Southwest Microwave 1832-00SF 1.85mm Female to Female 67GHz RF Adapter

The Southwest Microwave 1832-00SF is a precision 1.85mm (V) female-to-female RF coaxial adapter designed for high-frequency connections from DC to 67GHz. This inline, in-series adapter connects two compatible 1.85mm male interfaces while maintaining low VSWR and reliable microwave performance.

Featuring a passivated stainless steel housing, gold-plated beryllium copper contacts and a compact 21.64mm overall length, the 1832-00SF is suitable for vector network analyzer (VNA) testing, millimeter-wave measurements and precision RF interconnections.

Quick selection answer: Choose 1832-00SF when both mating interfaces are 1.85mm male and the application requires a female-to-female connection operating at frequencies up to 67GHz.

1. Southwest Microwave 1832-00SF Key Specifications

Southwest Microwave specifies mode-free operation through 67GHz, low insertion loss and high-frequency electrical performance. The exact insertion loss requirements should be checked against the manufacturer's latest product documentation.

2. VSWR Performance from DC to 67GHz

Voltage Standing Wave Ratio (VSWR) is a critical parameter for high-frequency RF adapters because impedance mismatch can create signal reflections and measurement uncertainty.

The Southwest Microwave 1832-00SF has the following manufacturer-specified maximum VSWR limits:

These values are maximum VSWR specifications for the adapter, not guaranteed VSWR values for a complete cable and instrument assembly.

For VNA measurements, connector cleanliness, mating torque, calibration reference planes and cable stability should also be considered.

3. 1832-00SF Dimensions and Mechanical Design

The 1832-00SF uses a compact inline construction designed to connect two 1.85mm male RF interfaces.

According to Southwest Microwave mechanical drawing 79R59725, the main dimensions are:

• Overall length: 0.852 inches (21.64mm)

• Reference plane spacing: 0.612 inches (15.54mm)

• Hex wrench size: 5/16 inch

• Connector interface: 1.85mm female on both ends

• Interface thread: M7 × 0.75-6g, as shown on the drawing

The housing is manufactured from passivated stainless steel, while the contacts use gold-plated beryllium copper. The mechanical drawing also specifies PTFE and Ultem 1000 dielectric components.

Engineers should check instrument-port clearance, connector alignment and assembly dimensions before installation.

4. What Is the 1832-00SF Used For?

The primary function of the 1832-00SF is to provide an in-series connection between two 1.85mm male interfaces without changing connector family.

Typical applications include:

• 67GHz VNA Testing: Connecting 1.85mm RF test cables, calibration setups and measurement equipment.

• Millimeter-Wave Component Evaluation: Interconnecting compatible test assemblies used to characterize amplifiers, filters, attenuators and other microwave components.

• High-Frequency Laboratory Systems: Extending or adapting 1.85mm female-to-female interface arrangements.

• Production RF Testing: Supporting precision coaxial interconnections in test fixtures, subject to connector wear and calibration requirements.

The adapter is intended for inline coaxial applications. It is not a PCB end-launch or vertical-launch connector.

5. Can the 1832-00SF Be Used for 67GHz Measurements?

Yes. The Southwest Microwave 1832-00SF is rated for operation from DC to 67GHz and is designed for precision 1.85mm RF connections.

However, the overall measurement system must also support the required frequency range.

For example, connecting a 67GHz-rated adapter to a lower-frequency cable does not extend the cable's operating range. The complete signal path—including cables, connectors, adapters and test instruments—must be evaluated.

For accurate 50–67GHz measurements, use suitable calibration procedures, inspect connector interfaces and follow the equipment manufacturer's mating instructions.

6. 1832-00SF vs Related Southwest Microwave 1.85mm Adapters

Southwest Microwave offers several 1.85mm precision adapter configurations. The main difference between these models is their connector gender and, for certain variants, the mechanical construction.

How to choose:

• Choose 1832-00SF to connect two 1.85mm male interfaces.

• Choose 1830-00SF when a female-to-male configuration is required.

• Choose 1831-00SF when both mating interfaces are female.

• Compare the mechanical drawings of 1832-00SF and 1832-02SF before treating them as interchangeable.

For applications requiring a transition between different connector families, such as 2.92mm to 2.4mm, refer to the appropriate between-series precision RF adapters. Note that a between-series adapter may have a lower rated frequency than a 1.85mm in-series adapter.

7. 1832-00SF vs 101810-00SF: What Is the Difference?

Although both adapters include 1.85mm female connectors, they serve different connection requirements.

The 1832-00SF should be selected for a 1.85mm-to-1.85mm connection up to 67GHz. The 101810-00SF is designed to connect different connector families and is limited to 40GHz.
