or vertical-launch connector.
